For #1. Step 1: Set the equations equal to one another: (3x + 20) = (2x + 40)

Step 2: Subtract 2x on both sides of the equal sign: (3x-2x + 20) = (2x-2x + 40)

x + 20=40

Step 3: Subtract 20 on both sides of the equal sign: x + 20-20= 40-20

x=20

Step 4: plug in 20 for x: 3(20) + 20= 80 & 2(20) + 40= 80

Pls help! if given f(x) =-4x-2 and g(x) =2x, what is (f•g) (x)?
Tpy6a [65]
Set up the equation:

(-4x - 2) \times 2x

Distribute 2x to both of the terms in parentheses:

-4x \times 2x = -8x^{2}
-2 \times 2x = -4x

-8x^{2} - 4x

The answer is B.

Luna ray has 1 orange pick for every 2 green picks.How many green picks does Luna have if she has 12 total picks?
Lana71 [14]

Answer:

8 green picks

Step-by-step explanation:

Since this problem is a ratio that also gives a total, setting up equivalent ratios in a table with the total would be a good way to find the answer.  Since there is 1 orange pick for every 2 green picks and there are a total of 12 picks, we can set up the following:

Orange 1 2 3 4 5

Green 2 4 6 8 10

Total 3 6 9 12 15

You can see from the table, that when there are 12 total picks, 4 of them are orange and 8 of them are green.
