Solve the equation for the given variable.
-2 (x + 6) = 8

Answers

Answer 1

Answer:

x = -10

Step-by-step explanation:

-2 (x + 6) = 8

-2x + -12 = 8

+12 +12

-2x = 20

÷ -2 ÷ -2

x = -10

Answer 2
Answer:
x=10

STEP BY STEP EXPLANATION:

1. distribute -2(x+6) to get a total of -2x+-12
2. Add 12 on both sides and you’re left with -2x=20
3. Now you divide -2 on both sides.., now you’re left with x=10

Answer:

B

Step-by-step explanation:

Given that the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{AB}{DE}[/tex] = [tex]\frac{BC}{EF}[/tex] , substitute values

[tex]\frac{35}{5}[/tex] = [tex]\frac{42}{x}[/tex] ( cross- multiply )

35x = 210 ( divide both sides by 35 )

x = 6 → B

Three quarts of a latex enamel paint will cover about 120 square feet of wall surface. How many quarts are needed to cover 161 square feet of kitchen wall and 119 square feet of bathroom​ wall? Nothing quarts of a latex enamel paint are required

Answers

Answer:

7 quarts

Step-by-step explanation:

We can solve this problem by using the rule of three. As seen in the picture below we need to find the X. We do this by multiplying 161 sq. ft. diagonally by 3 quarts and then dividing by 120 sq. ft. This will give us the number of quarts needed for the kitchen wall. Then we simply repeat the process for the bathroom wall and we are done. Like so ...

[tex]\frac{161 sq. ft. * 3 quarts}{120 sq. ft.} = x[/tex]

[tex]4.025 quarts = x[/tex]

[tex]\frac{119sq. ft. * 3 quarts}{120 sq. ft} = x[/tex]

[tex]2.975 quarts = x[/tex]

Therefore we need 4.025 quarts for the kitchen wall and 2.975 quarts for the bathroom wall ... making that a total of 7 quarts.

On a coordinate plane, a line is drawn between point (x 2, y 2) and (x 1, y 1). Which equation would find the distance between the two points show on the coordinate plane? d = StartRoot (x 2 + x 1) squared + (y 2 + y 1) squared EndRoot d = StartRoot (x 2 minus x 1) squared minus (y 2 minus y 1) squared EndRoot d = StartRoot (x 2 minus x 1) squared + (y 2 minus y 1) squared EndRoot

Answers

Answer:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Step-by-step explanation:

Given: A line is drawn between points [tex](x_2,x_1)\,,\,(y_2,y_1)[/tex]

To find: distance between the two points

Solution:

A coordinate plane is a two-dimensional plane formed by the intersection of a  y-axis and x-axis. x-axis and y-axis are perpendicular lines that intersect each other at the origin.

Let d denotes distance between the two points [tex](x_2,x_1)\,,\,(y_2,y_1)[/tex]

Use the formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

The distance between the two points show on the coordinate plane is D = √[(x₂-x₁)²+(y₂-y₁)²]. Therefore, the correct answer is option C.

The given coordinate points are (x₁, y₁) and (x₂, y₂).

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula.

On 2D plane the distance between two points (x₁, y₁) and (x₂, y₂) is

Distance = √[(x₂-x₁)²+(y₂-y₁)²].

Therefore, the correct answer is option C.

Star A is about 3.4 x10^18 miles from earth. star B is 6.8 x 10^16 miles from earth.Star A is how many times as far from Earth as Star B? I

Answers

Answer: It's 50

Step-by-step explanation:

3.4 divided by 6.8 is 0.5 and 18-16 (the exponents) is 2. since ur dividing your subtracting the exponents. so then u get 0.5*10^2 but it cant be lower than 1 so u move the decimal in 0.5 one space to the right which then leads you to get 5*10^1 or 5*10 which is 50.

how to solve this 58+5x+10=11x+2

Answers

Answer:

11 = x

Step-by-step explanation:

58+5x+10 = 11x+2

68+5x = 11x+2

    -5x = -5x

68 = 6x+2

-2          -2

66 = 6x

66/6 = 6x/6

11 = x

Hope this helps!

Answer:

x = 11

Step-by-step explanation:

58 + 5x + 10 = 11x + 2

First, combine like terms

68 + 5x = 11x + 2

Subtract 5x from both sides of the equation

68 = 6x + 2

Subtract 2 from both sides of the equatino

66 = 6x

Divide both sides by six to get your answer

11 = x

Which is correct equation , in slope intercept form , for the line described below?


x-intercept =-2
Y-intercept=6

Answers

Answer:

[tex]y=3x+6[/tex]

Step-by-step explanation:

Equation of the line

The equation of the line in slope-intercept form is:

[tex]y=mx+b[/tex]

Being m the slope and b the y-intercept.

We are given two points for the required line: The x-intercept is -2, thus the point is (-2,0), and the y-intercept b=6 represents the point (0,6).

Since the value of b is 6, we use the first point to find the slope:

[tex]0=m(-2)+6[/tex]

Solving:

m=3

The correct equation of the line is:
