Answer:
$90.75
Step-by-step explanation:
103*100=(13.5%+100%)*x
10300=113.5x
x=10300/113.5
x=90.74889868
x=$90.75

-----> equation A
----> equation B
Substitute equation B in equation A and solve for y




Find the value of x

Answer:
Arlo's weight = 52.3 kg
Explanation:
Let Arlo be "x"
Then,
Arlo = x
Bert = x+20 (Because Bert is 20 heavier than Arlo)
Cassie = x+20-5 (Because Cassie is 5 lighter than Bert)
Donnie =
(Because Donnie is half of Bert's weight)
Average = 57
Step by step Calculations:
57 =
(The whole divided by 4 because the total people is 4)
57*4 = x + x + 20 + x + 20 - 5 + 
228 = 3x + 35 + 
228 - 3x - 35 = 
193 -3x = 
2(193 - 3x) = x + 20
386 - 6x = x + 20
386 - 20 = x + 6x
366 = 7x
x = 
x = 52.3 kg (corrected to 3 significant figures)
Therefore Arlo's weight is 52.3 kg
Answer:
10
Step-by-step explanation:
We need to divide 2 3/5 ft by 1/4 ft.
2 3/5 / 1/4 =
= 2 3/5 * 4
= 13/5 * 4
= 52/5
= 10 4/10
Answer: 10
