Answer:
The rectangle is 10 cm by 18 cm.
Step-by-step explanation:
Let x represent the distance from the center of the rectangle to the longer side. Then the distance to the shorter side is x+4. The short side of the rectangle will have length 2x, and the long side will have length 2(x+4) = 2x+8.
The perimeter is twice the sum of the side lengths, so is ...
56 = 2(2x +(2x+8)) = 8x +16
40 = 8x . . . . . . . subtract 16
40/8 = x = 5 . . . divide by the coefficient of x
The side lengths are 2x=10 and 2x+8 = 18 centimeters.

Answer:
y = -5x + 7
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Define
5x + y = -2
Random point (2, -3)
Step 2: Rewrite
y = -5x - 2
m = -5
Step 3: Write parallel line
y = -5x + b
-3 = -5(2) + b
-3 = -10 + b
7 = b
y = -5x + 7
Answer:
$46
Step-by-step explanation:
A percent is a portion of 100. If we receive 25% off then we pay 75% of the price. 100%-25%=75%. $34.50 is 75% of the original price. We find the new price through a proportion. A proportion is an equation where two ratios or fractions are equal. The ratios or fractions compare like quantities. For example, we will compare percent over percent to an equal ratio of $ to $.
I can now cross-multiply by multiplying numerator and denominator from each ratio.
I now solve for y by dividing by 75.
The original price was $46.
