Vanessa has 23 coins in nickels and dimes and has $1.50 in all. Which equation could be used to find the number of
nickels, n?
A. 5n + 10 (23) = 1.50
B.5n + 10 (23 – n) = 1.50
C. 0.05%+0.10 (23 – 1) = 1.50
D. 0.05m+0.10 (m - 23) = 1.50

answer: 30

step-by-step explanation: its 30 because im a basketball player and stephen curry hits most of his shots so if you put 30 you might make the shot goodluck

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.

3 4 7 12 19

+1 +3 +5 +6

i would guess 26 because this isnt a sequential pattern or its to short to know

the answer is that it is true
