Based on the lesson, identify the first operation needed to solve the following equation.

DedPeter [7]

Answer:

The first operation is to add, and you are adding 3 to both sides of the equation to isolate the x.

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. You are solving for the variable, x, when solving this equation.

Remember to do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

The first step is to add 3 to both sides of the equation:

(x/3) - 3 (+3) = 11 (+3)

(x/3) = 11 + 3

(x/3) = 14

The second step is to multiply 3 to both sides of the equation:

(x/3) * 3 = (14) * 3

x = 14 * 3

x = 42

42 would be your final answer.

Cylinders A and B are similar solids. The base of cylinder A has a circumference of 4pi units. The base of cylinder B has an

Wittaler [7]

Answer:

d) 9/4

Step-by-step explanation:

<u><em>Explanation</em></u>:-

Given circumference of cylinder A = π r² = 4π units

Given circumference of cylinder B = π r² = 9π units

The dimensions of cylinder A are multiplied by $\frac{9}{4}$

circumference of cylinder A = π r² = 4π( $\frac{9}{4})$ units = 9 π units

circumference cylinder A= 4π( $\frac{9}{4})$ units = 9 π units = circumference of cylinder B

<u><em>Final answer</em></u>:-

<em>The dimensions of cylinder A are multiplied by 9/4 produce the corresponding dimensions of cylinder B</em>
