Solve the equation 1.5y < -6.75

1 answer:

7 0

1.5y < -6.75

First, divide both sides by '1.5'.
$\frac{-6.5}{1.5}$
Second, since 4.5 × 1.5 = 6.5, simplify the fraction to '-4.5'
$y \ \textless \ -4.5$

Answer: y < -4.5

John cut a paper square with a perimeter of 18 inches into two rectangles. The perimeter of one of the rectangles is 10 inches.

Lady_Fox [76]

Answer:

13.5 inches

Step-by-step explanation:

Perimeter of the paper square = 18inches

Perimeter of a square = 4s

4s = 18 inches

s = 18/4 = 4.5 inches

Therefore, each side of the square = 4.5 inches.

When the square is cut into 2 rectangles,

The perimeter of one of the rectangles is 10 inches.

Perimeter of the second rectangle = 2L + 2W

Let the length of the rectangle (L) = one side of the square = 4.5 inches

Width of the Rectangle = Length of the square/2 = 4.5 inches/ 2 = 2.25

Perimeter of the second rectangle = 2(4.5) + 2(2.25)

= 9 + 4.5

= 13.5 inches

Pedro bought a skateboard last week. The list price of the skateboard was $64.90. He has a 20% coupon. He has to pay 8.5%

Lapatulllka [165]

Take the original price and times it by .8 (you could times it by .2 and then subtract from the original price but multiplying it by .8 is much easier) 64.9x.8= 51.92 take your discounted price and multiply it by 1.085 to account for the sales tax (you multiply by 1.085 to account for the price of the item and the tax you could times it by .085 and then add it on to the price of the item but this way it shortens the amount of steps needed) 51.92x1.085= 56.3332
Round to the nearest cent
Answer=$56.33
