3a+8p=14.5
6a+4p=14

divide second equation by 2
3a+2p=7
times -1 and add to first equatlon

3a+8p=14.5
<u>-3a-2p=-7 +</u>
0a+6p=7.5

6p=7.5
divide both sides by 6
p=1.25

now sub
3a+2p=7
3a+2(1.25)=7
3a+2.5=7
minus 2.5 from both sides
3a=4.5
divide both sides by 3
a=1.5

1 apple=$1.50
1 peare=$1.25

Answer: g(4)= -60

Step-by-step explanation:

You just plug in 4 into the equation

g(4)= 2√4 - (4)³

g(4)= 2√4 - (4)³

g(4)= 2·2 - (64)

g(4)= 4 - 64

g(4)= -60
