Answers

Answer 1

Answer:

The answer is 50r-18

Step-by-step explanation:

2(5r-5) +8(5r-1)=2 x 5r/2 x -5 + 8x 5r/8 x -1

=10r-10+40r-8

=10r+40r-10-8

=50r-18

Madison’s manicure cost $25.90. She wants to leave a 15% tip. Which of the following is closest to the amount of the tip she wants to leave?

A. $2.00

B. $3.00

C. $4.00

D. $5.00

Answers

Answer:

C) $4.00

Step-by-step explanation:

Here's how I did it:

So we're trying to find 15% of $25.90... we can say that the $25.90 is 100% of Madison's Manicure... 100% can also be written as 1.0... why? well if 1.0 is 100%, then we can say any other percentage is proportionate to this... for example... 0.25 is 25% of 1.0... In this case... we are trying to add an additional 15% to the 100% price of the manicure... (Remember... with our proportion we can say that 115% is the same as 1.15) If we take our proportion:

1.15 x 25.90 = 3.89

4.00 is the closest to 3.89

therefore the answer is C) $4.00

The square root of -72

Answers

'8.48528137 i' or 'unidentified'

-72 isn't actually possible because a positive number times a positive number is always a positive and a negative number times a negative number is always a positive number. So you could say "unidentified".

But in HiGh sChOoL you'll learn about imaginary numbers (according to my teachers), and how it works is; basically just find the square root of 72 and write 'i' after. 'I' stands for imaginary number.

3x-x=17-15

2x=2

x=1

Answer:

x=8

Step-by-step explanation:

3x-15=17-x  move variable to the left and change its sign

3x+x-15=17  collect like terms

4x=17 + 15 (3x=x=4x)

4x= 32  divide both sides by 4

x=8   (dividing 4x by 4 cancels the 4,s out and leaves x)

The perimeter of a rectangular ink pad is 22 centimeters the area is 28 square centimeters

Answers

Answer

W=7

Explanation:

The formula for the perimeter for a rectangle is P = 2L + 2W

The formula for the area of a rectangle is A = LW

where L = length and W = width

P = 22 and A = 28

22 = 2L + 2W

28 = LW

Rewriting the 2nd equation L = 28/W

Substituting this into the first equation

22=2(28/W) + 2W

Reworking the equation to eliminate the denominator

22W = 2(28) + 2W2

22W = 56 + 2W2

and

2W2 - 22W + 56 = 0

Dividing by 2

W2 - 11W + 28 = 0

(W-7)(W-4)

Set each factor equal to 0 and solve each for 0

W = 4, W = 7

then W = 4
