Answer:

2x = 10

Step-by-step explanation:

7 + 3x = 22

-7 -7

Subtract 7 from both sides (you are trying to get the variable alone, and to do that, you have to get every other number to 0. <em>7 - 7 = 0</em>. BUT, whatever you do, you have to do to both sides.)

3x = 15

/3 /3

Divide both sides by three to get the variable alone.

x = 5

Now, plug in the value of x to the second equation and solve.

2(5) = ? --> 10

Find the value of x by using law of sines.

Pavel [41]

Answer:

x = 7.7

Option B

Step-by-step explanation:

$\frac{a}{Sin~A} &=& \frac{b}{Sin~b} \\ \frac{8}{Sin~73^\circ} &=& \frac{x}{Sin~67^\circ} \\ \frac{8}{0.96} &=& \frac{x}{0.92} \\ 0.96x &=& 8 \times 0.92 \\ 96x &=& 8 \times 92 \\ 96x &=& 736 \\ x &=& \frac{736}{96} \\ x&=& \frac{23}{3} \\ &\boxed{x=7.7}&$

∴ value of x is 7.7

HELP! I DONT UNDERSTAND AND ITS DUE IN A BIT!!

DIA [1.3K]

Answer: It is a 90 Clockwise Degree Turn.

Step-by-step explanation:

From my knowledge, a 90-degree turn is a turn to the right.

So if you turn the "C" in the Y-axis 90 degrees you will get The "C" on the X-axis.

For Example: When you walk around a street you either turn 90 degree's to the right or 90-degrees to the left.

Hope this Helps!

Answer:

C) 120 square feet

Step-by-step explanation:

Note that the bed is in the shape of a <em>triangle</em>. You are also finding the area of the bed (Use the formula Area = 1/2(base * height)).

The base = 20, height = 12. Plug in the corresponding numbers to the corresponding variable.

A = 1/2(20)(12)

Simplify.

A = 1/2(20)(12)

A = (20 * 12)/2

A = (10 * 12)

A = 120

C) 120 square feet is your answer.

*Good luck!
