Answer:
Yes
Step-by-step explanation:
If you add 87.84, 85, and 100 you get 272.84. Once you divide that by 3 you get 90.946, which would be your test average if you score 100 on your next test.
Answer:
so I believe we can do 15% of 45, so that is 6.75.
so now we do:
45.00
<u>+ 6.75</u>
<u><em>51.75 is your answer!</em></u>
please mark brainliest if correct!

Evaluate f(g(3)).
g(3) = 3^2 -4 = 5 so
f(g(3)) = f(5) = 3*5-2 = 15 -2 = 13
Thank you,

Answer:
Joseph's present age=3 yrs
David's present age=9 yrs
Step-by-step explanation:
Let Joseph's present age be x.
David's present age=3x
__________________
Ater 3 yrs,
Joseph's age=x+3
David's age=2(x+3)
Also, we can add 3 to David's present age to get age After 3 yrs. So, David's age after 3 yrs would also be 3x+3.
Now, balance them.
3x+3=2(x+3)
3x+3=2x+6
x=3
D"s prsent age=9
J's present age=3
