Answer:

Let the original price be x

70% of x = 14

70x/100 = 14

70x/14 = 100

5x = 100

x = 100/5

x = 20

Therefore the original price = $20

Hope this helps!

Answer:

20$

Step-by-step explanation:

We know that 14 is 70% of the original price, the full price being 100%

We set up an equation to find 100%

14 = 70% //So we divide by 7 on both sides to get 10%

2 = 10% //Then times by 10 to get 100%

As a general rule we always try to find 1%, 10%, 25%, or 50% of the original price, as these numbers are quite easy to multiply to 100%

David has 85 white eggs and 28 brown eggs. He puts 6 eggs into each tray and fills as many trays as he can. How many eggs are le

Murljashka [212]

Answer:

5 eggs are left over.

Step-by-step explanation:

Computers love this question. They have a built in command called mod which will give the answer in one line.

L = (85 + 28) mod 6: Print L

Humans have a little tougher time with it. We do it like this

Add 85 and 28 = 113

Divide by 6

113 / 6 = 18.8333333

What is left over is 0.833333333. But what does that mean, and how do you get rid of it?

Answer Number of Trays: The 18 is easily explained. He can fill 18 trays.

But we still have 0.83333333 to deal with.

The simplest way is to multiply that by 6.

6 * 0.833333333 = 5

The answer is 5

lord [1]

Answer:

showing bellow

Step-by-step explanation:

Let me use an exsample to show this.

Nash is making a framed enlargement of a Mary Cassatt postage stamp to present to a retired postmaster. He enlarges the stamp using a scale of 2 inches to 1 centimeter. If the actual length of the stamp is 3 centimeters and its width is 5 centimeters, what are the dimensions of the scale picture?

6 inches by 10 inches

Step-by-step explanation:

It tells us that the scale is 2 In: 1 cm so we know that for every centimeter long or wide the stamp is the enlardged scale is two inches.

2 times 3 is 6. 6 inches. we are multiplying two inches by the number of centimeter long it is.

5 times 2 is 10 inches. we are multiplying two inches by the number of centimeter wide it is.

therefore the enlarged stamp is 6 In by 10 In.

Hope this helps :)

Answer: The correct answer is Choice C.

Step-by-step explanation: The drama club raised 150% of their goal, which is represented by choice c.

The proper way to calculate this percentage is to calculate how much they earned over the goal. They earned $150 over a goal of $300, so you divide 150 by 300 to determine the percentage.

150/300 = .5, or 50%

So, they earned 100% (300) plus 50% (150), for a total of 150% of the goal.

Solve the following equation. –4y + 8 = 4(2y – 2) – 2(–16 + 8y) A. y = –4 B. y = 4 C. y = –2 D. y = –6 I need Help I am utterly

leonid [27]

The answer is B. (y = 4)

Further explanation:

–4y + 8 = 4(2y – 2) – 2(–16 + 8y)
= -4y + 8 = 4 * (2y -2) - 2 * (-16 + 8y)
= -4y + 8 = ( 4 * 2y - 4 *2 ) - (2 * -16 - 2 * 8y )
= -4y + 8 = 8y - 8 - ( -32 - 16y)
= -4y + 8 = 8y - 8 + 32 + 16y
Move y’s to the left & numbers to the right
= -4y - 8y - 16y = -8 + 32 - 8
= 12y - 16y = -16 + 32
Y = 16 / 28
Y = 4 = (B choice)
