-83 + -30<br> Integers…………….

anastassius [24]

Answer:

-113

Step-by-step explanation:

Let's use the Decomposition Method.

1) Use this rule: $-a-b=-(a+b)$ .

$-(83+30)$

2) Use the decomposition method.

$83 = 80 + 3$

$30 = 30 + 0$

_____________________

$110 + 3 = 113$

3) After simplification, we have:

$-(83+30)=-113$

4) Therefore, $-83-30=-113$ .

$-113$

The coordinates on a map for City A are (57, 11) and those for City B are (121, 79). Note that coordinates represent miles. Find

Juliette [100K]

Answer:

93 miles

Step-by-step explanation:

Use the distance formula:

d = $\sqrt{(x2 - x1)^2 + (y2 - y1)^2}$

Plug in the values:

d = $\sqrt{(121 - 57)^2 + (79 - 11)^2}$

d = $\sqrt{4096 + 4624}$

d = $\sqrt{8720}$

d = 93.4

= 93 miles

Write a real world problem that you would represent with the equation 4x+5=37.

AURORKA [14]

Bob was 5 feet off the ground. He travels 4 feet every single second. How long will it take for him to reach 37 feet?

4x + 5 = 37

4x + 5 (-5) = 37 (-5)

4x = 32

4x/4 = 32/4

x = 8

It will take Bob ~8 seconds to reach 37 feet*
