-1(x + 2) = 2(3x - 6)

First, simplify 1 × (x + 2) to (x + 2) / Your problem should look like: -x - 2 = 2(3x - 6)
Second, expand. / Your problem should look like: -x - 2 = 6x - 12
Third, add x to both sides. / Your problem should look like: -2 = 6x - 12 + x
Fourth, simplify 6x - 12 + x to get 7x - 12. / Your problem should look like: -2 = 7x - 12
Fifth, add 12 to both sides. / Your problem should look like: -2 + 12 = 7x
Sixth, add -2 + 12 to get 10. / Your problem should look like: 10 = 7x
Seventh, divide both sides by 7. / Your problem should look like: \frac{10}{7}  = x
Eighth, switch your sides. / Your problem should look like: x =  \frac{10}{7}

Answer: x = \frac{10}{7}
Answer as decimal: 1.4286

-1(x+2)=2(3x-6)
-1(x+2)=2(3x-6)distributhing -1 through parantheses
-1x+(-1)*2=2(3x-6)
-x-2=2(3x-6) distributhing 2 through parantheses
-x-2=2*3x-2*6
-x-2=6x-2*6
-x-2=6x-12    add x 
-2=6x-12+x
-2=7x-12        add 12
-2+12=7x
10=7x       divide by 7  
x= \frac{10}{7}

Given that f(x) = 2x + 1 and g(x) = −5x + 2, solve for f(g(x)) when x = 3.
ANTONII [103]
f(x)=2x+1 \\
g(x)=-5x+2 \\ \\
f(g(x))=2(-5x+2)+1=-10x+4+1=-10x+5 \\
f(g(3))=-10 \times 3+5=-30+5=-25 \\
\boxed{f(g(3))=-25}

The answer is C.

Ashley had a summer lemonade stand where she sold small cups of lemonade for $1.25 and large cups for $2.50. if ashley sold a to
Levart [38]
The answer is 98 small and 57 large cups.

s - the number of small cups
l - the number of large cups

<span>Ashley sold a total of 155 cups: s + l = 155
</span><span>Ashley earned</span><span>for $265: 1.25 * s + 2.50 * l = 265

</span>s + l = 155
1.25 * s + 2.50 * l = 265
________
s = 155 - l
1.25 * s + 2.50 * l = 265
________
1.25 * (155 - l) + 2.50 * l = 265
193.75 - 1.25 * l + 2.50 * l = 265
193.75 + 1.25 * l = 265
1.25 * l = 265 - 193.75
1.25 * l = 71.25
l = 71.25 / 1.25
l = 57

______
s = 155 - l
l = 57

s = 155 - 57
s = 98

Step-by-step explanation:

5x - 2 + x = 9 + 3x + 10

6x - 2 = 9 + 3x + 10

6x - 2 = 3x + 19

6x = 3x + 21

3x = 21

x = 7
