Answer:
X= 4
Step-by-step explanation:
3x+6/3=6
multiply each side by 3 to get rid of the fraction bar
3x+6=6*3
3x +6=18
-6 from both sides
3x= 18-6
3x=12
divide by three on both sides to solve for x
x=12/3
x=4
-11-(-7)
-11+7
Your answer is -4
I think it is 3 A but it is hard to know what the question is asking... but my logic is that 3 A is right because A = 1+2 = 3
#15(A)
First Bike
$380 - $190 ($380 * 0.50) = $190
2nd Bike
$380 - $114 ( $380 * 0.30) = $266
$266 - $53.20 ($266 * 0.20) = $212.80
#15 (B)
Eliza should buy the first bike because it is cheaper. $190 < $212.80
#16
$57 + $28.50 ($57 * .50) = $85.50
30% off 25: multiply 25 by .30 to find 30%: 7.5. Now subtract that from the sales price: 25-7.5=17.5
Do the same for store B: .40•30=12. 30-12=18.
So store A is better by $.50 :) hope this helps :)
