The sum of the perimeters of 2 different squares is 68 feet, and the difference between their perimeters is 12 feet. What is the side length of

each square?

Answers

9514 1404 393

Answer:

10 ft7 ft

Step-by-step explanation:

The side lengths are 1/4 of the perimeter, so we can say ...

the sum of side lengths is 68 ft/4 = 17 ft

the difference of side lengths is 12 ft/4 = 3 ft

Using x to represent the side length of the smaller square, we have ...

x + (x +3) = 17 . . . . . . the larger square has side length x+3

2x = 14 . . . . . . . . . subtract 3

x = 7 . . . . . . . . divide by 2

The side lengths of the squares are 7 feet and 10 feet.

Зу + 9x = 12
y=mx+b

Answers

Answer:

y = -3x + 4

Step-by-step explanation:

3y + 9x = 12

subtract 9x

3y = 12 - 9x

divide by 3 on both sides

y = 4 - 3x

y = -3x + 4

Answer:

y=-3x + 4

Step-by-step explanation:

Convert standard form equation into y-intercept form

3y +9x=12

3y= 12-9x

Divide both sides by 3 to isolate the y (you can flip the equation if it is easier)

y= -3x+4

Mile is obsessed with her new book she started. She read 185 pages in 2 days. If she keeps up this pace about how many pages will she have read after 5 days

Answers

Answer:

462.5 pages

Step-by-step explanation:

You find out how many books she reads in 1 day then you can multiply it by 5 to get 5 days.

If she reads 185 in 2 days. Divide 185 by 2 to get 1 day.

185/2 = 92.5 pages

Now multiply 92.5 by 5 to get how many pages she read after 5 days.

92.5 x 5 = 462.5 pages

Put these numbers in order of their distance from 0 on the number line, starting with the smallest distance. -26,-12.7,-9/2,2/100,::7,::11/1/4,::41/2

Answers

Answer:

2/100, -9/2, 7, 11 1/4, 12.7, 41/2, -26.

Step-by-step explanation:

Given,

Points are -26,-12.7,-9/2,2/100,7,11 1/4,41/2

We have to arrange the number according to their distance from 0.

Simplifying Points

= -26, 12.7, -4.5, 0.02, 7, 11.25, 20.5

Now, arranging the number starting from the smallest distance from 0.

0.02, -4.5, 7, 11.25,12.7,20.5,-26

= 2/100, -9/2, 7, 11 1/4, 12.7, 41/2, -26.

18 bottles of water cost $9. How much does it cost for one bottle of water? How much bottles can you buy with $6?

Answers

Answer:

Water cost 2$ you can buy 3 water bottles with 6$

Step-by-step

I did myself

Answer:

one bottle of water is 0.5 dollars. You can buy three bottles of water for $6

Step-by-step explanation:

since 9 divided by 18= 0.5, this is how it goes

18 bottles broken up into sections of one (one bottle in each section)

so you have to break up the dollars into cents to put an equal amount with each bottle. So you get 100 pennies for each dollar. There's only 9 dollars, so you split the pennies (that you broke from the 9 dollars) and put one in each section (each section still has one bottle) so each bottle with get one more penny with every round. The bottles take turns getting pennies. After you do all of them you will get 0.5 dollars for each bottle so that's how much the bottles cost.

The bottles cost 0.5 dollars.

Now we do this with 6 dollars instead of 9. You now know that each bottle cost 0.5 dollars so you have to do this

0.5 x 6 which = 3.

You can buy 3 bottles with $6.

I hope this helps!

Which equation can be used to find the missing angle?

a. X + 90 = 180
b. X + 40 = 90
c. 180 - 40 = x

Answers

Answer:

A, all three angles of a triangle equal 180

Answer:

b. x + 40 = 90

Step-by-step explanation:

This is a right triangle, so we already know one of the angles is 90 degrees. The other angles combine to make the other 90 degrees. So, we have to figure out what the other angle is, as the second one is 40 degrees. To figure that out, use the equation x + 40 = 90. (This is extra, but x is 50, right?)

Answer:

Step-by-step explanation:

120-72=48

48÷12=4

Answer:

Step-by-step explanation:

The total amount was $120.

A portion of the $120 was for parts.

The rest of the $120 was for service. Service cost $12 per hour.

Start with $120.

Subtract $72 to find the amount spent on service.

$120 - $72 = $48

$48 was spent on service.

The service costs $12 per hour.

$48/($12/hour) = 4 hours

Answer: 4 hours

Check:

$72 in parts + 4 hours * $12/hour = $72 + $48 = $120

4 hours is correct.

(read the passage)THE FIRST FLAG: Betsy Ross made her living as a seamstress, and had many customers. She sewed many things, including clothes, blankets, and curtains. Each day, she would start with a pile of cloth and create things people paid her to make for them. Everyone knew she would do a wonderful job, so they came to her home and asked her to make many items for them. Business was so good, and as she began to get very busy, Betsy hired me to help. I am an experienced seamstress, so I can sew very well.On my first day, three men came to her home and asked if she could make a flag. I listened to them talk with great interest. One of them was named George Washington.1 I had heard of him, and now here he was right in front of me. He came to the store in May. I remember it very well because it was my birthday that day. Washington was leading the army, but the army did not currently have a flag. The army was fighting for freedom,2 but at the time no one knew if we would win.The men showed Betsy Ross a drawing of the flag of the new country. It had stars and stripes. I said, Silver stars would be great. Betsy said, No, it will be too difficult to make those. The flag should be red, white, and blue. So we set to work that day.We worked on the flag for a solid month. It would be very big. In addition to sewing the flag, we had to do other work, too. Betsy said we had to make more clothes to get money. We were making the flag as a present, which meant we would not be paid for the flag.Finally the flag was complete, so George Washington sent someone to come get it. He opened it up and said, This is it. This is just what we need to inspire the army. He did not show it to anyone yet, though. He kept it for a special day.On July 4th, the army flew the new flag. That was the first Independence Day. On that day, the United States said it was a new country. It had a new flag. We were not there, but we heard about it later.The army had to fight more battles. Just saying they were independent did not make it true. The war went on for 7 more years. We worried. We made more flags. In all those battles, soldiers saw that flag. Still, it was difficult to win.When the war ended, the country started. I was proud when I saw the flag. I didnt just make a flag. I was part of making the United States.which statement best identifies the theme of the text?A.when teams work well together, they will overcome many challengesB.Everyday people can contribute to great causes through hard work.C.The best way to bring about great change is through small, kind acts.D.Women had to find creative ways to contribute to history Drag each label to the correct location on the table.Match each battle to the US military leader who won it.Battle of theThamesBattle ofHorseshoeBendBattle of NewOrleansBattle ofPut-in-BayBattle ofTippecanoeWilliam Henry HarrisonOliver PerryAndrew Jackson Simplify the expression: -2x + 3 - (5-6x) what is a technique that synchronizes two different audio and video signals, enabling you to mix images and graphics?WILL GIVE BRAINLY! 999 pencils cost \$7.74$7.74dollar sign, 7, point, 74.Which equation would help determine the cost of 666 pencils?Choose 1 answer:Choose 1 answer:(Choice A)A\dfrac{6}{x} = \dfrac{9}{\$7.74} x6 = $7.749 start fraction, 6, divided by, x, end fraction, equals, start fraction, 9, divided by, dollar sign, 7, point, 74, end fraction(Choice B)B\dfrac{x}{6} = \dfrac{9}{\$7.74} 6x = $7.749 start fraction, x, divided by, 6, end fraction, equals, start fraction, 9, divided by, dollar sign, 7, point, 74, end fraction(Choice C)C\dfrac{9}{6} = \dfrac{x}{\$7.74} 69 = $7.74x start fraction, 9, divided by, 6, end fraction, equals, start fraction, x, divided by, dollar sign, 7, point, 74, end fraction(Choice D)D\dfrac{6}{x} = \dfrac{\$7.74}{9} x6 = 9$7.74 start fraction, 6, divided by, x, end fraction, equals, start fraction, dollar sign, 7, point, 74, divided by, 9, end fraction(Choice E)ENone of the above Which of these job descriptions are interesting to you?
