Answer:

-4

Step-by-step explanation:

4x+3y=-1

3x + y=-7​

Solve for Y

3x+y=-7

-3x.      -3x

y= -3x - 7

Plug in Y into the top equation

4x + 3 (-3x - 7) = -1

Distribute the Parenthesis

4x -9x-21=-1

Combine Like terms

-5x = 20

Divide by -5 on both sides

20/-5

x = -4

A box is shaped like an octagonal prism. Here is what the base of the prism looks like. If the height of the box is 7 inches, th
Monica [59]

Answer:

The volume of the box is 33.796 cubic inches

Step-by-step explanation:

Given

Height = 7in

See attachment for the base of the prism

Required

The volume of the box

From the attachment, we have:

a = 1in -- side length of the octagon

The area is then calculated as:

Area = 2 * (1 + \sqrt 2)a^2

So, we have:

Area = 2 * (1 + \sqrt 2)* 1^2

Area = 2 * (1 + \sqrt 2)* 1

Area = 2 * (1 + \sqrt 2)

Evaluate the square root

Area = 2 * (1 + 1.414)

Area = 2 * (2.414)

Area = 4.828

The volume is then calculated as:

Volume = Height * Base\ Area

Volume = 7 * 4.828

Volume = 33.796

tino4ka555 [31]

Answer:

62.5%

Step-by-step explanation:

the question is worded weirdly but basically since they're saying "<em>given that a state does not use nuclear power</em>", you can ignore the ones that do use nuclear power.

20 + 12 = 32

and then u have to find the percentage that do use coal (20). to do that all you have to do is divide then move the decimal place backwards 2 times

20 ÷ 32 = 0.625

62.5%

By the definition of complementary angles, since
svlad2 [7]

The blank spaces in the task content can be filled with; Substitution property, 90° and subtraction property.

<h3>What are the missing statements in the proof?</h3>

Since it follows from the vertical angles theorem that angle 1 = angle 4 as they are congruent.

Additionally, angles 1 and 2 are said to be complementary and hence, the sum of their measures is equal to 90°.

Finally, by virtue of the subtraction property of equality, the measure of angle 2 is; 90° - 40° = 50°.
