Answer: x=4

Step-by-step explanation:

Simplifying

(14x + -15) + 139 = 180

Reorder the terms:

(-15 + 14x) + 139 = 180

Remove parenthesis around (-15 + 14x)

-15 + 14x + 139 = 180

Reorder the terms:

-15 + 139 + 14x = 180

Combine like terms: -15 + 139 = 124

124 + 14x = 180

Solving

124 + 14x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-124' to each side of the equation.

124 + -124 + 14x = 180 + -124

Combine like terms: 124 + -124 = 0

0 + 14x = 180 + -124

14x = 180 + -124

Combine like terms: 180 + -124 = 56

14x = 56

Divide each side by '14'.

x = 4

Simplifying

x = 4

What is not a description of slope?

Gelneren [198K]

Answer:

Option (d) is wrong.

Step-by-step explanation:

Slope is:

rise over run
The rate of change of a line
Change in y over the change in x
<em><u>The ratio of vertical change to the horizontal change. </u></em>

It can be given by mathematically as follows :

$m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{and}\\\\m=\dfrac{dy}{dx}$

Hence, the option which is not a description of slope is (d) "the ratio of horizontal change compared to vertical change"

You want to give your friend a soccer ball for a gift. The soccer ball has a

Ede4ka [16]

Answer:

volume of cube share box = 67.92 inch²

Step-by-step explanation:

given data

soccer ball volume = 85.3π cubic inches

solution

we know that ball will fit inside the box when box length will be equal to diameter of ball

and here soccer ball volume will be express as

soccer ball volume = $\frac{4}{3}\times \pi \times r^3$ .................1

85.3π = $\frac{4}{3}\times \pi \times r^3$

solve it we get

r³ = 69.9765

r = 4.12 inch

so diameter = 2 × 4.12 = 8.24 inch

diameter = length of box side

volume of cube share box = a²

volume of cube share box = 8.24²

volume of cube share box = 67.92 inch²
