40 percents because 20/100=5 5*8=40

Answer:

Step-by-step explanation:

So in order to get the answer you must put this as an equal fractions  8/20 as a fraction that equals to x/100 to get the percentage. After doing that you divide the known part of the fractions which in this case is the Denominators 100/20 gives you 5. After you get that answer you use it to multiply by 8 to get the percentage which I think is 40%

Three times Mary’s age added to Beth’s age is 34 years. Half of Mary’s age minus Beth’s age is 1 year. How old are Mary and Beth?

Answers

The answer for this is 10 4

The age of Mary and the age of Beth will be 10 years and 4 years, respectively.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Three times Mary’s age added to Beth’s age is 34 years. Half of Mary’s age minus Beth’s age is 1 year.

Let 'x' be the age of Mary and 'y' be the age of Beth. Then the equations are given below.

3x + y = 34        ...1

x/2 - y = 1          ...2

From equations 1 and 2, then we have

3(2y + 2) + y = 34

6y + 6 + y = 34

7y = 34 - 6

7y = 28

y = 4

Then the value of the variable 'x' is given as,

3x + 4 = 34

3x = 30

x = 10

The age of Mary and the age of Beth will be 10 years and 4 years, respectively.

More about the solution of the equation link is given below.

3(x-4)=5(x+2)

Answers

Answer:

x = -11

Step-by-step explanation:

1. Distribute 3 to the parenthesis and distribute 5 to the parenthesis

3x-12 = 5x + 10

2. Combine like terms (subtract 3x on both sides and then subtract 10 on both sides)

2x = -22

3. Divide both sides by 2

x = -11

please give me brainliest if this helped

Answer:

x=−11

Step-by-step explanation:

3(x-4)=5(x+2)

Simplify both sides of the equation:

3(x−4)=5(x+2)

(3)(x)+(3)(−4)=(5)(x)+(5)(2)(Distribute)

3x−12=5x+10

Subtract 5x from both sides

−2x−12=10

add 12 to both sides

−2x=22

Divide by -2 both sides

x=−11

Hope this helps.

Find the sales price for a $900 TV with a 25% discount.
Discount = Regular Price X Rate of Discount Sales Price= Regular Price - Discount.
b. Discount (mark down Expression) = ((Original price – (Original price x discount rate))

Answers

Answer:

$675

Step-by-step explanation:

100%=>$900

25%=>X

25% × $900 ÷ 100% = $225

So $900 - $225 = $675

AWNSER

$ 675 with discount

EXPLANATION

If it is 25% off of the sales price we can infer that you are paying 75% of the sales cost.

To find the price you answer the equation

900•.75= 675

Therefore the total cost with the discount of 675 dollars.
