Answer:
4 hours, $60
Step-by-step explanation:
Assuming "d" is equal to the dollars Jacob earned and h= hours, you start by setting the equations equal to each other, since both are equal to "d."
15h=10h+20
Subtract 10h from both sides (to combine like terms) so the equation becomes:
5h=20
Divide 5 from both sides, to isolate "d" :
h=4
The number of hours Jacob worked is 4, as the equation above shows. To find the amount of money Jacob made, substitute 4 as "h" into the two original equations:
d= 15(4) d=$60
d=10(4)+20 d=$60
Jacob earned $60 dollars in 4 hours.
It would be A because b+a

Answer:
fg(5) = 64 and gf(5) = 28
Step-by-step explanation:
Given
f(x) = x²
g(x) = x + 3
Now
fg(5)
= f ( 5 + 3 )
= f( 8)
= 8²
= 64
Also
gf(5)
= g(5²)
= g( 25)
= 25 + 3
= 28
Hope it will help :)
