Remark
The key to this question is to get the original price (36) down to 29.52. In other words, what % will when multiplied by 36 will result in 29.52?
Solution
36 * (x/100) = 29.52 Multiply both sides by 100
36 * x = 29.52 * 100 The 100 on the left disappears.
36 * x = 2952 The decimal disappears. Divide by 36
x = 2952/36
x = 82%
That is not your answer. That just tells you what % of 36 is that would give 29.52
Answer
The % discount is 100 - 82 = 18%. That is the % discount.
Answer:
x = 1.8/
Step-by-step explanation:
-1.5(-4x-4) = -1.5(-4x) + -1.5(-4) = 6x + 6
The negatives cancel each other out.
4x-2(-5x+8.7)+9 = 4x + -2(-5x) + -2(8.7) + 9 = 4x + 10x -17.4 + 9 = 14x -8.4
6x + 6 = 14x -8.4
-14x -14x
-8x + 6 = -8.4
-6 -6
-8x = -14.4
/-8 /-8
x = 1.8/
Answer:
$0.25
Step-by-step explanation:
To find unit rate divide number of shirts by cost of package
$2.00/8 = $0.25
So each individual golf tee costs $0.25
Answer:
1200 > 42x+400
Step-by-step explanation:
We need to determine the equation of the line for the number of lilac bushes versus area
m = (y2-y1)/(x2-x1)
= (484-442)/(2-1)
= 42/1
= 42 square ft per lilac bush
Using point slope form of a line
y-y1 = m(x-x1)
y-442 = 42(x-1)
Distribute
y-442 =42x-42
Add 442 to each side
y-442+442 = 42x-42+442
y = 42x+400
This is the equation of the line
Ryan has less than 1200 square feet so our equation must be less than 1200 square feet
1200 > 42x+400
