Solve the equation: x-10 - 2x + 7 = 8 + x - 10 - 3x

Minchanka [31]

Answer: If you're looking for the value of x, it's 1.

Step-by-step explanation:

Add the numbers. x-10-2x+7=8+x-10-3x--->x-3-2x=8+x-10-3x

Combine like terms. x-3-2x=8+x-10-3x ---> -x-3=8+x-10-3x

Subtract the numbers.-x-3=8+x-10-3x---> -x-3=-2+x-3x

Combine like terms. -x-3=-2+-3x---> -x-3=-2-2x

Rearrange terms. -x-3=-2-2x---> -x-3=-2x-2

Hope that helps!

Write an equation to find the number of students in Mr. Boggs' homeroom if the total number of students is 90.

gladu [14]

Answer:

15(b+2) + 15 + 2b-9 +b = 90

Step-by-step explanation:

Essentially you add up all of the values and make it equal to 90, then solve for b

15(b+2) + 15 + 2b-9 +b = 90

15b + 30 + 15 + 2b - 9 + b = 90

18b + 30 + 15 - 9 = 90

18b + 36 = 90

18b = 54

b=3

Line w and line v are perpendicular to each other. Line w passes through the points ( -4,8 ) and ( 12,-2 ). What is the slope of

erik [133]

The slope of line "v" is $\frac{8}{5}$

<h3><u>Solution:</u></h3>

Given that Line w and line v are perpendicular to each other

Also given that line w passes through the points ( -4, 8 ) and ( 12, -2 )

To find: slope of line v

Since line w and line v are perpendicular to each other, product of slopes of line w and line v are equal to -1

$\text {slope of line } w \times \text { slope of line } v=-1$ ---- eqn 1

Let us first find slope of line w

<em><u>The slope "m" of a line is given as:</u></em>

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$\text {Here } x_{1}=-4 \text { and } x_{2}=12 \text { and } y_{1}=8 \text { and } y_{2}=-2$

$m=\frac{-2-8}{12-(-4)}=\frac{-10}{16}=\frac{-5}{8}$

Thus the slope of line "w" is $\frac{-5}{8}$

Substituting the slope of w in eqn 1 we get,

$\begin{array}{l}{\frac{-5}{8} \times \text { slope of line } v=-1} \\\\ {\text { slope of line } v=\frac{8}{-5} \times-1=\frac{8}{5}}\end{array}$

Thus the slope of line "v" is $\frac{8}{5}$

Help ASAP 20 POINTS Zayn is making a centerpiece for his dining room table by putting sand in a cube shaped vase. The case is 0.

denis-greek [22]

Answer:

23.52 m^3

Step-by-step explanation:

The volume of sand purchased by Zayn is independent of the shape or dimension of the vase he is making.

The volume V is simply given by the divisor of the mass of sand purchased (m= 25 kg) by the density (d=1.063 kg/m^3).

V = m/d= 25/1.063= 23.52 cubic meters
