Hello from MrBillDoesMath!
Answer:
15
Discussion:
Given: measure angle STQ = 7x + 55.  But, as shown, STQ is a right angle so
7x + 55 = 90          => subtract 55 from each side
7x = 90 -55 = 35   => divide each side by 7
x = 35/7 = 5
Since RS = (x+1)    + (2x-1)  where x = 5.
      RS = (5 + 1) + (2*5 -1)
            = 6         + 9
            = 15
I don't know what choice the answer is as your diagram only shows Choice A
Thank you,

Answer:
$84
Step-by-step explanation:
Find how many miles she traveled by multiplying 80 and 2.
80 × 2 = 160 miles
Next find out how much she gets paid for her mileage by multiply $0.60 and 160.
160 × $0.60 = $96.00
Now find out how much she spent on gas. She gets 40 miles per gallon so solve how many gallons she used by dividing 160 by 40.
160 ÷ 40 = 4 gallons
Then multiply 4 gallons by $3.00
4 × 3 = $12
To find the net rate of pay subtract 96 and 12
$96 - $12 = $84

Step-by-step explanation:
1. mode is the value which appears most 
mode = 12
median is the value in the 
middle
median = 14
2. mode = 12
median = 14
