Answer:
cm³
Step-by-step explanation:
The rate is about 72 and 2/3 miles per gallon
Let x = the number of boxes they need to sell to get to 180
(1 1/8) * x + 75*(1 1/8) = 180 There's a number of ways you could solve this. I think the easiest way (or the easiest to explain) is to start by converting 1 1/8 to a decimal
1/8 = 0.125
1 1/8 = 1 + 0.125
1 1/8 = 1.125 Put this result in the equation.
1.125x + 75 * 1.125 = 180
1.125x + 84.375 = 180 Subtract 84.375 on both sides.
1.125x = 180 - 84.375
1.125x = 96.625 Divide by 1.125
x = 96.625 / 1.125
x = 85
They must sell 85 more boxes to raise 180 dollars.
Answer:
a - 8
Explanation:
7a−6+3−8a−(−2a+5)
Distribute the Negative Sign:
=7a−6+3−8a+−1(−2a+5)
=7a+−6+3+−8a+−1(−2a)+(−1)(5)
=7a+−6+3+−8a+2a+−5
Combine Like Terms:
=7a+−6+3+−8a+2a+−5
=(7a+−8a+2a)+(−6+3+−5)
=a + −8
Answer:
= a − 8
