-a+7=2a-8
-a+a+7=2a+a-8 add a on both sides
7+8=3a-8+8 add 8 on both sides
15/3=3a/3 divide 3 on both sides
a=5 solution

Step-by-step explanation:
Answer:
177 pounds
Step-by-step explanation:
Create an equation to represent the system.
Since it's 18% more than what was used last month an equation can be written such as the one below:
(118%)( last month's cheese ) = this month's cheese
Convert the percentages into decimals by moving the decimal place at the end of 118.00 two places to the left
118% = 1.18
( 1.18 )( last month's cheese ) = this month's cheese
Next, plug in the number for last month's cheese
( 1.18 )( 150 pounds) =
177 pounds
Distance between Los Angeles and San Francisco = 385 miles
So , if we have to locate 385 miles on the map taking the scale
1 inches = 15 miles
1 miles =
inches
so, 385 miles = 
→→385 miles = 25.67 (approx)
Option (B) is correct.
Yes it is true that a small deviation means the data set tended to cluster around the mean .
