Answer:
B. Start at -7 on the number line and move 11 to the right.
Step-by-step explanation:
<u>Given:</u>
We can add or remove only positive numbers on the number line to get it correct, so we need to open the parenthesis. When evaluated we get:
-7- (-11) = - 7 + 11 = 4
<u>Correct interpretation of of this expression is:</u>
- Start at -7 and add 11, thus move 11 points to the right, to get 4 as final point.
<u>Correct choice is:</u>
- B. Start at -7 on the number line and move 11 to the right.
5(n+6)=48
5n+30=48
5n=18
n=18/5
Distance = speed rate x time
Speed rate = 120 miles per hour
Time = 3 hours
Replacing:
D = 120 mph x 3 h = 360 miles
Two cheaper books = x
more expensive = 1.5x
so, 2.5x=150
150/2.5=x=60
therefore the more expensive book = 90
