Solve the equation 7h-5(3h- 8) = -72
Anon25 [30]

Answer: h=14


Step-by-step explanation:

7h-5(3h-8)=-72

7h-15h+40=-72 > I distributed the -5(3h-8) to get rid of parenthesis

-8h+40=-72 > I combined the like terms 7h-15h

-8h=-112 > I subtracted 40 from both sides

h=14 > I divided -8 from both sides

Steve has three times as many quarters as half-dollars. The coins total $13.75. How many total coins does he have, how would you
statuscvo [17]
Hello,
Let assume x the number of half-dollars3x is the number of quarters.
The coins total $13.75.
0.50 *x+ 0.25 *3x=13.75\\

\Rightarrow\  \dfrac{x}{2}+ \dfrac{3x}{4}=13.75\\

\Rightarrow\  \dfrac{2x}{4}+ \dfrac{3x}{4}=13.75\\

\Rightarrow\  \dfrac{5x}{4}=13.75\\

\Rightarrow\  5x=4*13.75\\

\Rightarrow\  5x=55\\

\Rightarrow\  x=11\\



11 is the number of half-dollars

33 is the number of quarters.
