First you take the area,

4 x 2 = 8 cm

Then you take 72 cm and divide it by 8 cm to get your length

So the answer for the length is 9 cm

Answer:

$\square\quad{y=\dfrac{1}{2}x+4}\\\\\square\quad{\dfrac{y-5}{x-2}=\dfrac{1}{2}}$

Step-by-step explanation:

The slope of a line is the same everywhere, so an equation can be written making use of that fact.

$\dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}\\\\\dfrac{y-5}{x-2}=\dfrac{7-5}{6-2}=\dfrac{2}{4}\\\\\boxed{\dfrac{y-5}{x-2}=\dfrac{1}{2}}$

Cross-multiplying gives ...

2(y -5) = x -2

2y -10 = x -2 . . . eliminate parentheses

2y = x +8 . . . . . . . add 10; next, divide by 2

$\boxed{y=\dfrac{1}{2}x+4}$

These equations match choices B and D.

If you work 40 hours per week at $13.00 per hour and save 10% of your gross earnings, how much will you save per week?

Vesna [10]

You work 40 hours per week and make 13$ per hour, so multiply 40 and 13 and you get how much you make a week. Then find out what 10% of that number you got is and you get your answer.

You should get: 52$
