Step-by-step explanation:

To find the best equation, we simply substitute the values of a, b, and c into the given equations.

a = 21

b = 5

c = 36

$a=\dfrac{7}{10}b\sqrt{c}$

$21=\dfrac{7}{10}5\sqrt{36}$

$21=\dfrac{7}{10}5(6)$

$21=\dfrac{7}{10}30$

$21=(0.7)30$

$21=21$

Ethan lives 2 5/12 miles from school. Marquis lives 7/12 mile closer to school than ethan. How far does marquis live from school

goblinko [34]

Answer:

1 5/6 miles

Step-by-step explanation:

first, we take the amout ethan lives from school, and turn it into a mixed number

2 5/12 = 29/12

marquis lived 7/12 mile closer

so, we have to subtract that from how far away ethan lives

29/12 - 7/12 = 22/12

22/12 simplified is 1 10/12 or 1 5/6
