Sladkaya [172]

Answer:

$Mike\ Chewer = 14\frac{1}{2}\ hr$

$Jennifer\ Glass = 3\frac{3}{4}\ hr$

$Fred\ Carlton = 1\frac{1}{4}\ hr$

$Amy\ Amaretto = 12\ hr$

Step-by-step explanation:

Given

$Mike\ Chewer = 870\ minutes$

$Jennifer\ Glass = 225\ minutes$

$Fred\ Carlton = 75\ minutes\\$

$Amy\ Amaretto = 720\ minutes$

Required

Convert to hours (in fraction)

To do this, we simply divide the time by 60

$Mike\ Chewer = 870\ minutes$

Divide by 60

$Mike\ Chewer = \frac{870}{60}\ hr$

$Mike\ Chewer = \frac{87}{6}\ hr$

Express as mixed numbers

$Mike\ Chewer = 14\frac{3}{6}\ hr$

Simplify

$Mike\ Chewer = 14\frac{1}{2}\ hr$

$Jennifer\ Glass = 225\ minutes$

Divide by 60

$Jennifer\ Glass = \frac{225}{60}\ hr$

Express as mixed numbers

$Jennifer\ Glass = 3\frac{45}{60}\ hr$

Simplify

$Jennifer\ Glass = 3\frac{3}{4}\ hr$

$Fred\ Carlton = 75\ minutes\\$

Divide by 60

$Fred\ Carlton = \frac{75}{60}\ hr$

Express as mixed numbers

$Fred\ Carlton = 1\frac{15}{60}\ hr$

Simplify

$Fred\ Carlton = 1\frac{1}{4}\ hr$

$Amy\ Amaretto = 720\ minutes$

Divide by 60

$Amy\ Amaretto = \frac{720}{60}\ hr$

$Amy\ Amaretto = 12\ hr$

Solve each of these equations. Explain or show your reasoning.

Svetlanka [38]

$2(x+5)=3x+1 \\2x+10=3x+1 \\-x=-9 \\x=9$

$3y-4=6-2y \\5y=10 \\y=2$

$3(n+2)=9(6-n) \\3n+6=54-9n \\12n=48 \\n=\frac{48}{12}=4$

Hope this helps.
