Answer:

x = 9

Step-by-step explanation:

First, we want to isolate variable x on the left side of the equation. We can do this by adding 13 to both sides.

x - 13 + 13 = - 4 + 13

x = 9

Explain how to subtract 247 from 538?
alexandr402 [8]
1. 538 - 247 = ?

2. 8 - 7 = 1

3. You can't subtract 3 and 4, so you have to take  number from 5 (turning it into a 4) and then you add a 1 right next to 3 (which makes it 13;13 - 4 = 9

4. 4 - 2 = 2

538 - 247 = 291

So the answer is 291.

Mrs. Avery's class ate 1/5 of their green pepper pizza and 9/12 of their pepperoni pizza. Which pizza did they eat more of?
Anton [14]
So what you have to do is make the denominators equal. You do that by finding out what number they can both go into which is 60. 12 can go into 60 5 times and so you have to do 9/12 times 5 which is 40/60. then 5 goes into 60 12 times so you have to do 1/5 times 5 which is 12/60. Then you see that 40/60 >12/60 therefore the class ate more of the pepperoni pizza

Suppose that water is pouring into a swimming pool in the shape of a right circular cylinder at a constant rate of 7 cubic feet
olchik [2.2K]
V = (pi)r² h
v = (pi)5² h
v = 25(pi) h
take derivative with respect to h
dv/dh = 25(pi)

(dv/dt)*(dt/dh) = dv/dh

dv/dt is given to be 5 cm³
solved for dv/dh = 25(pi)

5(dt/dh) = 25(pi)
dt/dh = 25(pi)/5
dt/dh = 5(pi)

then the recipricol of dt/dh; we want to find dh/dt = 1/(5(pi))
