Answer:
x = 4
Step-by-step explanation:
Step 1: Write out equation
3x + 6 = 18
Step 2: Subtract 6 on both sides
3x = 12
Step 3: Divide both sides by 3
x = 4
Answer:
4
Step-by-step explanation:
3x +6 =18
3x =18 - 6
3x =12
x =12 :3
x =4
The price of apples can be determined by the equation P = 0.23n, where P is the price and n is
the number of apples. What is the constant of proportionality (unit rate)?
Answer:
0.23
Step-by-step explanation:
Basically, the unit rate is how much its increasing every time you add on. So if it were 2+2+2 the unit rate would be 2! Hope this helps!
3x(x+30°) i really need help asap
A13x2+390x here is the answer
Answer:
x=15
Step-by-step explanation:
Simplifying
x + 30 = 3x
Reorder the terms:
30 + x = 3x
Solving
30 + x = 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
30 + x + -3x = 3x + -3x
Combine like terms: x + -3x = -2x
30 + -2x = 3x + -3x
Combine like terms: 3x + -3x = 0
30 + -2x = 0
Add '-30' to each side of the equation.
30 + -30 + -2x = 0 + -30
Combine like terms: 30 + -30 = 0
0 + -2x = 0 + -30
-2x = 0 + -30
Combine like terms: 0 + -30 = -30
-2x = -30
Divide each side by '-2'.
x = 15
Simplifying
x = 15
find the value of each power 5^-2
Answer:
5⁻² = 1/25
3⁴ = 81
Step-by-step explanation:
5⁻² = 1/5² = 1/25 3⁴ = 3² * 3² = 9*9 = 81Write an algebraic expression that represents the following statement: “7 less than the quotient of 5 and n" *
[tex]\huge\boxed{\boxed{\bold{\frac{5}{n}-7}}}[/tex]
[tex]\hrulefill[/tex]
We'll start with the expression for the quotient of [tex]5[/tex] and [tex]n[/tex], which means we'll use division:
[tex]\frac{5}{n}[/tex]
Now we find [tex]7[/tex] less than that, meaning we'll use subtraction:
[tex]\frac{5}{n}\bold{-7}[/tex]

To ensure profits, a store is going to sell a sweater for 115 percent of the production cost. It costs $10 to make the sweater. Below are the calculations for finding the selling price. What mistake did the store owner make? (Original Cost)(Percent) = New Cost ($10)(0.115) = $1.15 The new cost is correct. The owner should have divided by 0.115. The owner should have multiplied by 11.5. The owner should have multiplied by 1.15.
Answer:I did the test and the answer is The owner should have multiplied by 1.15.
Step-by-step explanation:
Sample text
To make the calculation 115 percent of the production cost , the owner should have multiplied by 1.15 to the production cost.
What is percentage?" Percentage is defined as the hundredth part of any given number".
According to the question,
Production cost of a sweater = $10
To ensure profit , selling price = 115 percent of the production cost
(Original Cost)(Percentage)
[tex]= (10)(\frac{115}{100} )[/tex]
[tex]= $11.5[/tex]
Hence, to make the calculation 115 percent of the production cost , the owner should have multiplied by 1.15 to the production cost.

Answer:
x = 5
Step-by-step explanation:

4x - 6 = x + 9
4x - 6 - x - 9 = x + 9 - x - 9 [Subtract x + 9 from both sides]
3x - 15 = 0
3x - 15 + 15 = 0 + 15 [Add 15 to both sides]
3x = 15
3x/3 = 15/3 [Divide both sides by 3]
