5. -10y+18=-3(5y-7)+5y
do the parenthasees first
-10y+18=-15y+21+5y
group like terms (y with y and numbers with numbers)

-10y+18=-10y+21
add 10y to both sides and you get
18=21 which is false
so no solution

6. 8(t+2)-3(t-4)=6(t-7)+8
do the parenthasees
8t+16-3t+12=6t-42+8
group like terms
5t+28=6t-36
subtract 5t from both sides
28=t-36
add 36 to both sides
64=t

7. do the parenthasees first
20+8x-5=9x+21
add like terms
15+8x=9x+21
subtract 8x from both sids
15=x+21
subtract 21 from both sides
x=-6

8. distribute the parenthasees
12x-48+3=15
add like terms
12x-45=15
add 45 to both sides
12x=60
divide both sides by 12
x=5

Elliot and kay both bought the same lunch box for $6. Elliot lives in Oklahoma and pays 4.5% in sales tax, while Katy lives in South Carolina and pays 6% in sales tax. how much more did Katy pay in sales tax than Elliot a.$0.09
b.$0.27
c.$0.63
d.$0.36

Answers

Multiply the price by the amount of sales tax and then subtract the two:

Elliot:
4.5% = 0.045
6 * 0.045 = 0.27 sales tax

Katy:
6% = 0.06
6*0.06 = 0.36 sales tax

Difference = 0.36 - 0.27 = 0.09

The answer is A.
