With or without tiles simplify and solve each equation below for x. record your work. a.3x-7=2

Mathematics
1 answer:
AfilCa [17]3 years ago
7 0

Answer:

<u>x=3</u>

Step-by-step explanation:

Addition property of equality is adding the same number to both sides of an equation does not change the equation.

a+c=b+c

3x-7=2

add 7 both sides of an equation.

3x-7+7=2+7

simplify.

3x=9

divide by 3 both sides of an equation.

3x/3=9/3

simplify.

9/3=3

3*3=9

9/3=3

<u>x=3 and 3=x</u>

Hope this helps!

Thanks!

The missing options in the question are:

A. compensation rivalry  B. Demoralization C.  Differential selection

D.  Testing E.  Statistical regression

From the question, we have:

  • September = 99th percentile
  • February = 90th percentile

A change (whether higher or lower) in the score is caused by statistical regression.

This is so because several variables could attribute to the change in the score.

The relationship between these variables is referred to as statistical regression

A store pays $365.84 for a fountain. The store marks up the price by 10%.
Ann [662]

Answer:

The store marks up the fountain by adding $ 36.58 to its original cost, bringing its retail price to $ 402.42.

Step-by-step explanation:

Given that a store pays $ 365.84 for a fountain, and then the store marks up the price by 10%, to determine the amount of the mark-up the following calculation must be performed:

365.84 x 10/100 = X

3,658.4 / 100 = X

36,584 = X

36.584 + 365.84 = 402.424

Thus, the store marks up the fountain by adding $ 36.58 to its original cost, bringing its retail price to $ 402.42.

Solve the equation square root 2x – 7 + x = 5 algebraically, and justify the solution set
yarga [219]

Answer: x=4

Step-by-step explanation:

2x-7+x=5

Group like terms:

\left(2x+x\right)-7=5

Simplify the arithmetic:

3x-7=5

Add 7 to both sides:

3x-7+7=5+7

Simplify the arithmetic:

3x=5+7

Simplify the arithmetic:

3x=12

Divide both sides by 3:

\frac{3x}{3}=\frac{12}{3}

Simplify the fraction:

x=\frac{12}{3}

Find the greatest common factor of the numerator and denominator:

x=\frac{4\cdot 3}{1\cdot 3}

Factor out and cancel the greatest common factor and the answer will be:

x=4
