Answer:

1. a. draw 5 boxes with 7ś in them and x=7

2. number 7. x+x+x=9 that is A. and x+3=9 for B.

3. part a: x+9=16 draw a box with x+9=16 and x=7

3. part b: 4(x)=28 draw a bout that matches that and x=7

Step-by-step explanation:

1. the value of x is seven because 5x = 35 divide x on both sides is 7

2. number 7. x+x+x=9 that is A. and x+3=9 for B.

3. part a: x+9=16 draw a box with x+9=16 and x=7

3. part b: 4(x)=28 draw a bout that matches that and x=7

The number of yards in 50 feet of the standard fire hose will be 16.67 yards.

Unit modification is the process of converting the measurement of a given amount between various units, often by multiplicative constants that alter the value of the calculated quantity without altering its impacts.

A standard fire hose is 50 feet long.

The conversion formula is given below.

1 yard = 3 feet

The number of yards in 50 feet is calculated as,

⇒ 50 / 3

⇒ 16.67 yards

Answer:

If something is a function, every x-value, only has one (1) y-value. If the line x = 0 intersects the graph in two points, there are to values for y (instead of one). Therefore the graph is not a function of x.

Your answer is A.

Step-by-step explanation:

Answer:

it would be positive 54

Step-by-step explanation:

Pls do not think my answer is correct im just guessing

Step-by-step explanation:

• x + (x+1 )+(x+2)= -54 so we have three x's and the sum of 2 and 1 =3

=> 3x+3=-54

=> 3x=-54-3

=> 3x=-57 divide -57 for 3

=> x=-19

=> x+1= -19+1 = -18

=> x+2= -19+2=-17

there fore the three consecutive integers are -19,-18,-17

-19+-18+-17=-54

Answer:

Step-by-step explanation:

whole numbers are the numbers 0 to +∞ (not including fraction, numbers i.e 6.89 etc)

integers are the numbers -∞ to +∞ (not including fraction, decimal numbers i.e -5.57, 7.74 etc)

since integers are the numbers including whole numbers thus the statement is true

Natural numbers are the numbers 1 to +∞ (not including fraction, decimal numbers i.e 6.89 etc)whereas whole numbers are the numbers 0 to +∞ (not including fraction, numbers i.e 6.89 etc)

hence, the statement is true

All Whole numbers are integers but not all integers are whole numbers

therefore, the statement is not true

the given definition is the perfect definition of rational numbers

hence, the statement is true

A. All whole numbers are integers.

[tex]\boxed{True}[/tex]

➺ Whole numbers include numbers from 0 to above. Integers include all numbers (negative & positive ones). Hence, all whole numbers are integers.

____________________

B. All natural numbers are whole numbers.

[tex]\boxed{True}[/tex]

➺ As said above, whole numbers include numbers from 0 to above. Natural numbers on the other hand include numbers from +1 to above (right side of the number line). So, all natural numbers come under whole numbers.

____________________

C. All integers are whole numbers.

[tex]\boxed{False}[/tex]

➺ Integers include both negative & positive numbers while whole numbers only include numbers from 0 to above (right side of the number line). Since, negative numbers don't come under whole numbers, integers can't be categorised as whole numbers. •°• All integers are not whole numbers.....but all whole numbers are integers.

____________________

D. All fractions of form [tex]\frac{p}{q}[/tex], where p and q are integers and q [tex]\neq[/tex] 0, are rational numbers.

[tex]\boxed{True}[/tex]

➺ This is the definition of rational numbers. All fractions are under rational numbers, so this definition stands true for fractions as well.

____________________

[tex]\large\underbrace{ \overbrace{ \mathfrak{Answer}}}[/tex]

⟹ So, the statement which doesn't match or is NOT true will be ➳ C. All integers are whole numbers.

Answer:

24

Step-by-step explanation:

you find area of a triangle with equation:

[tex] \frac{1}{2} bh[/tex]

base: 6

height: 8

[tex] \frac{1}{2} (6)(8)[/tex]

[tex] \frac{1}{2} (48)[/tex]

area equals: 24

for the second photo

vertex would be at (1,-8)

this is because each vertex is in a different quadrant so you would need a negative y axis to form the rectangle

=========================================================

Explanation:

It might help to draw out a diagram. Refer to the image below. Point A is the cell tower location. Point B is where the person is located. This is a birds eye view. Point B is on the smaller circle of radius 23 ft. The cellphone, which has unknown location, is somewhere on the larger circle of radius 47 ft.

The best case scenario is that the phone is on ray AB, which would make the phone to be 47-23 = 24 ft away from the person. This is the closest the phone could be.

------------------

Extra info:

On the flip side, the worst case scenario is that the phone is on the diametrically opposite side. This would mean the distance from the phone to the person is 47+23 = 70 ft. So the range of possible distances d is [tex]24 \le d \le 70[/tex]

Answer:

3 degrees F

Step-by-step explanation:

-4 + 7 = 3

The temperature at 5:00pm was -4°F. The temperature rose (it means adding) 7°F once the sun came up at 8:00am.

Write an addition expression.

(-4)+(+7)

-4+7

+3

(The answer is positive because it matches the sign of 7, the numerically larger number)

Therefore, the temperature was 3°F.

Answer:

t=100-s

Step-by-step explanation:

Since we know T as the total amount, we need to figure out how much was spent from the $100 Julie has. She can't gain more money magically so you have to take away from the 100. The amount taken away is the S (a.k.a- how much was SPENT). After putting that together, you get t=100-s.
