Answer:
9 is your answer for x.
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Do the opposite of PEMDAS.
PEMDAS is the order of operations, & =
Parenthesis
Exponent (& Roots)
Multiplication
Division
Addition
Subtraction
First, subtract 13 & 8x from both sides:
2x (-8x) + 13 (-13) = 8x (-8x) - 41 (-13)
2x - 8x = -41 - 13
Simplify. Combine like terms:
-6x = -54
Isolate the variable, x. Divide -6 from both sides:
(-6x)/-6 = (-54)/-6
x = (-54)/(-6)
x = 9
x = 9 is your answer.

Answer:
39 apples
Step-by-step explanation:
45 is 3/4 or 75% of an hour. So, multiply 52 by 75% to find the answer.
75% ÷ 100 = 0.75
52 x 0.75 = 39
Answer:
We have z - 8 = 4 or z - 8 = -4;
Then, z = 12 or z = 4;
The correct answer is d).
Step-by-step explanation:
Hello!
The formula for finding area of a circle is: π · r²
Diameter is 2x the radius. To find the radius when the diameter is given, divide the diameter by 2.
The diameter is 13. 13 ÷ 2 = 6.5
r = 6.5
6.5² = 6.5 × 6.5 = 42.25
π = 3.14
Multiply 3.14 by 42.25 to get the area
3.14 × 42.25 = 132.665
<em>The area of the circle is 132.665 sq. units, which is the last option.</em>
