When a number is increased by 2.8%, the result is 56. What is the original number to
Sever21 [200]

Answer:

The original number was 54.5.

Step-by-step explanation:

If a number is increased by 2.8%, then it is 102.8% of it's original number.

In mathematics, "of" in virtually all cases means "multiplied by".

Therefore, we do the opposite:

1. Convert to a decimal.

102.8% = 1.028

2. Divide by the decimal.

56 \div 1.028 = 54.47

3. Round it to the nearest tenth.

54.47 rounds to 54.5.

Alexa worked 30 hours last week and earned $450. Her pay has now been increased by 20%. Which equation describes her new rate of
vesna_86 [32]

Answer:

p=18h

or

p=\dfrac{450}{30}\cdot 1.2\cdot h

Step-by-step explanation:

If Alexa worked 30 hours last week and earned $450, then her hourly payment is

\dfrac{\$450}{30}=\$15.

Her payment has now been increased by 20%, so her hourly payment becomes

\$15\cdot 1.2=\$18.

If she worked h hours, then she earned \$18h. If her new payment is p, then

p=18h

or

p=\dfrac{450}{30}\cdot 1.2\cdot h.

Each pair of polygons below is similar. Find the value of x. Some answers may be decimals.
sergiy2304 [10]

Answer:

The answer to your question is below.

Step-by-step explanation:

14.- Use proportions to solve these problems.

             \frac{x + 6}{10} = \frac{x + 9}{14}

                               14(x + 6) = 10(x + 9)

                               14x + 84 = 10x + 90

                               14x - 10x = 90 - 84

                                         4x = 6

                                           x = 6/4

                                          x = 3/2

15.-        \frac{x - 1}{8} = \frac{x + 2}{10}

                            10(x - 1) = 8(x + 2)

                            10x - 10 = 8x + 16

                            10x - 8x = 16 + 10

                                     2x = 26

                                       x = 26 / 2

                                      x = 13

16.-       \frac{x + 1}{9} = \frac{10/3}{5}

                            5(x + 1) = 9(10/3)

                            5x + 5 = 30            

                                  5x = 30 - 5

                                  5x = 25

                                    x = 25 / 5

                                    x = 5

You have ​$55 in your bank account. Each week you deposit $8 from your allowance and $15 from your paycheck. The equation b=55+(
scoundrel [369]
<h3>After 6 weeks from now you will have $190 in your bank account</h3>

<em><u>Solution:</u></em>

Given that,

You have ​$55 in your bank account

Each week you deposit $8 from your allowance and $15 from your paycheck

<em><u>The equation that gives the amount b in your account after w weeks is:</u></em>

b = 55 + (15 + 8)w

<em><u>How many weeks from now will you have $190 in your bank account ?</u></em>

b = 190

w = ?

Therefore,

190 = 55 + (15 + 8) w

190 = 55 + 23w

23w = 190 - 55

23w = 135

Divide both sides by 23

w = 5.869 \approx 6

Thus after 6 weeks from now you will have $190 in your bank account
