Aconstruction company recently built a thirty-story building on a lakefront in china. architects and engineers designed the building to withstand a magnitude 9.0 earthquake. the most impressive thing about this building, though, is that it took only 360 hours to build.

how many days did it take to construct the building?
10 days
15 days
20 days
25 days

The number of days it took to construct the building is 15 days.

In order to determine the number of days it took to construct the building we would divide the number of hours it took to build the house by the number of hours in  a day. In a day, there are 24 hours. This means that would divide the 360 hours by 24 hours.

The number of hours in a day = 24 hours

The number of days it took to build the building = hours it took to build the building / number of hours in a day

360 hours / 24 hours = 15 hours

15 days

360/24 = 15

Hope this helps

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

the answer is (-4,-4)

hope this ! : d
