Question 10
A pair of sneakers is originally priced at
$125. They are on sale for $75. What is
the percent discount?


-please show your work

Answers

Answer: 40% discount

Step-by-step explanation:

First lets find the difference between original price and sale price so $125-$75= $50

So we get a discount of 50 dollars off the original price

Next lets find out how much of %$125 is that $50 so [tex]\frac{50}{125}[/tex] as a decimal is .4 or 40%. To check our work lets multiply 125 by 0.4 so 125*0.4= 50 which is the discount.

a can do.a piece of work in 6 days and B in 8 days each working 7hours a day In what time will they finish it together, working 8hrs a day

Answers

A can complete the work in 7*6 hrs = 42 hrs. A can complete in 1 hr = 1/42 part. B can complete the work in 7*8 hr = 56 hrs. A&B together do in 1 hr = 1/42 + 1/56 = 7/168 = 1/24 part. So they will do in 8 hrs = 8*1/24 = 1/3 part. Hence they need 1÷1/3 = 3 days to complete the work.

15h - 4 = 6
Two step problem

Answers

Answer:

h = 10/15

Step-by-step explanation:

Isolate the variable, h. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, add 4 to both sides of the equation:

15h - 4 (+4) = 6 (+4)

15h = 6 + 4

15h = 10

Next, divide 15 from both sides of the equation:

(15h)/15 = (10)/15

h = 10/15 or 0.667 (rounded)

2 (3x - 5) + 4 = -18


Solve for 20 Points

Answers

Answer:

x = -2

Step-by-step explanation:

2(3x - 5) + 4 = -18

Distribute the 2

6x - 10 + 4 = -18

6x - 6 = -18

Add 6 to both sides

6x = -12

Divide both sides by 6

x = -2

Check:

2(3x - 5) + 4 = -18

substitute x = -2 into the original equation

2(3(-2) - 5) + 4 = -18

2(-6 - 5) + 4 = -18

2(-11) + 4 = -18

-22 + 4 = -18

-18 = -18

So x = -2 is true.

Answer:

x=-2

Step-by-step explanation:

2(3x-5)+4=-18

We move all terms to the left:

2(3x-5)+4-(-18)=0

We add all the numbers together, and all the variables

2(3x-5)+22=0

We multiply parentheses

6x-10+22=0

We add all the numbers together, and all the variables

6x+12=0

We move all terms containing x to the left, all other terms to the right

6x=-12

x=-12/6

x=-2
