Answer:

Yes

Step-by-step explanation:

If you add 87.84, 85, and 100 you get 272.84. Once you divide that by 3 you get 90.946, which would be your test average if you score 100 on your next test.

• Write an expression for the perimeter of a
Ksenya-84 [330]

Answer:

10 (X+1)

Step-by-step explanation:

Length = 2x + 5

Width = 3x

Perimeter of rectangle= 2(L + W)

P= 2\times (2x+5+3x)

P= 2\times (5x+ 5)

Now, taking 5 as common

P= 2\times 5 (x + 1)

∴ Perimeter of rectangle= 10\times (x+1)

Can someone help me?

Hi Eli!

--------------------------------------

We Know:

1 1/2 cups of flour.

3/4 cup of white sugar.

1/8 cup of brown sugar.

--------------------------------------

Part A:

I can't use a number line answering this question but you can create one with the steps I tell you.

First find common denominators:

1 1/2 = 3/2 = 12/8

3/4 = 6/8

1/8

Create a number that goes from 0/8 to 12/8, which means put a number with 12, 1/8 plots on it. Then plot 12/8, 6/8, and 1/8 in order in the number line.

Find out the total number of cups used:

12/8 + 6/8 + 1/8 = 19/8

Simplify:

19/8 = 2 3/84

Part A Answer: There are <u>2 3/8 cups</u> used all together.

--------------------------------------

Part B:

Part B Answer: The <u>3 cup bowl</u> would work perfectly.

Why: The reason you would want to choose the 3 cup bowl is because it fits all the ingredients perfectly, the 3 cup bowl is greater than the 2 3/8 cups they used. You can't use 2 cups because it is less than the total cups of ingredients. The 4 bowl you could use but it is too big.

--------------------------------------

Hope This Helps :)

Type A coffee costs Bill 4.30
avanturin [10]
4.30A+5.70B=855.40
A+B=168

A=168-B
substitute

4.30(168-B)+5.70B=855.40
4.30*168-4.30B+5.70B=855.40
1.40B =855-4.30*168
1.40B=132.60
B=132.60/1.40= 94.7 pounds≈95 pouds
