Answer:

The shorter piece is 52 inches

Step-by-step explanation:

Since we don't know what the shorter length is for now we will just call it x. So x+ the second piece is equal to 156 inches. The second piece is two times larger than the smaller piece (x) which means the larger piece has to be equal to 2x. Using this we can set up an equation x+2x=156 inches. x+2x is equal to 3x, so in order to get x by itself we need to divide both sides by 3 so x is equal to 52.

x+2x=156

3x=156

3x÷3= 156÷3

x=52

Why are 4(5) and 20 equivalent expressions?
Studentka2010 [4]

Answer:

4 times 5 = 20, and 20 is... well.. 20

Step-by-step explanation:

When a number has another number in parentheses by it, it means you multiply the numbers together. So 4(5) is the same as 4 times 5, which equals 20

HELP PLS ILL MARK U BRAINLIEST
umka2103 [35]

Answer:

-3.4p + 3p + 4

Step-by-step explanation:

Solve the parenthesis with the minus sign in front of it. Basically, inverse all of the operations within the parenthesis.

The -3q will become a 3q and the -4 will become a 4.

So now with the positive 3q and 4, you will just add those to the -3.4p

Therefore, the answer is -3.4p + 3p + 4

Hope this helped! Please mark me as brainliest!

You are playing an Algebra 1 board game with your friends in Mr. Harris's class. It is your turn. You roll the dice and move you
guapka [62]
From here, we need to start by making an equation:

We know that it has a common difference of 6, thus, the slope is -6.

22 = -6(6) + b
b = 58

So we have our equation:


y = -6x + 58

Let's plug 50 in and we get -242
