Answer :

C.

Step-by-step explanation:

Lynne walk 5 miles in 2 hours that means she walks 2.5 miles an hour

Since we divided an hour to 4 quarters we should do the same to 2.5 miles

2.5 ÷ 4 = 0.625

And since it's asking how far Lynne will walk in 3 quarters of an hour we can multply the number we just found by 3

3 × 0.625 = 1 3/4 approximately

A contractor bought 7.6 ft2 of sheet metal. She has used 3.5 ft2 so far and has ​$123 worth of sheet metal remaining. The equati
Sergio039 [100]

Answer:

Sheet metal remaining = 4.1x

cost per square​ foot of sheet metal = $30

Step-by-step explanation:

Total sheet metal bought = 7.6 ft2

Total sheet metal used = 3.5 ft2

Given equation:

7.6x − 3.5x = 123

Where,

x = cost per square​ foot

7.6x − 3.5x

Sheet metal remaining = 4.1x

7.6x − 3.5x = 123

4.1x = 123

x = 123 / 4.1

x = $30

Cost per square​ foot = $30

If p represents the original price, which of the following expressions could be used to calculate the sale price of a shirt that
dezoksy [38]

Answer:

C & D

Step-by-step explanation:

You can do these two ways. You can multiply the cost of the the shirt by 15% (.15 as a decimal.) and then subtract that answer from the original price of the shirt to get the sales price of the shirt.

You can also multiply the price of the shirt by 85% (.85 as a decimal) and that will give you the sales price without having to subtract. 15% + 85% = 100%, so 85% represents the sales price of the shirt.

Anyway, since you multiply, you can eliminate choice A & B.

Since the direction in the question says to select all that apply, I would check both C & D.

C is the equation of the first way I talked about- Price - 15% * price

C       p - 0.15p

D is the equation of the second way I talked about. Price times 85%

D            0.85p
