Y = 2x + 4 <br> 16x + 4y = 40

Dafna11 [192]

<span>Y = 2x + 4
16x + 4y = 40

substitute </span>Y = 2x + 4 into <span>16x + 4y = 40

</span><span>16x + 4y = 40
</span>16x + 4(2x + 4) = 40
16x + 8x + 16 = 40
24x = 40 - 16
24x = 24
x = 1

Y = 2x + 4
Y = 2(1) + 4
Y = 6

The value in cents of 4 quarters and x dimes is

Zina [86]

To add numbers, their units should be the same. We need first to convert the quarters and dimes into cents.
4 quarters is equal to 100 cents, while a dime is equal to 10 cents.
In formula, the answer would be 100+10x. ( x refers to the number of dimes)

Which expressions are equivalent to Negative 9 (two-thirds x + 1)? Check all that apply.

Sav [38]

<u><em>Answer:</em></u>

<u><em /></u> $-9(\frac{2}{3}x) + 9(1)\\ \\-6x + 9$

<u><em>Explanation:</em></u>

<u>Before we begin, remember the following rules:</u>

<u>1- Distribution property:</u>

<u /> $a(b+c) = ab+ac$

<u>2- Simplification of fractions:</u>

<u /> $\frac{xy}{yz}=\frac{x}{z}$

<u>3- Signs in multiplication:</u>

+ve * +ve = +ve

-ve * -ve = +ve

+ve * -ve = -ve

<u>Now, for the given problem, we have:</u>

<u></u> $9 (\frac{2}{3}x + 1)$

<u>Starting with the distributive property:</u>

<u /> $-9 (\frac{2}{3}x +1) = -9(\frac{2}{3}x) - (-9)(1) = -9(\frac{2}{3}x) + 9(1)$

..................>This corresponds to option 1

<u>Now, we simplify the output from the above step:</u>

<u /> $-9(\frac{2}{3}x) + 9 = \frac{-9*2}{3}x + 9 = -6x+9$

................> This corresponds to option 5

Hope this helps :)
