Answer:
9y+1=32y+1+54
collect like terms, a symbol changes once it crosses the equal to sign =
9y-32y=1+54-1
-23y=54
divide both sides by -23
-23y/-23=54/-23
-23 will cancel -23 to give y
y=54/-23
y=-2.4 or 2 whole number 8/23
Remark
The average is found by adding the total miles and dividing by the total number of hours.
Average
total distance = 52 + 64 + 49
Total distance = 165 miles
Total time = 1 + 1 + 1 = 3 hours.
Average = total distance/ total time
Average = 165 / 3 = 55 miles per hour.
Answer:
The answer is letter 'J'
Step-by-step explanation:
4(3+5) - 3 x 9^2
4(8) - 3 x 9^2 ← 9 x 9 = 81
16 - 3 x 9^2
16 - 3 x 81
13 x 81
1,053
