Question

Solve the equation. Then check your solution. Negative 65.376 = 7.2 (9 c + 1) a. 1.12 b. –0.9 c. –1.12 d. –1.02

Answer 1

Answer:

$c=-1.12$

Step-by-step explanation:

$7.2\left(9c+1\right)=-65.376$

$\frac{7.2\left(9c+1\right)}{7.2}=\frac{-65.376}{7.2}$

$9c+1=-\frac{227}{25}$

$9c+1-1=-\frac{227}{25}-1$

$9c=-\frac{252}{25}$

$\frac{9c}{9}=\frac{-\frac{252}{25}}{9}$

$c=-\frac{28}{25}$

$c=-1.12$
