Answer:

20x + 18

Step-by-step explanation:

We need to use the distributive property, where we essentially take the sum of the product of the outside number with each of the inside terms.

In 7(4x - 2), 7 is the outside number and 4x and -2 are the inside numbers, so:

7(4x - 2) = 7 * 4x + 7 * (-2) = 28x - 14

In 4(2x - 8), 4 is the outside number and 2x and -8 are the inside numbers, so:

4(2x - 8) = 4 * 2x + 4 * (-8) = 8x - 32

Now, we have:

28x - 14 - (8x - 32) = 28x - 14 - 8x + 32 = 20x + 18

The answer is 20x + 18.

Step-by-step explanation:

<u>Step 1:  Distribute</u>

<u />7(4x - 2) - 4(2x - 8)

(7 * 4x) + (7 * -2) + (-4 * 2x) + (-4 * -8)

(28x) + (-14) + (-8x) + (32)

28x - 14 - 8x + 32

<u>Step 2:  Combine like terms</u>

28x - 14 - 8x + 32

20x + 18

Answer:  20x + 18

A game of chance is begun. You will pick one number out of 300. If your number is picked you win $30,000. At what point is it no
garik1379 [7]

Answer:

<$100 / greater than $100

Step-by-step explanation:

30,000/300=100

If you spent $100 per spin and won 1 out of 300 games, there would be no net gain.

If you spent anything more than $100, then you would lose more money than you gained if you won 1 out of 300 games.

Help plssssssssssssssssssssss

Answer:

Then the solution is (4, 6).

Step-by-step explanation:

Let's use the substitution method:

First multiply the second equation by 4, obtaining 4y = -2x + 32.

Now substitute (-2x + 32) for 4y in the first equation:

3x + (-2x + 32) = 36, or

3x - 2x + 32 = 36. or

x = 4.

If x = 4, then the second equation yields y = (-1/2)(4) + 8, or

y = -2 + 8, or y = 6

Then the solution is (4, 6).

Check, using the first equation:

Does 3(4) + 4(6) = 36?  Does 12 + 24 = 36?  YES

I need my smart homies to answer this question for me !
ella [17]

Answer:

Part A: chosen method is by factoring

Part B: First rewrite the equation by writing -24 as a difference so you get     x² -9x - 15x + 135 = 0. Then factor out the x and the -15 from the equation so you get x(x-9) - 15(x-9) = 0. Then factor out x-9 from the equation so you have (x-9)(x-15) = 0. Finally, set each expression to 0: x-9=0 and x-15=0 and then solve: x=9 and x=15

Part C: x=9, x=15
