Answer:

x=6

Step-by-step explanation:

6(2x -11) 15 =21

6 × 2x = 12x

6 × -11 = -66

12x -66 + 15 = 21

-66 + 15 = -51

12x -51 = 21

-51 + 51 = 0

21 + 51 = 72

12x = 72

12x ÷ 2 = 0

72 ÷ 12 = 6

x = 6

A supplier sells 2 and 1/4 pounds of mulch for every 1 and 1/3 pounds of gravel. The supplier sells 172 pounds of mulch and grav

polet [3.4K]

Because ratios can be written as fractions
$\frac{mulch}{2.25}=\frac{gravel}{1.33}$

172 = $\frac{mulch}{2.25}+ \frac{gravel}{1.33}$
172 - $\frac{mulch}{2.25}$ = $\frac{gravel}{1.33}$
76.44 mulch = x amount of gravel = 172
Gravel = 172 - 76.44
= 95.56
