Answer:

the value of x that makes this equation true is 9

Step-by-step explanation:

2(x - 6) + x + 14 = 4(x - 3) + 5

open the parenthesis

2x - 12 + x + 14 = 4x - 12 + 5

add 12 to both sides of the equation

2x - 12 + 12 + x + 14 = 4x - 12 + 12 + 5

2x + x + 14 = 4x + 5

subtract 5 from both sides of the equation

2x + x + 14 - 5 = 4x + 5 - 5

3x + 14 - 5 = 4x

3x + 9 = 4x

subtract 3x from both sides of the equation

3x - 3x + 9 = 4x - 3x

9 = 4x - 3x

9 = x

check the answer:

2(x - 6) + x + 14 = 4(x - 3) + 5

2(9 - 6) + 9 + 14 = 4(9 - 3) + 5

29 = 29

The length of a rectangle is 2 meters more than its width. The area of the rectangle is 80 square meters. What is the length and

insens350 [35]

Answer:

Step-by-step explanation:

Formula

A = L * W

Givens

W = W

L = W + 2

Solution

Area = L*W

Area = (W+2)*W = 80 Remove the brackets.

Area = W^2 + 2W = 80 Subtract 80 from both sides.

Area = w^2+2W-80=80-80 Combine

Area = w^2 +2W-80 = 0 Factor.

Area = (w+10)(w - 8) = 0

W + 10 = 0 won't work

W = - 10 which isn't possible

W- 8 = 0

W = 8

L = 8 + 2 = 10

The answer looks like A

Ariel made cupcakes to sell. 2/3 of them were chocolate chip,25% of the reminder was strawberry and the rest were 90 vanilla cup

Anton [14]

Answer:

Let x be the total number of cupcakes.

Chocolate chips =

$\frac{2}{3} x$

Strawberry =

$\frac{1}{4} \times \frac{1}{3} \\ = \frac{1}{12} x$

Vanilla =

$x - \frac{2}{3} x - \frac{1}{12}x \\ = \frac{1}{3} x - \frac{1}{12} x \\ = \frac{1}{4} x$

given

$\frac{1}{4} x = 90$

$x = 90 \div \frac{1}{4} \\ = 90 \times 4 \\ = 360$

a)Number of Chocolate chip Cupcakes =

$\frac{2}{3} \times 360 \\ = 240$

b)Number of Strawberry cupcakes =

$\frac{1}{12} \times 360 \\ = 30$

What is the exponential form of root 17

shusha [124]

Answer: $17^{1/2}$

This is 17 to the 1/2 power

The rule is

$\sqrt[n]{x} = x^{1/n}$

the n is the index of the root. For square roots, n = 2, so,

$\sqrt[n]{x} = x^{1/n}\\\\\sqrt[2]{17} = 17^{1/2}\\\\\sqrt{17} = 17^{1/2}\\$
