Easy points
goblinko [34]

Answer: 2

Step-by-step explanation:

try each value in the equation

2(0) + 1 = 3

0 + 1 = 3

1 ≠ 3

so 0 doesn’t work

2(1) + 1 = 3

2 + 1 = 3

3 = 3

this works, so the answer is 1

What is the value of x?<br>30<br>45<br>55<br>60​
KATRIN_1 [288]

Answer:

\boxed {\tt B. \ x=45}

Step-by-step explanation:

x and 3x are on a straight line together. Therefore, they are supplementary and must add to 180 degrees.

Add x and 3x, and set that equal to 180.

x+3x=180

Combine like terms on the right side of the equation. Both x and 3x have a variable, so they can be added together.

(x+3x)=180

4x=180

Since we want to find x, we have to isolate x. x is being multiplied by 4. The inverse of multiplication is division. Divide both sides of the equation by 4.

\frac{4x}{4} =\frac{180}{4}

x=\frac{180}{4}

x=45

x is equal to 45, so the correct answer is B. 45

Raise 2 to the 4th power, then add r to the result
Oxana [17]

Answer:

2⁴ + r

Step-by-step explanation:

Change the sentence into a expression.

Note that r is a variables.

"Raise 2 to the 4th power..." means 2 to the 4th power, or 2⁴.

"...then add r to the result" means: + r

Combine the two terms:

2⁴ + r is your answer.

~

Simplify if need be.

2⁴ = 2 * 2 * 2 * 2 = 4 * 4 = 16

r + 16 is your answer.
