ikadub [295]3 years ago
6 0

Standard form is Ax +By =c

y = -4/5 x -7

multiply by 5

5y = -4x -35

add 4x to each side

4x +5y = -35

multiply by -1

-4x -5y = 35

Edward is driving a car on the highway. He drives for 28.5 miles in 3/8 of an hour. At this rate, how much distance can he cover
Rom4ik [11]

The distance covered in one hour is 76 miles.

<u>Step-by-step explanation:</u>

Edward drives a car for 28.5 miles.

Therefore, the distance he travels by the car = 28.5 miles.

The time it takes to drive 28.5 miles is 3/8 of an hour.

<u>The formula to find the rate :</u>

Rate = Distance traveled / Time taken in hours.

Here, the distance is 28.5 miles and time is 3/8 hour.

Rate = 28.5/ (3/8)

<u>To find the distance covered in 1 hour :</u>

Let us assume, 'x' be the distance covered in one hour.

Rate = x/1

<u>Now, comparing the rates to find the x value :</u>

⇒ 28.5 / (3/8) = x /1

⇒ x = 28.5 \times  8/3

⇒ x = 228/3

⇒ x = 76

Therefore, the distance covered in one hour is 76 miles.

So the correct statement is:

" The GCF of the numbers in each term in the expression is 2"

<h3></h3><h3>How to rewrite the expression as a product?</h3>

Here we have the expression:

12d - 26c

To rewrite ti as a product, we need to find the greatest common factor between 12 and 26.

The decomposition of these two numbers is:

12 = 2*2*3

26 = 2*13

The greatest common factor between the two numbers is 2, then we can rewrite:

12d - 26c = 2*(6d - 13c)

So the correct statement is:

" The GCF of the numbers in each term in the expression is 2"
