The length of a rectangle is two less than four times the width. If the perimeter is 26 cm, find the dimensions of the rectangle

gulaghasi [49]

Answer:

w = 3

l = 10

Step-by-step explanation:

l = 4w-2

P = 26cm

P = (l + w) × 2

26 = (4w-2+w) ×2

26 = (4w + w - 2) × 2

26 = ( 5w - 2 ) × 2

26 ÷ 2 = 5w -2

13 = 5w - 2

13 + 2 = 5w

15 = 5w

w = 3

l = 4w - 2

l = (4 × 3) -2

l = 12 - 2

l = 10

A telescope costs $126 with a 30% discount. What was the original price?

Juli2301 [7.4K]

Answer:

$180

Step-by-step explanation:

Since the cost of the telescope with the 30% discount is $126 then $126 is 70% of the original price. Remember 100-30=70. To find the original price set up a proportion with these values:

$\frac{126}{x}=\frac{70}{100}$

Solve for the original price by cross multiplying numerator with denominator.

x(70) = 126(100)

70x = 12600

x= $180
