$56.70 take away the tax first which brings you to $54 then 54x.10% is 5.40 so take 5.40 away from $54 you then have $48.60 then you can add the tax back in +2.70 = $51.30
-7
Step-by-step explanation:
First, set the equation equal to one and the x's to 2
Then, solve the parts without variables
4(2)+a(2)+6(2)-5=1
8+a(2)+6(2)-5=1
8+a(2)+12-5=1
Then add like terms
8+a(2)+7=1
15+a(2)=1
Then subtract 15 from both sides
a(2)=-14
Finally, divide by two on both sides
a=-7
Positive? So are these fractions negative? But here's my answer, 3/8 + 1/4 = 5/8.
(5 Neighbors) x (($1.00 Box) + (? Plant) + ($3.00 Gloves)) = 42.50
5 x (1 + x + 3) = 42.50
Combine in parens.
5 x (4 + x) = 42.50
Distribute.
20 + 5x = 42.50
Subtract 20 from both sides.
5x = 22.50
Divide both sides by 5.
x = 4.50
Thats the cost of each plant.
Check.
5 x (1 + 4.50 + 3)
5 x 8.50 = 42.50
6) D , 7) A, 8) 8) C
