Can someone please help me with this question?

x = 8

Step-by-step explanation:

The area of a triangle can be found using the formula , where

h = the height of the triangle

b = base of the triangle

In this case, the height of the triangle is x, and the base is 4, while the total area is 16 .

We can substitute that into the area equation, and we will get

1) Multiply both sides by 2

You will get x * 4 = 32

2) Divide both sides by 4

You will get x = 8

So, x will have a length of 8 units.

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
