just number 7 would be fine but if you could also number 8 would help a lot
Answer:
7. r = -5
8. x = -1
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
r + 2 - 8r = -3 - 8r
Step 2: Solve for r
Combine like terms: -7r + 2 = -3 - 8rAdd 8r to both sides: r + 2 = -3Subtract 2 on both sides: r = -5Step 3: Check
Plug in r into the original equation to verify it's a solution.
Substitute in r: -5 + 2 - 8(-5) = -3 - 8(-5)Multiply: -5 + 2 + 40 = -3 + 40Add: -3 + 40 = -3 + 40Add: 37 = 37Here we see that 37 does indeed equal 37.
∴ r = -5 is a solution of the equation.
Step 4: Define equation
-4x = x + 5
Step 5: Solve for x
Subtract x on both sides: -5x = 5Divide -5 on both sides: x = -1Step 6: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -4(-1) = -1 + 5Multiply: 4 = -1 + 5Add: 4 = 4Here we see that 4 does indeed equal 4.
∴ x = -1 is a solution of the equation.

Solve for the y intercept and then for the x intercept .
4x+5y=20
**ALSO DON’T ANSWER IF YOU WONT SHOW YOUR STEPS ****
Answer:
20 is the y-intercept, 0 is the x-intercept.
Step-by-step explanation:
How I learned:
I was taught that the formula is y=ax+b
b is the one without a variable next to it, so 20 is b.
0 is the x intercept because, I don't know how to explain it well, but 0 is the only x value that touches the x line.
The x-intercept and the y-intercept are both the points that touch the x/y line, depending on the equation.
Hope this helped!
(P.S. 0 is always the x-intercept)

Step-by-step explanation:
1. Slope= 3/4x (MAKE SURE TO PUT THE X) Y intercept = +7 (MAKE SURE YOU PUT A + IF IT IS POSITIVE AND - IF NEGATIVE
2. Slope = 5x Y intercept = 8 (I think this was a trick question?)
3. Slope = -2x Y intercept = 0 (So just keep it empty or say 0 if your teacher is like that)
4. Slope = x Y intercept = +12

On their previous exam, Rhea answered 58 on the question correctly and Precious answered 711 of it correctly. If each problem is worth the same amount, who got the higher score?
Answer:
Precious
Step-by-step explanation:
Here is the correct question used :
On their previous exam, Rhea answered 5/8 on the questions correctly and Precious answered 7/11 of it correctly. If each problem is worth the same amount, who got the higher score?
To determine who got the higher score, we can convert the fractions into percentages
Rhea = 5/8 = 5/8 x 100 = 62.5%
Precious = 7/11 x 100 = 63.6%
63.6% is greater than 62.5%. So, Precious had the higher score

Over a one week period in the summer, the price of a gallon of gas increased from $2.35 to $2.82. By what percent did the price of gas increase over that week?
A
10%
B
20%
C
30%
D
40%
Answer:
B
Step-by-step explanation:
The price of gas increases from $2.35 to $2.82 or by $0.47 ($2.82 - $2.35 = $0.47).
The increase as a percentage of the original price is given by
($0.47/$2.35) x 100% = 20%
The price of gas increase over that week by 20%.
PercentagePercentage are numbers or ratios which are being expressed in fraction of 100.
Percentage change = (change in price / original price) * 100%
Change in price = Final price - original price
From the question:
Change in price = 2.82 - 2.35 = 0.47Percentage change = (0.47 / 2.35) * 100% = 20%
The price of gas increase over that week by 20%.

Hi there!
Question:
What is the value of x in the equation 2 (6x+4) - 6 + 2x = 3 (4x + 3) + 1
Answer:
x = 4
Step-by-step explanation:
[tex]2(6x+4) -6+2x=3(4x+3)+1[/tex]
Step 1: Simplify both sides of the equation.
[tex]2(6x+4)-6+2x=3(4x+3)+1[/tex]
[tex](2)(6x)+(2)(4)+-6+2x=(3)(4x)+(3)(3)+1[/tex] (Distribute)
[tex]12x+8+- 6+2x=12x+9+1[/tex]
[tex](12x+2x)+(8+- 6)=(12x)+(9+1)[/tex] (Combine Like Terms)
[tex]14x+2=12x+10[/tex]
Step 2: Subtract 12x from both sides.
[tex]14x+2 -12x=12x+10 - 12x[/tex]
[tex]2x+2=10[/tex]
Step 3: Subtract 2 from both sides.
[tex]2x+2-2=10-2[/tex]
[tex]2x=8[/tex]
Step 4: Divide both sides by 2.
[tex]\frac{2x}{2} =\frac{8}{2}[/tex]
[tex]x=4[/tex]
