Answer:

x = -10

Step-by-step explanation:

expand

simplify 36 - 4.5x + 36 to -4.5x + 72

simplify 102 - 7.5x - 60 to -7.5x + 42

add 7.5x to both sides

simplify -4.5x + 72 + 7.5x to 3x + 72

subtract 72 from both sides

simplify 42 - 72 to -30

divide both sides by 3

simplify 30/3 to 10

Answer: x = -10

Answer:

$\frac{7}{8} \div \frac{1}{2} = \frac{7}{4}$

Step-by-step explanation:

Here we are given four equations and we have to find the equation that gives the number of half inches that are in $\frac{7}{8}$ inches.

To find how many half inches i.e. $\frac{1}{2}$ inches are there in $\frac{7}{8}$ inches we have to divide $\frac{7}{8}$ by $\frac{1}{2}$ .

So, the equation that will give the result is $\frac{7}{8} \div \frac{1}{2} = \frac{7}{8} \times \frac{2}{1} = \frac{7}{4}$ (Answer)
