X + y = 125
x - y = 47
---------------add
2x = 172
x = 172/2
x = 86
x + y = 125
86 + y = 125
y = 125 - 86
y = 39
ur 2 numbers are 39 and 86
Seniorpay=39.50+juniorpay
pay=rate times time
seniorpay=16 times 14=224
juniorpay=18 times x=18x
224=39.50+18x
minus 39.50 from both sides
184.5=18x
divide both sides by 18
10.25=x

Answer:
25 km
Step-by-step explanation:
Distance covered in 20 min = 5 km
Distance covered in 1 min = 5/20 km or 1/4 km.
Distance covered in 100 min =
1/4 km x 100 = 25 km
Part One
The cost of 2 liters is $2.40
The cost of 1 liter = 2.40/2 = 1.20
Part two
1 bottle contains 12 liters
6 bottles contain 12*6 = 72 liters.
All of this comes at a cost of 3.90
The cost is 3.90 / 72 = 0.054 dollars / Liter which is about 5 pennies.
The one with the higher cost is 1.40 dollars / liter. Part One. Answer
17 = 3(4x - 5)
<em><u>Distributive property.</u></em>
17 = 12x - 15
<em><u>Add 15 to both sides.</u></em>
32 = 12x
<em><u>Divide both sides by 12.</u></em>
x = 2.67. (This is your answer.)
