Answer:

A. 84x - 16y - 10.6

Explanation:

\sf \rightarrow 2(14x-3y+28x+12.2-5y-17.5)

\sf \rightarrow 2 (42x-8y-5.3)

apply distributive method: a(b + c) = ab + ac

\sf \rightarrow 2 (42x) -2(8y)-2(5.3)

\sf \rightarrow 84x -16y-10.6

NEED ANSWER ASAP PLEASE WILL GIVE BRAINLIEST An integer n is divided by 2 and the quotient is an even integer. What does this te
Nesterboy [21]

Answer:

n is a multiple of 4

Step-by-step explanation:

Let's think about this.

Even numbers are basically numbers that, when divided by 2, get us an integer.

This means that n must be an even integer.

<em>However,</em>

Every other even number, when divided by 2, gets you an odd integer.

This means that every second even number, n \div 2 gets us an even number.

This also means that every time n \div 2 is an even number, n will be a multiple of 4 (as 2\cdot 2 = 4).

Test this out with any even number that's a multiple of 4 (all multiples of 4 are even numbers)

Hope this helped!

Solve for x. 4x − 33=7
tatuchka [14]

Note the equal sign. What you do to one side, you do to the other.

Do the opposite of PEMDAS. First, add 33 to both sides

4x - 33 (+33) = 7 (+33)

4x = 40

Next, divide by 4

4x/4 = 40/4

x = 40/4

x = 10

10 is your answer

hope this helps
