Answer:

37.7

Step-by-step explanation:

Discount = original price * percent off

The percent is 65% of the original price

The percent off is 100-65 = 35%

Discount = 58* 35%

               = 58 * .35

                 =20.3

Sale price = Original price - discount

                   = 58-20.3

                    =37.70

Write the equation 2y − 4x = 5 in the form y = mx + b.
gtnhenbr [62]

Hello from MrBillDoesMath!

Answer:

y = 2x + 2.5

Discussion:

2y -4x = 5                        => add 4x to both sides

2y - 4x + 4x = 4x + 5        => -4x + 4x = 0

2y = 4x + 5                      => divide both sides by 2

y = 2x + (5/2)                   => as 5/2 = 2.5

y = 2x + 2/5

Thank you,

MrB

Please help i need this done asap
ki77a [65]

Answer:

A

Step-by-step explanation:

Using the rules of exponents

a^{m} × a^{n} = a^{(m+n)}  , a^{-m} = \frac{1}{a^{m} }  , a^{0} = 1

(14x³y^{-4} )(4x^{-5}y^{4} )

= 14 × 4 × x³ × x^{-5} × y^{-4} × y^{4}

= 56 × x^{(3-5)} × y^{(-4+4)}

= 56 × x^{-2} × y^{0}

= 56 × \frac{1}{x^2} × 1

= \frac{56}{x^2} → A

SOLVE FOR THE BASE
zheka24 [161]

Answer:

1-    10% of -80 is -8.  

2-    28 is 4% of 700.

3-   25% of a number is equal to 1/4 or 0.25 of it.

4-    13% of a number is equal to 0.13 of it.

5-    15 is 12.5% of 120.

Step-by-step explanation:

1. 10% of ________- 8

2.28 is 4% of _________

3.25% of ________

4.13% of______

5.15 is 12.5% of _____

To determine the missing numbers in the statements, the following calculations must be performed:

1-

10 = -8

100 = X

100 x -8 / 10 = X

-800 / 10 = X

-80 = X

Therefore, 10% of -80 is -8.

two-

4 = 28

100 = X

100 x 28/4 = X

2800/4 = X

700 = X

Therefore, 28 is 4% of 700.

 

3-

25% of a number is equal to 1/4 or 0.25 of it.

4-

13% of a number is equal to 0.13 of it.

5-

12.5 = 15

100 = X

100 x 15 / 12.5 = X

1500 / 12.5 = X

120 = X

Therefore, 15 is 12.5% of 120.
