Strictly speacking, since 'c' is defined in the statement this shoudl work:

Part 1) According to the exercise, the letter 'c' represents the total cost of the three pounds of oranges. So c is the total cost of the three pounds of oranges.

Part 2) Rami has three pounds of oranges. In order to know how much a pound of oranges cost, he will have to divide by 3 the total cost of the three pounds 'c'

Part 3) The cost per pound is:

cost 1 pound of oranges = c/3

Hey please help, thank you!!

Answer:

D

Step-by-step explanation:

So we have the equation:

A=\frac{1}{2}(12)(3+7)

And we want to find out which of the answer choices is <em>not</em> equivalent.

Thus, let's go through each of the choices.

A)

We have:

\frac{12(3+7)}{2}

This is correct.

Our original equation can be written as:

A=\frac{1}{2}(\frac{12(3+7)}{1})

And if we multiply straight across:

A=\frac{12(3+7)}{2}

We'll get choice A. So choice A is correct.

B)

We have:

6(3+7)

This is also correct.

From our original equation:

A=\frac{1}{2}(12)\cdot(3+7)

If we multiply the first term together:

A=6(3+7)

We'll get choice B. So, choice B is correct.

C)

We have:

0.5(12)(10)

This is correct as well.

If we reduce 1/2 to decimal form and add the operations within the parentheses in the original equation, we will get:

A=\frac{1}{2}(12)(3+7)\\A=0.5(12)(10)

So, C is also correct.

D)

We have:

\frac{12}{2}\times\frac{10}{2}

Note that this is not correct.

This attempted to use the distributive property. However, the distribute property does <em>not work</em> for multiplication. For instance:

3(2+1)\text{ indeed equals } 3(2)+3(1)

However:

3(2\times1)\text{ does not equal} 3(2)\times3(1)

So, choice D is not equivalent.

So choice D is our answer :)

If we evaluate it, we will get 30, in contrast to the 60 of the others.

Help me please I don’t understand
statuscvo [17]

Answer:

C

Step-by-step explanation:

It says he walked 2(3/4) miles in 2 hours, and it wants to know how far he walked in 1 mile, which would be that number divided by 2.

2(3/4) is the same as 2.75

2.75/2=11/8

which is equivalent to 1(3/8) miles

Kendra has a painting canvas that is 22 inches wide by 38 inches high. She painted a red rose, which covered 30% of the canvas.
Wittaler [7]

<u>Given: </u>

  • Breadth of canvas is 22 inches.
  • Length of canvas is 38 inches.

<u>To Find:</u>

  • If kendra covered 30% of the canvas by painting red rose, what will be the area of canvas covered by red rose?

<u>Solution: </u>

To find the area of red rose, first we have to find the area of canvas.

★ Area of Rectangle = Length × Breadth

➝ 22 × 38

➝ 836 in²

So, Area of canvas is 836 inches².

★ Area of red rose:-

➝ 30% of 836 in²

➝ 0.30 of 836

➝ 250.8

Hence, Area covered by the red rose is <u>2</u><u>5</u><u>0</u><u>.</u><u>8</u>

<h2> ____________________</h2><h3><u>Additional</u><u> </u><u>Information:</u><u> </u></h3>

★ Triangle => ½bh

★ Rectangle => Length × Breadth

★ Circle => πr²

★ Square => Side × Side

★ Parallelogram => Base × Height

★ Sphere => 4πr²
