Answer:

<em>A. (1, 2)</em>

Step-by-step explanation:

8x+4y=16  

7y=15-x

Divide both sides of the first equation by 4.

2x + y = 4     Eq. 1

Solve 2nd equation for x.

x = 15 - 7y

Substitute x of Eq. 1 with 15 - 7y.

2(15 - 7y) + y = 4

30 - 14y + y = 4

30 - 13y = 4

-13y = -26

y = 2

Substitute 2 for y in Eq. 1.

2x + 2 = 4

2x = 2

x = 1

Solution: (1, 2)

Answer: A. (1, 2)

how many times as much is the number of students at Pengrove university has the number of students at Allentown College?
svp [43]
The answer would be: D-100. The reasoning of this is because if you take 3 X 10 to the third power and did the exponent (10 to the third power in this case) and multiplied it you would obviously get 1,000 for an answer. Then would would do 1,000 X 3 to get 3,000.
