Answer:
4 and 9
Step-by-step explanation:
x+(x+5)=13
2x+5=13
2x=8
X=4
Step-by-step explanation:
you need to solve this using fractions.
Example :
It takes 3 men 8 hours to build a wall. How long would it take 4 men to build the same wall?
For 3 men: It is 1 wall divided by 8 hours, which is 1/8.
For 1 man: It is 1/8 divided by 3, which is 1/24.
For 4 men: It is 1/24 multiplied by 4, which is 1/6, = 6 hours.
Answer:
x-2 =0
x=2
Step-by-step explanation:
we take -2 to the anther side it becomes 2
When rates<span> are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called </span>unit rates<span>. To determine the rate, we just divide the distance traveled by the time it takes. Therefore, the rate of the plane would be
rate = 256 / 30(1/60) = 512 miles per hour</span>
