10 + 3(5n - 12) = 13n
10 + 15n - 36 = 13n
15n - 13n = 36 - 10
2n = 26
n = 13 [Answer C]

10+3(5n-12)=13n
Distribute:
10+15n-36=13n
Add like terms:
-26+15n=13n
Subtract 15 on both sides:
-26=-2n
Divide by -2 on both sides:
13=n (c)
Hope it helps!

The Ms Jodi has 950 non fiction books. 40% of those books are about science topics and 30% are about history. How many books are
Bad White [126]

Step-by-step explanation:

well first you need to divide all the percents by 100.

40% = .40

30%= .30

and now you need to multiply those two by 950.

.40/950=4.20

.30/950=3.15

so ms jodi has about 3 books on history
