lisabon 2012 [21]2 years ago
4 0

Answer:

the answer is 7x + 437

Step-by-step explanation:

1) 7 is the only number with a variable, <em>x</em>, so it will remain as it is.

2) -4+4= 0

3)1+1= 2

4) 2+435= 437

7) combine 7x and 437 together. 7x + 437.

We cant go any further, because 7x and 437 are not liketerms.

Clare is painting some doors that are all the same size. She used 2 liters of paint to cover 1 and 3/5 doors. How many liters of
vitfil [10]

Answer:

1 and 1/4 liters of paint are needed for one door

Step-by-step explanation:

You can eliminate each answer choice out. For '4/5 liters' you know that if that amount was used, it wouldn't be reasonable since it would mean that the more was used for the other 3/5 door. 3 and 1.5 would be too much since it is over 2 liters. 2 liters wouldn't be logical since you paint 1 <em>and</em> 3/5 of a door and you only used 2 liters, no more or no less, basically what would you use for the other 3/5 door if this was the answer.

Hope this helps!

Sharon and Sue are making muffins. Sharon uses 3 cups of milk, and Sue uses 1 pint of milk. Who uses the greater amount of milk?
stiks02 [169]

answer:

Sharon used more milk because 3 cups equal 1.5 (one and a half) pints.

Detailed answer:

1 cup equals 0.5 pints or half of a pint. So if you take 0.5 and multiply it by 3 you get 1.5 and that is the amount of pints that Sharon uses but Sue uses 1 pint or 2 cups. so 1.5 pints is grater than 1 pint by 0.5

(sorry if this was not so clear i am not that good at explaining things, also i hope this helps and you get a good score on whatever you are doing.)

If the area of a circle is 58 square feet, find the circumference. A. 42.5 ft. B. 4.25 ft. C. 22.35 ft. D. 26.99 ft.
PSYCHO15rus [73]

Answer: OPTION D.

Step-by-step explanation:

The formula for calculate the circumference of a circle is:

C=2r\pi

Where <em>r</em> is the radius.

The formula for calculate the area of a circle is:

A=r^2\pi

Where <em>r</em> is the radius.

Solve for <em>r</em> from A=r^2\pi to calculate it:

r=\sqrt{\frac{A}{\pi}}\\r=\sqrt{\frac{58ft^2}{\pi}}\\r=4.296ft

Subsitute the radius into C=2r\pi. Then:

C=(2)(4.296ft)\pi=26.99ft

The second of two numbers is 3 less than twice the first. Their sum is 36. Find the numbers.
o-na [289]

Answer:

13 and 23

Step-by-step explanation:

create an equation to solve:

(2x-3) + x = 36

3x - 3 = 36 combine like terms

<u> +3 +3</u><u> </u> add 3 to both sides

<u>3</u>x = <u>39</u>

3 3 divide both sides by 3

x = 13

<u>13 is the first number</u>

the 2nd number is 3 let than twice the first so we create and solve a new equation:

2x - 3 = ?

2(13) = ? substitute 13 from the

smaller number to solve

<u>23 = the 2nd number</u>
