Answer:
8
Step-by-step explanation:
8y-3y=40
5y. = 40
y. =8
the value of y is 8.
...
3x - 6x + 14 = 2x + 39
-3x + 14 = 2x + 39
-5x = 25
x = -5
This is 60 because if you were to 12 times 1 you would get 12 then multiply by 5 and you get 60. Now to check your answer do 12 divided by 12 which gives you 1 and do 60 divided by 12 gives u 5. Therefore the answer is 60cm hope this helps!
Anzelm wants to burn 540 calories while jogging. Jogging burns about 12 calories per minute.
he usually plans to stop and rest for about 5 minutes.
m represents the total minutes.
12 calories per minute.
for m minutes the calories burn is 12m
He stop and rest for about 5 minutes. so we need to subtract 5 from total minutes
So expression becomes 12(m-5)
He wants to burn 540 calories. So we set the calories = 540
The equation becomes ,
12(m-5) = 540
Now we solve for m , total number of minutes
12(m-5) = 540(divide by 12 on both sides)
m - 5 = 45
m = 50 ( add 5 on both sides)
Anzelm should plan to be out jogging for 50 minutes
