Drag the tiles to the correct boxes to complete the pairs.
Match each solution to the equation it solves.
Answer:
the first one is 3
the second one is 7
the third one is -2
and the last one is -3
Step-by-step explanation:
The equation is matched with its solutions below;
1/4x + 5/3x - 4 = 2 - 1/12x; x = 33.2b - 4.7 = 3b - 3.3; b = 74.6y - y + 4 = y - 1.2; y = -27.5c - 2.5c + 8 = - 7; c = -3What is the solution to the equation?1/4x + 5/3x - 4 = 2 - 1/12x
combine like terms
1/4x + 5/3x + 1/12x = 2 + 4
(3x+20x+x) / 12 = 6
24/12x = 6
2x = 6
Divide both sides by 2
x = 6/2
x = 3
3.2b - 4.7 = 3b - 3.3
combine like terms
3.2b - 3b = -3.3 + 4.7
0.2b = 1.4
divide both sides by 0.2
b = 1.4 / 0.2
b = 7
4.6y - y + 4 = y - 1.2
combine like terms
4.6y - y - y = - 1.2 - 4
2.6y = - 5.2
divide both sides by 2.6
y = -5.2 / 2.6
y = -2
7.5c - 2.5c + 8 = - 7
5c = -7 - 8
5c = -15
divide both sides by 5
c = -15/5
c = -3

⭐️ I NEED HELP ASAP: Sam and Joe are brothers. Joe is five less than three times the age of Sam. If the product of their ages is 28, how old are Joe and Sam?
Please explain how you solved it too! Thank you!
Answer:
joe=6
Sam=11
Step-by-step explanation:
lets see...
i explain 1by1
firstly we know that joe is 5 - 3 x Sam
(read the sentences VERY CAREFULLY)
then, we put Sam as math variable "s"
it will be; 5-3 x S
[tex]5 - 3 \times s[/tex]
the total of their age is 28
[tex]5 - 3 \times s = 28[/tex]
simplify it
it will be 5-S3=28
then you will get 11 right
that will be sam's age
-5 and it will be Joe's age

PLZ HELP ASAP.....Your dad is researching landscaping companies to come put new mulch out for the year. The first company charges $100 just to come out, plus $10 per bag of mulch, m, needed. The second company doesn’t charge to come out but charges $30 per bag of mulch. After how many bags of mulch will the total cost of each company be the same?
Answer: After 5 bags of mulch, the cost for both companies will be the same.
Step-by-step explanation:
The cost for Company can be represented by the equation: y= 10m+100
The cost for Company B can be represented by the equation: y= 30m
To find the amount of mulch, their cost needs to be the same, I will solve for m
10m+100=30m
-10m 10m
100=20m
Divide both side by 20
100/20=20m/20
5=m or m=5
So after 5 bags of mulch, the total cost for both companies is the same.

What is the answer of question 17 in lesson 2.1 translations
9514 1404 393
Answer:
y = 2x(1, 2)Step-by-step explanation:
The line representing Murphy street goes through point (0, 3) and has a slope of 2/1 = 2. Its equation is then ...
y = mx + b
y = 2x +3
The translation vector transforms this equation* by adding -1 to y, and replacing x with x-1.
y = (2(x-1)) +3) -1
y = 2x -2 +3 -1 . . . . eliminate parentheses
y = 2x . . . . . . . . . . . the equation for Nolan street
__
Of course, adding (1, -1) to the point (0, 3) moves it to ...
(1, -1) +(0, 3) = (0+1, -1+3) = (1, 2)
The image of (0, 3) is (1, 2).
_____
* f(x) is translated by (a, b) this way: g(x) = f(x-a) +b. Here, f(x) = 2x+3 is translated to f(x-1)+(-1) = (2(x-1) +3) -1.
Omari and his two cousins received the same amount of money to go to the movies. Each boy spent $15. Afterward, the boys had $30.75 altogether. How much money did each boy receive?
Answer:
Each boy recieved $25.25 each
Step-by-step explanation:
First, you add up all the money the 3 boys spent.
15+15+15=45
Then you add the sum of the equation to the amount all the boys had afterward.
45+30.75=75.75
Finally, you divide that product to 3 boys.
75.75/3=25.25
Therfore the answer is $25.25 each.

8y + 7x = 9 for x
Answer:
x = 9-8y/7
Step-by-step explanation:
8y+7x=9
Subtract 8y from both sides.
7x=9−8y
Divide both sides by 7.
7x/7 = 9 - 8y/7
Dividing by 7 undoes the multiplication by 7.
x = 9-8y/7

Which set of numbers could represent the lengths of the sides of a right triangle?
Answer:
number 4: 8, 15,17
Step-by-step explanation:
This is all just the theorem that a^2+b^2=c^2 so I tried that for all of them and number 4 is the only one that ends as a whole number. Sorry, that wasn't the best explanation but I hope you understood. Just try the theorem on each one like 4(2^2)+9(3^2) doesn't equal 16(4^2)
Triangle ABC has the coordinates A(-3, -2), B(2, 4) and C(2,-2). What is the area of triangle ABC?
square units
Answer: The area is 15 square units
Step-by-step explanation: It is helpful to sketch the coordinates on a graph to get an idea of what the triangle looks like so you can see which side will be the base, and where to get the height. You will see that AB is the hypotenuse, it is a right triangle, so AC can be the base and BC is the height.
Use the differences in x-values of points C & A to get the length of the base: 2-(-3) is 5
Use the differences in y-values of points B & C to get the height:
4-(-2) = 6
Area = bh/2
A = 5×6/2 = 30/2
A = 15 square unts
