Answer:
1. 22
2. 7*3=21
3. 2
4. 8
Step-by-step explanation: (I am not sure what level math you are as you put HS but I used simple algebra in my answers)
1. Using algebra I put the missing variable as x.
"add 5 to me" is x+5.
"divide by 9, you get 3"
[tex]\frac{x+5}{9}[/tex] = 3
Begin solving by multiplying 9 to the 3 on the other side
x+5 = 27
Subtract 5 to get x by itself
x = 22
2. An equivalent multiplication sentence can be found using algebra.
21 ÷ 7 = 3 can be rewritten as [tex]\frac{21}{7} =3[/tex]
Using algebra we know if we multiply 7 onto both sides we end up with
7*3=21
3.
Combined total of 16 fumbles
8 players
Same amount of fumbles
How many fumbles per player?
I would draw this out. You have 8 players and 16 fumbles to allocate to them. You can draw tallies and allocate them to each player. You'll find that the first time they all have the equal amount is when they all have 1 fumble. The next time they all have an equal amount they'll have 2 per and all 16 will be used.
4. Algebra
[tex]\frac{x * 7 - 2}{6} =9[/tex]
First is multiplication: x*7 = 7x
[tex]\frac{7x - 2}{6} =9[/tex]
Then division: Multiply the 6 over because we don't like fractions
[tex]{7x - 2} = 54[/tex]
Next we add the 2 over
[tex]{7x } = 56[/tex]
Then divide by 7 to solve for x
x=8

Answer:
y = -3x + 5)
Step-by-step explanation:
We see immediately that the line crosses the y-axis at (0, 7). The line also goes through (4, -5). As we move from the first to the second point, x increases by 4 and y decreases by 12. Thus, the slope of this line is m = -12/4, or m = - 3.
Using the slope-intercept form,
y = -3x + 5)
Answer: y=3x+7
Step-by-step explanation: You need to remember y=mx+b. M is the slope and b is the y intercept. The y intercept is easy as it's were the line touches the y axis or in this case 7. The slope is rise over run meaning you find a point on the graph like (2,1) and you count how many spaces up until your next to a point, and then you see how many spaces you have to move over or run. In this case you rise 3 and run 1 meaning the slope is [tex]\frac{3}{1}[/tex] or just 3.

Solve Similar Triangles (advanced)
Solve for X.
Given:
[tex]m\angle B=90^\circ, m\angle D=90^\circ, AB=6, BD=4, BC=2, DE=x[/tex].
To find:
The value of x.
Solution:
In triangles ABC and ADE,
[tex]\angle B\cong \angle D[/tex] (Right angles)
[tex]\angle A\cong \angle A[/tex] (Common angles)
[tex]\Delta ABC\sim \Delta ADE[/tex] (AA property of similarity)
We know that the corresponding sides of similar triangles are proportional. So,
[tex]\dfrac{AB}{AD}=\dfrac{BC}{DE}[/tex]
[tex]\dfrac{6}{(6+4)}=\dfrac{2}{x}[/tex]
[tex]\dfrac{6}{10}=\dfrac{2}{x}[/tex]
[tex]\dfrac{3}{5}=\dfrac{2}{x}[/tex]
On cross multiplication, we get
[tex]3\times x=5\times 2[/tex]
[tex]3x=10[/tex]
[tex]x=\dfrac{10}{3}[/tex]
Therefore, the value of x is [tex]\dfrac{10}{3}[/tex] units.
A travel guide has dimensions 8 in. by 10 in. What scale factor should be used to make an enlarged version that has dimensions 12 in. by 15 in.
The scale factor for the length is 12/8 = 1.5 and the scale factor for the width is 15/10 = 1.5
So the scale factor used to make an enlarged version is 1.5.
What is the scale factor?A scale factor is a value used to multiply the dimensions of an object in order to increase or decrease its size. It is often represented as a ratio, such as 1:2 or 1/2, which indicates that the new object is half the size of the original object. Scale factors can also be expressed as a decimal or a percentage, such as 0.5 or 50%. Scale factors can be used in various fields such as architecture, cartography, and graphic design.

What is an equation?
A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.
Given that the fare on bus is $3 per mile.
The taxi fare of taxi is $4. 00 plus $1. 00 per mile.
Assume that at x miles both fare will be the same.
The fare for x miles in bus is $3x.
The fare for x miles in taxi is $4 + $x
Equate to the fares:
3x = 4 + x
Subtract x from both sides:
3x - x = 4
2x = 4
Divide both sides by 2:
x = 4/2
x = 2.
The fare for 2 miles in bus is $3×2 = $6.

Find the measure of MN
Answer:
The measure of arcMN is 60°
Step-by-step explanation:
All the way around the circle is 360°. Two marked arcs are 100° and 140°. AngleMON and AngleNOP are marked equal, which means that ArcMN and ArcNP are also equal. So we can write an equation:
100+140 + x+x =360
combine like terms.
240 + 2x = 360
subtract 240.
2x = 120
divide by 2
x = 60
ArcMN is 60°

Answer:
For function, every element of the domain must have a unique image in co-domain...
(A)Let us redefine each function as a set of ordered pairs
and see if they satisfy the above condition (A) of a function f1={(1,2),(2,3),(3,4)} ; (4,5) cannot be an ordered pair as 5 does not belong to co-domain , Thus the element 4 of domain does not have an image.
f2={(1,4),(2,3),(2,4),(3,2)(3,3),(3,4),(4,1),(4,2),(4,3),(4,4)}
The uniqueness is violated as the elements have not one but many images.
f3={(2,1),(3,2),(3,1),(4,1),(4,2),(4,3)} Not a function as in f2 uniqueness is violated.
f4={(1,4),(2,3),(3,2)(4,1)} It is a function as each element has a unique image.
Brian has 64 flowers for a big party decoration. In addition, he is considering buying flower arrangements that have 18 flowers each. All of the arrangements cost the same. Brian can buy up to 5 arrangements given the amount of money he has. Let x represents the number of flower arrangements Brian buys. Write a function rule to describe how many flowers Brian will have based on the number of arrangements he buys. Find a reasonable range for the function.
The function which can which can define the number of flowers in the arrangement is f(x) = 64 + 18x. The domain is found to be [ 0 , 5 ] and the range is [ 64 , 154 ].
Let the number of flowers which is to be calculated be x,
now we know that she already have 64 flowers and that each arrangement will have 18 flowers.
Therefore, the number of flowers can be given by the function , f(x) = 64 + 18x.
Now , we know that the maximum number of flowers which she can buy externally is 5 , which means the domain becomes [0,5] .
To find the range we will put the value of domain in the given function.

What is '__ main __'?
In Python, __main__ is the name of the environment where top-level code is run.
We know that in Python, the main function acts as the starting point of execution for any software program.
As we know the program executes only when it runs directly, and if it is imported as a module, then it will not run, the execution of the program starts only when the main function is defined in Python.
__main__ is the name of the top-level scope in which top-level code executes.
Also, all the functions and modules will be executed in the top-level scope __main___ in the interpreter shell.
Using the top-level scope __main__ increases the reusability.

Answer:
b= 8
Step-by-step explanation:
you use Pythagorean theorem to solve this problem
a² + b² = c²
since you already have a and c and you're missing b you rearrange the formula to:
[tex]c^{2}[/tex]-[tex]a^{2}[/tex] = b²
17² - 15² = b²
64² = b²
[tex]\sqrt{64}[/tex] = b
8 = b
Step-by-step explanation:
To find side b use Pythagoras theorem:
Hypotenuse²=Base²+Height ²
17²=B²+15²
289-225=B²
64=B²
√8=B²
So,
8 yards is Side B
Now,
We can use Heron's Formula
√S(S-A) (S-B) (S-C)
Let's find semi perimeter
17+15+8/2
40/2=20
So, S=20
Let A=8,B=15,C=17
√20(20-8) (20-15) (20-17)

Working together, Mary and Trevon can
inflate twenty balloons in 7.34 minutes.
Had he done it alone it would have taken
Trevon 14.1 minutes. How long would it
take Mary to do it alone?
20 balloons in 7.34 minutes? lets do the math! [tex]\frac{20}{7.34\\}[/tex] = 2.73 balloons a minute.
If Trevon took 14.1 minutes, lets do the math, [tex]\frac{20}{14.1}[/tex] = 1.42 balloons a minute, now if we take 2.73, subtract 1.42 from 2.73. 2.73 - 1.42, we get, Drum roll please...................... 1.31 !!! So, with that fact, we get 1.31, so that means Mary would have to blow 1.31 balloons a minute WITH Trevon, now some more math. we take the amount Mary did, 1.31, and the amount of time it took for both, 7.34, we get this problem, 1.31 x 7.34 which equals (yes I'm doing it again) DRUM ROLL PLEASEEEE....................... 9.60!!!!!!!!
