If 1/4 of a number is 5 less than 2/3 of the same number, what is the number?

Answers

Answer:

12

Step-by-step explanation:

x/4 = (2x/3) - 5. Solve for x

20 points each!!! Heather has 2 less than 5 times the amount of shoes that Donna has, Gina has 1 more than 2 times
amount of shoes that Donna has. Let x represents how many shoe Donna has.

a. Write an expression that represents how many more pairs of shoes Heather has than Gina.

b. Simplify the expression:

c. How many more pairs of shoes does Heather have is Donna has 14 pairs of shoes?

Answers

Answer:

A. (5x - 2) - (2x +1)

B.  x -1

C. 68

Step-by-step explanation:

Heather = 5 times Donna -2   H = 5D - 2

Gina = 2 times  Donna + 1    G = 2D + 1

Plug in D for X and you get

H = 5x -2

G = 2x + 1

If Heather's expression is 5x -2 and Gina's expression is 2x + 1 then to show how many more Heather has than Gina. You have to subtract Gina from Heather.

(5x - 2) - (2x +1)

Now to simplify it, you just combine all the like terms.

5x - 2 - 2x -1 = 3x - 3   and then you can simply this further by dividing all terms by 3.    x - 1

To solve how many Heather has if Donna has 14. You substitute 14 for x in Heather's equation.    5 (14) -2  =  70 - 2 = 68
