Lisa's weekly pay increases from $525 to $546
Calculate her percentage pay increase.

Answers

546 - 525 = 21

21 is 4% of 525.


Lisa gained a 4% pay increase.

The percentage pay increase of Lisa's weekly will be 4%.

What is the percentage?

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Lisa's weekly pay increased from $525 to $546. Then the percentage pay increase will be given as,

P = [(546 - 525) / 525] x 100

Simplify the expression, then we have

P = [(546 - 525) / 525] x 100

P = (21 / 525) x 100

P = 0.04 x 100

P = 4%

The percentage pay increase of Lisa's weekly will be 4%.

X=12 would be the answer
Your answer will be x=21 because you have to subtract the 9 over which will give you 42, then you divide by 2 because that is the coefficient in front of the x and your answer will end up being 21.

No. Both recipes call for more than 1 cup, so the recipes will use more than 2 cups altogether. No. Both recipes call for more than half a cup, so the recipes will use more than 1 cup altogether. Yes. Both recipes call for exactly 1 cup, so the recipes will use exactly 1 cup altogether. Yes. Both recipes call for less than half a cup, so the recipes will use less than 1 cup together

Answers

Answer:

Step-by-step explanation:

No, Lynn do not have enough water to make her snack.

What is the fraction?

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Given that, the recipes call for 3/8 cup of water for oats and 1/4 cup of water for dried fruit.

You need to add up the quantities of water needed first. That will then tell if she has enough water.

Convert the fractions to decimals then add them up:

3/8 = 0.375

1/4 = 0.25

= 0.25 + 0.375

= 0.625 cups of water is required.

This is less than the 1 cup she has so she has enough water to make the snack.

No, Lynn do not have enough water to make her snack.

Answers

Answer:

19 feet

Step-by-step explanation:

first, identify which is length and which is width. length is always longer than the width.

in order to do so, we need the measures in the same units, so let's convert . 12 yards to feet and 204 inches to feet:

there are 3 feed in a yard, so let's multiply 12 by 3:

12 • 3 = 36 feet

there are 12 inches in 1 foot, so let's divide 204 by 12

204 ÷ 12 = 17 feet

which is longer? 36 feet! so that's the length

finally, subtract the width(17 ft) from the length (36 ft)

36 - 17 = 19ft

Answer:

Step-by-step explanation:

plus . minus and divide

Answer:

1- Let x = original price  then

x - .20x = 48

x(1 - .20) = 48

x(.80) = 48

x = 48/.80

x = $60

2-Let "x" be the number of lessons.

240 - 15x = 0

240 = 15x  

x = 16 lessons

3-divide equation by 2:

(2W-4) + W = 32

2W - 4 + W = 32

2W + W = 32 + 4

3W = 36

W = 36/3

W = 12 cm

Find the Length using L = 2W-4:

L = 2(12) - 4

L = 20 cm

Check: 2(20) + 2(12) = 64

A toll road company has two plans for customers. One plan charges $10 per month for rental of a transponder (a box that identifies your car on the toll roads) plus $0.60 per mile driven. The second plan does not require that you rent a transponder. Instead, it charges customers $0.75 per mile driven on the toll road. Find the minimum number of miles you would need to drive in a month to make the first deal a better deal.

Answers

Answer:

The minimum number of miles you would need to drive in a month to make the first deal a better deal is 66.6 miles.

Step-by-step explanation:

For the first deal to be a better deal it has to cost less than the second plan and you can write an equation in which the first plan has a lower cost than the second one:

10+0.60m<0.75m, where:

m is the number of miles driven

Now, you can solve for m:

10<0.75m-0.60m

10<0.15m

10/0.15<m

m>66.6

According to this, the answer is that the minimum number of miles you would need to drive in a month to make the first deal a better deal is 66.6 miles.

multiply the numbers:8*5=40

8*5p-8*4

40p-8*4

40p-32

32p+40=40p-32

Subtract 40p from both sides:

32+40-40=40p-32-40

-8p=-72

divide both sides by: -8

-8p/-8=-27/-8

p=9
