Answer:

10

Step-by-step explanation:

Plug in 5 for x, and 10 for y in the expression:

5 + 7(5) - 3(10)

Remember to follow PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponent (& Roots)

Multiplication

Division

Addition

Subtraction

First, Multiply:

7 * 5 = 35

-3 * 10 = -30

5 + 35 -  30

Combine like terms:

(5 + 35) - 30

40 - 30 = 10

10 is your answer.

NemiM [27]

Answer:

B. 314 cm³

Step-by-step explanation:

We are given that,

Height of the cone = 12 cm

Radius of the cone = 5 cm

<em>Since, we need to fill the cone with the cement. So, we will find the volume of the cone.</em>

So, Volume of the cone = \frac{1}{3}\pi r^{2}h

i.e. Volume of the cone = \frac{1}{3}\pi 5^{2}\times 12

i.e. Volume of the cone = \frac{1}{3}\times 3.14 \times 25\times 12

i.e. Volume of the cone = \frac{942}{3}

i.e. Volume of the cone = 314 cm³

Hence, the amount of cement they can put in each cone is 314 cm³.

NikAS [45]
I believe that this is correct. the 39 and 24 stand for how much they pay per copy but you have to add the 48 for Debbie because she had bought the copier so you needed to add that extra amount.
