We can set Charmaine's age as x. If William is 3 years older, than his age would be 3 + x.
Charmaine = x
William = 3 + x
Their ages added up together is 76, and we need to multiply Charmaine's age by 3 and William's age by 2.
3x + 2(3+x) = 76
3x + 6 + 2x = 76
5x = 70
x= 14
Charmaine is 14 years old
William's age is Charmaine's age plus 3.
William is 17 years old.
Answer:
x =
Step-by-step explanation:
Given
y = ← multiply both sides by (5x - 2)
y(5x - 2) = 2x + 3 ← distribute left side
5xy - 2y = 2x + 3 ( add 2y to both sides )
5xy = 2x + 3 + 2y ( subtract 2x from both sides )
5xy - 2x = 3 + 2y ( factor out x from each term on the left side )
x(5y - 2) = 3 + 2y ← divide both sides by (5y - 2)
x =
Answer:
I believe the answer is 80 meters.
Note: I am not sure how to explain this so that it makes sense.
Answer:
190
Step-by-step explanation:
First you have to add 94 +94 and then 5+5 and then you add both totals and your answer is 190.
The unit rate of 200 miles in 4 hours is 50 miles for every 1 hour.
200/4 divided by 4/4 = 50/1
The unit rate of 270 miles in 6 hours is 45 miles for every 1 hour.
270/6 divided by 6/6 = 45/1
The unit rate of 1440 miles in 30 hours is 48 miles for every 1 hour.
1440/30 divided by 30/30 = 48/1
