1 answer:

4 0

-(9x+12)=-8x-(x+3)
-9x-12= -8x-x-3
-9x+9x=9
-9

if u look at the eq for x it has no value. but if u r asking a solution for a eq then it is -9

Answer:

$\frac{5}{7}\div \frac{7}{10}=\frac{50}{49}$

Step-by-step explanation:

$\frac{5}{7}\div \frac{7}{10}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}$

$=\frac{5}{7}\times \frac{10}{7}$

$\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}$

$=\frac{5\times \:10}{7\times \:7}$

$\mathrm{Multiply\:the\:numbers:}\:5\times \:10=50$

$=\frac{50}{7\times \:7}$

$\mathrm{Multiply\:the\:numbers:}\:7\times \:7=49$

$=\frac{50}{49}$

Therefore,

A: 38.4 - 25 = 13.4
13.4 + 32.65 = $46.05

B: 50.15 - 32.65 = 17.5
17.5 + 25 = 42.5 mph
