Answer:
d
Step-by-step explanation:
155$ after 3 months means 45$ less. 45$ divided by 3 (the number of months) =15
that means she spends 15$ per month
Answer:
( f o f )(x) = f ( f (x))
= f (2x + 3)
= 2( ) + 3 ... setting up to insert the input
= 2(2x + 3) + 3
= 4x + 6 + 3
= 4x + 9Step-by-step
explanation:
X =10.
First distribute the 2(2x-14) and get 4x-28.
x+2-4x-28. Subtract x from each side to get 2=3x-28.
Add 28 to both sides to equal 30=3x. Divide each side by 3 to get your final Answer, x=10.
L = w+22
2(l+w) = 4040
2(w+22+w) = 4040
2w + 22 = 4040/2 = 2020
2w = 2020-22 = 1998
w = 999ft
l = w+22 = 999+22 = 1021ft
w = 999 ft
Answer:
Step-by-step explanation:
d + q = 94.....d = 94 - q
0.10d + 0.25q = 19.30
0.10(94 - q) + 0.25q = 19.30
9.4 - 0.10q + 0.25q = 19.30
-0.10q + 0.25q = 19.30 - 9.40
0.15q = 9.90
q = 9.90/0.15
q = 66 <===== there are 66 quarters
d + q = 94
d + 66 = 94
d = 94 - 66
d = 28 <==== there are 28 dimes
