Answer:
a = 14
Step-by-step explanation:
<u>Step 1: Write out your problem</u>
f (a) = 5a + 14 | f (a) = 0
<u>Step 2: Solve</u>
f (a) = 5 (0) + 14 , Input a.
f (a) = 0 + 14 , 5 x 0 = 0
(a) = 14 , 0 + 14
a = 14
The answer would be the algebraic expression, b + 9. The
translation here is b is representing the number of blue bikes then you needed
to add the 9 which represents the 9 red bikes. The two is added together, to get
the total of those red and blue bikes which we are looking for.
We can swap the subtraction with addition to find out what ? equals to:
? - 66 = 25.
? = 25 + 66.
? = 91.
Check:
91 - 66 = 25
