The mistake is made in the second step. The correct steps are given below.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Wilma estimates that she’ll drive about 18,000 miles during the year.
The car she wants to purchase gets an average of 24 miles per gallon, and the average cost per gallon of gas in her neighbourhood is $2.72.
Locate the error in her calculations, and select the correction.
Step - 1
18000 miles/year
18000 miles / 12 months = 1500 miles/month
Step 2
1500 miles/month
1500 miles/month / 24 miles per gallon = 62.5 gallons/month
62.5 gallons/month
Step 3
(62.5 gallons/month) x ($2.72/gallons) = $170 cost/month

SA=2(3)(3)+(3)(3)+(3)(3)
Explanation: the formula for SA for a rectangular prism is SA=2(wl+hl+hw)
Answer:
Step-by-step explanation:
The rate of production is 540 per 0.5hr=>1080 per hour.
Let t be the number of hours. We convert the times in hours only(1 hr=60mins)
- 3hrs 30 mins=3.5hrs
- 5hrs 15mins=5.25hrs
- 8grs 45 mins=8.75hrs
#We therefore multiply directly to find the number of cups after t hours:
Step-by-step explanation:
A=D+qm
qm = A - D
q =(A-D) /m
