Two construction elevators are starting at different heights on a building. The first is 130 feet high and is rising at a rate of 7 feet per minute. The second is 226 feet high and is descending at a rate of 5 feet per minute. How long will it take for them to be at the same height?

It will take 8 minutes to be on same height.

Step-by-step explanation:

Let x= Time taken to be at same height.

The first is 130 feet high and is rising at a rate of 7 feet per minute.

Height = 130+7x

The second is 226 feet high and is descending at a rate of 5 feet per minute.

Height = 226-5x

According o the question,

Hence, it will take 8 minutes to be on same height.

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:

60: 45 =12: 9 =4: 3 so the answer is 4: 3
