135 x 0.65 =87.75
so the answer
should be
87.75
Answer:
1. x=69/40
2. x=3/4
Step-by-step explanation:
#1 steps
1. Convert the decimals to fractions
x/9/20 = 23/100/3/50
2. Simplify the fractions
20x/9 = 23/6
3. Simplify the equation using cross multiplication
6 * 20x = 23 * 9
120x = 207
4. Divide both sides by 120
x = 69/40
#2 steps
1. Simplify the fractions
1/3/1/6 = 3/2/x
2 = 3/2/x
2 = 3/2x
2. Multiply both sides by the equation 2x
4x = 3
3. Divide both sides by 4
x = 3/4

Answer:
Step-by-step explanation:
For l laps around a 1/4 mile track, the total distance is ...
l×(1/4)
After adding 2 1/2 miles to that, Gabriella's total distance was 4 miles:
l×(1/4) +(2 1/2) = 4 . . . . an equation to find l
__
We can solve this equation by subtracting 2 1/2, then multiplying by 4.
l×(1/4) = 1 1/2
l = 4(1 1/2)
l = 6
Gabriella ran 6 laps on the track.
Answer:
C
Step-by-step explanation:
$101 times 6 is $606...
convert both dimensions to feet
1 mile = 5280 feet so 1/2 mile = 5280/2 = 2640 ft
1 yard = 3 ft so 600 yards = 600*3 = 1800 feet
now calculate area = 2640*1800 = 4752000 square feet
acres = square feet / 43560 so 475200/43560 = 109.09 acres
