Fynjy0 [20]

Answer:

(-7, -10)

$x=-7\\y=-10$

Step-by-step explanation:

$4x-4y=12$

Substitute x for -7.

$4(-7)-4y=12$

Multiply 4 by -7.

$-28-4y=12$

Add 28 on both sides.

$-4y=40$

Divide -4 on both sides.

$y=-10$

Fynjy0 [20]

Given:

Last year 80 students signed up for a summer trip to Washington, D.C.

This summer 50 students have signed up to go.

To find:

The percent decrease in the number of students.

Solution:

We have,

Students in last year = 80

Students in this year = 50

Now,

$\text{Decrease}\%=\dfrac{\text{Students in last year - Students in this year }}{\text{Students in last year }}\times 100$

$\text{Decrease}\%=\dfrac{80-50}{80}\times 100$

$\text{Decrease}\%=\dfrac{30}{80}\times 100$

$\text{Decrease}\%=\dfrac{3}{8}\times 100$

$\text{Decrease}\%=37.5$

Therefore, the correct option is B.
