Gordon types 43 3/4 pages in 3 1/2 hours. What is his rate in pages per hour
Olegator [25]

Answer:

His rate is 12 1/2 pages per hour.

Step-by-step explanation:

Given that,

Gordon types 43 3/4 pages in 3 1/2 hours or Gordon types 175/4 pages in 7/2 hours./ We need to find its rate in pages per hour. So,

R=\dfrac{\dfrac{175}{4}\ \text{pages}}{\dfrac{7}{2}\ \text{hour}}\\\\R=\dfrac{175}{4}\times \dfrac{2}{7}\\\\R=12.5\ \text{pages per hour}\\\\R=12\dfrac{1}{2}\ \text{pages per hour}

Hence, his rate is 12 1/2 pages per hour.

the perimeter of a rectangle is 54 feet, and the length is 13 feet more than the width. Find the width of the rectangle, in feet
zubka84 [21]

Answer:

The width of the rectangle is <u>7 feet</u>.

Step-by-step explanation:

Given:

The perimeter of a rectangle is 54 feet, and the length is 13 feet more than the width.

Now, to find the width of the rectangle.

Let the width be x.

So, the length is 13+x.

Perimeter = 54 feet.

Now, to get the width we put formula:

Perimeter=2(length+width)

54=2(13+x+(x))\\54=2(13+x+x)

54=2(13+2x)

54=26+4x

<em>Subtracting both sides by 26 we get:</em>

28=4x

<em>Dividing both sides by 4 we get:</em>

7=x\\x=7\ feet.

Therefore, the width of the rectangle is 7 feet.

What is solution of 8x-2y =1 and -4x+y = 3
Maksim231197 [3]

Answer: it has no solution

Step-by-step explanation:

8x - 2y = 1 ..................... equation 1

-4x + y = 3 ...................... equation 2

solving the system of linear equation by substitution method . From equation 2 , make y the subject of the formula.

y = 3 + 4x .......................... equation 3

substitute equation 3 into equation 1 .

8x - 2(3 + 4x ) = 1

8x - 6 - 8x = 1

8x- 8x - 6 = 1

-6 = 1

this means that the equation has no solution
