Step-by-step explanation:
Step 1: Define equation
5(x - 8) = 20
Step 2: Solve for x
Divide 5 on both sides: x - 8 = 4Add 8 on both sides: x = 12Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 5(12 - 8) = 20Subtract: 5(4) = 20Multiply: 20 = 20Here we see that 20 does indeed equal 20.
∴ x = 12 is a solution to the equation.

distance between A (2, -1) and (2,a) is 4 units. Find the value of a where a is positive.
Answer:
a = 3
Step-by-step explanation:
Calculate the distance d using the distance formula and equate to 4
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (2, - 1) and (x₂, y₂ ) = (2, a)
d = [tex]\sqrt{(2-2)^2+(a+1)^2}[/tex] = [tex]\sqrt{0+(a+1)^2}[/tex] = [tex]\sqrt{(a+1)^2}[/tex] = a + 1 then
a + 1 = 4 ( subtract 1 from both sides )
a = 3
whatis the value of y?
Answer:
Finding the y value is easy if you know the slope of the line and the x coordinate. Review the equation for the slope of a line. The equation for finding the slope is: m = [y1 - y2] / [x1 - x2]. If you know x, you can solve for y to find the y value for the slope of the line.

Abbie paints twice as fast as beth and three times as fast as cathie. If it takes them 60 min to paint a living room with all three working together, how long would it take abbie if she works alone?
Abbie takes 110 minutes t complete painting work alone.
How Abbie take 110 minutes to complete painting work alone?Let x= time takes Abbie to paint the room
1 minute =1/x part the of room painted paint by Abbie paint the room
2x minute times takes both to paint the room
so, in 1 minute 1/2x part of the room paint by Abbie and Beth
Abbie paints three times faster than Cathie
Cathie takes 3x minutes take time to paint the room.
in 1 minute 1/3x part of room paint by Cathie
they take 60 minute to paint a room all three working together
in 1minute 1/x+ 1/2x+ 1/3x parts
in 60 minute = ( 1/x+1/2x+ 1/3x) 60 =1 room
= [tex]\frac{6x+3x+2x}{6x^{2} } 60[/tex] = 1
= [tex]\frac{11x}{6x^{2} } 60[/tex] = 1
x = 110 minute

What is x? -4(x+2)=4(2-2x)
Answer:
x = 4
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
-4(x + 2) = 4(2 - 2x)
Step 2: Solve for x
Divide -4 on both sides: -(x + 2) = 2 - 2xDistribute negative: -x - 2 = 2 - 2xAdd 2x on both sides: x - 2 = 2Add 2 on both sides: x = 4Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -4(4 + 2) = 4(2 - 2(4))Multiply: -4(4 + 2) = 4(2 - 8)Add/Subtract: -4(6) = 4(-6)Multiply: -24 = -24Here we see that -24 does equal -24.
∴ x = 4 is the solution to the equation.

Josiah is 5 years older than Alexis. In 7 years the sum of their ages will be 85. How old is Josiah now?
Can you help me solve it!!
Answer:
Step-by-step explanation:
Alexis is X years old
Josiah is X + 5 years old
in 7 years:
Alexis is x + 7 years old
Josiah is x + 5 + 7 => x + 12 years old
Sum of their ages is 85 :
x + 7 + x + 12 = 85
2x + 19 = 85
2x = 85 - 19 = 66
x = 66/2 = 33 => Alexis age
Josiah is x + 5 = 33 + 5 = 38 years old
Todd swam three trials of the 50-meter freestyle. His time was 32.15 seconds for the first trial, 31.67 seconds for the second trial, and 30.55 seconds for the third trial. Part A What is Todd's combined time for all three trials? Enter your answer in the box. seconds Part B How much faster was Todd's second trial than his first trial? Enter your answer in the box. second(s)
Answer:
A. 94.37 seconds
B. 0.48 seconds
Step-by-step explanation:
Total distance = 50 meters
First trial = 32.15 seconds
Second trial = 31.67 seconds
Third trial = 30.55 seconds
A. What is Todd's combined time for all three trials
Todd's combined time for the three trials = First trial + Second trial + Third trial
= 32.15 seconds + 31.67 seconds + 30.55 seconds
= 94.37 seconds
B. How much faster was Todd's second trial than his first trial?
Second trial = 31.67 seconds
First trial = 32.15 seconds
Time taken for first trial - Time taken for second trial -
= 32.15 seconds - 31.67 seconds
= 0.48 seconds
Todd's second trial was 0.48 seconds faster than his first trial

What value would you add to this expression to make a perfect square? x²+x
Answer:
we would add [tex]\:\left(\frac{1}{2}\right)^2\:[/tex] or 1/4 to make the expression a perfect square.

Given the expression
[tex]x^2+x[/tex]
[tex]\mathrm{Write}\:x^2+x\:\mathrm{in\:the\:form:\:\:}x^2+2ax+a^2[/tex]
[tex]2a=1[/tex]
Divide both sides by 2
[tex]\frac{2a}{2}=\frac{1}{2}[/tex]
[tex]a=\frac{1}{2}[/tex]
as
[tex]x^2+2ax+a^2=\left(x+a\right)^2[/tex]
[tex]\mathrm{Add\:}\:\left(\frac{1}{2}\right)^2\:[/tex]
[tex]x^2+1x+\left(\frac{1}{2}\right)^2=\left(x+\frac{1}{2}\right)^2[/tex]

how many 7-digit numbers are there where all the digits are different and in increasing order? for example, the numbers 1345689 and 2456789 would be counted. (the first digit cannot be zero.) (a) 20 (b) 24 (c) 28 (d) 32 (e) 36
There are 544,320 7-digit numbers that are all unique and arranged in increasing order.
We apply the Fundamental Counting Principle to this issue. You are aware that a number has seven digits. According to this theory, you must multiply the potential integers for each digit. There are 9 potential numbers if the initial number can't be zero. Consequently, the first digit's value is 9. Any number, but less than 1, could be used for the second digit since it was already used in the first. Thus, 10 – 1 would equal 9. The value in the third digit must be less than 1 and in the second digit. In this case, 9 – 1 Equals 8. And the list goes on.
Therefore, the number of seven-digit numbers in which all digits are different and in increasing order is:
9 × 9 × 8 × 7 × 6 × 5 × 4 = 544,320
Hence, there are 544,320 7-digit numbers with all different digits in increasing order.
