In order to combine, you have to multiply the top equation by 2 so you get 8g + 10h = 8 8g - 10h = 4 --------------- 16g = 12 g = 3/4 --> plug it in to solve for h 8(3/4)-10h = 4 6-10h=4 10h=2 h=1/5 Your result: g=3/4, h=1/5

Find the rate of change
vesna_86 [32]

Answer:

11

Step-by-step explanation:

The rate of change  is the ratio of the change in Y to the change in X.

When Y changes from -40 to 4, that is an increase of 44 (4--40=4+40=44), so the change in Y is +44.  The corresponding change in X is from -3 to 1, so the change in X is +4 (1--3=1+3=4).  The ratio of the change in Y to the change in X is 44/4=11.

Try doing the same computation going from the second row to the third row and you will get the same ratio of 11.

san4es73 [151]

Answer:

3:2

Step-by-step explanation:

The ratio of boys to girls will be 12:8

But, this can be simplified, since both numbers are divisible by 4.

12/4 = 3

8/4 = 2

So, the simplified ratio of boys to girls is 3:2
