The sum of two numbers is 58. The first number is 8 less than half the second number. Let c represent the first number. Let d re

Answer: A ,C,G and H are correct statements. Look into the step by step for more understanding.

Step-by-step explanation:

To solve for this problem let's find the actually numbers.

so we know that c + d=58 and also c= 1/2d-8

We have two systems of equations

c+d = 58

c= 1/2d - 8

Solve for c by substitution. Substitute the second equation into the first one.

1/2d -8 + d = 58 Add 8 to both sides

1/2 +d = 66

3/2d =66 Divide both sides by 3/2

d=44 Now we know the d which is the second number is 44 so subtract it from 58 to find the first number.

58 - 44 = 14

we will represent the statements by letters from A going.

A. The equation c + d = 58 represents the sum of the two numbers

B. The equation c+d=58 represents the sentence "The first number is 8 less than half the second number."

C.The equation c= 1/2d -8 represents the relationship between the two numbers.

D. The equation c= 1/2d - 8 represents the sum of the two numbers.

E. The number d is 14.

F. The number c is 44.

G. The number c is 14.

H. The number d is 44.

Now looking at the statements, A ,C,G and H are all correct.

myrzilka [38]

Answer:

the number of hamburgers sold on Thursday were 325.

Step-by-step explanation:

The total number of hamburger and cheese burger is missing

i will replace it with any figure, you can replace it wit your given data and you will get the solution.

A local hamburger shop sold a combined total of 593 hamburgers and cheeseburgers on Thursday

There were 57 fewer cheeseburgers sold than hamburgers

How many hamburgers were sold on thursday

Let h be the number of hamburgers and c be the number of cheeseburgers.

Using this information we can set up two equation as:

$h+c=593\\c=h-57$

Now we need to solve these two equations to get the value of number of hamburgers. For that we use substitution method as shown below:

$h+h-57=593\\2h-57=593\\2h=650\\h=325$

Therefore, the number of hamburgers sold on Thursday were 325.

The length of a rectangle is four times its width.

laila [671]

Answer:

Length: 40 inches

Width: 10 inches

Step-by-step explanation:

Let $x =$ width of the rectangle.

From the information "length of a rectangle is four times its width", we can express the length as:

Length = $4x$

- - - -

Perimeter = $2l+2w$ (formula for perimeter of rectangle)

$100=2(4x)+2(x)$

$100=8x+2x$

$10x=100$ (combine like terms)

$x=10$ inches

∴ The width of the rectangle is 10 inches.

To find the length of the rectangle, we can use substitution:

Length = $4x$

$=4(10)$

$=40$ inches

∴ The length of the rectangle is 40 inches.

Hope this helps :)
