Answer:
x-1= 4x +x -8 +3x (combine like terms on the right side)
x-1= 8x -8 (subtract 8x from both sides, and the same time add 1 to both sides
-7x= -7 (divide by -7 on both sides)
x=1

Answer:
let's say the price is 400 dollars
and the percent of markdown is 20%
100-20=80
400x80=32000
32000/100= 320
The price will be 320 dollars.

Answer:
x = 17
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
-243 = -9(10 + x)
Step 2: Solve for x
Divide -9 on both sides: 27 = 10 + xIsolate x: 17 = xRewrite: x = 17Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -243 = -9(10 + 17)Add: -243 = -9(27)Multiply: -243 = -243Here we see that -243 does indeed equal -243.
∴ x = 17 is the solution to the equation.

At its maximum speed, a motorboat can travel 10 miles downstream on a river in 20 minutes. It takes 30 minutes for the boat to travel back upstream the same 10 miles, also at maximum speed.
Write a system of two equations that could be used to find the maximum speed of the motorboat in still water. Let b represent the maximum speed of the motorboat in miles per hour and let r represent the speed of the river's current in miles per hour. Convert the times into hours. Solve the system of equations for b and r to determine the boat's maximum speed in still water and the speed of the river's current.

Jackie needs to save $125 to go to a concert. He has saved $35. He makes $7.50 an hour at his job.
Let x representing the number of hours.
Which equation and solution can be used to show how many hours jackie must work in order to have enough money to go to the concert?
A. 125x + 35 = 750; x = 5.75
B. 35 - 7.5x = 125; x = 6
C. 7.5x + 35 = 125; x = 12
D. 35x + 125 = 750; x = 18
Answer:
C
Step-by-step
Answer:
Answer is C
Step-by-step explanation:
First Jackie needs to save $125
y = 125
He already saved $35, this is our constant
He makes $7.50 an hour on his job,
Our variable x is hours
125 = 7.50x + 35
If we solve for x, we get x = 12

It's X=2
Working out:

2(x+3)=10
2x+6=10
2x=10-6
2x=4
x=2
Working out:
(right one):
2(x+3) must be all divided by 2 so it will be x+3 and same for 10, it will be 5 so...
x+3=5
x=5-3
x=2

The square below represents one whole. Express the shaded area as a fraction, a decimal, and a percent of the whole.
Answer as a fraction = 1/2
Answer as a decimal = 0.5
Answer as a percent = 50%
========================================
Explanation:
There are 5 blue rectangles out of 10 total. This forms the fraction 5/10 and that reduces to 1/2 after dividing both parts by 5. Therefore, the fractions 5/10 and 1/2 are the same. Notice that exactly half of the entire figure is shaded blue.
Use long division or your calculator to find that 1/2 = 0.5 which converts to 50% when you move the decimal point 2 spots to the right.
Answer:
5/10 , 0.5 , 50%

What is the value of 2y- 6 if y = 12
Answer:19
Step-by-step explanation:
The answer is 19 because you need to do 12*2 and then subtract 6. 24-6=19
Answer:
18
Step-by-step explanation:
1.) 2y -6
2 ) 2(12) - 6
3.) 24 - 6
Answer ~ 18
1.) 12 equals y so put 12 in place of y
2.) Using PEMDAS, multiply 12 × 2 which equals 24.
3.) Then you subtract 6 from 24 which equals 18.

Constant of Proportionality
Answer: The constant of proportionality is 8 for the the problem on your left! The constant of proportionality for the one on you right is 6! Hope this helps!
Step-by-step explanation: Vincent earned $24 for 3 hours and so you find out how much he gets paid for 1 hour, then you divide 24 by 3 and get 8! Later he earned $72 for 9 hours, and you do the same thing which is to divide 72 by 9 which also give you 8 and so your unit rate or constant of proportionality is 8. So for the other one Justene can bike for 12 miles in 2 hours and so you find out how many miles she can bike for 1 hours and so you divide 12 by 2 which give you 6 and she can bike 6 miles in 1 hour. Then she biked 36 miles in 6 hours and you divide 36 by 6 which give you 6 and so your constant of proportionality is 6!

write the numerical expression. 6 times the sum of 12 and 8. Write your answer with no spaces.
Answer:
6(12+8)
Step-by-step explanation:
the word 'times' would indicate the multiplication of 2 numbers
the word 'sum' would indicate the addition of 2 numbers. in this case, 12 + 8 would be placed in parenthesis
hope this helps!! :)
