evaluate 36 / x + 9 when x equals 3
Answers
Answer:
3.Step-by-step explanation:
Given equation:
36 ÷ x + 9Given variables:
x = 3.Solve:
36 ÷ x + 9= 36 ÷ 3 + 9= 36 ÷ 12= 3.Multiply all terms by x and cancel:
36+9x=3x
9x+36=3x
(Simplify both sides of the equation)
9x+36−3x = 3x−3x
(Subtract 3x from both sides)
6x+36 = 0
6x+36−36 = 0−36
(Subtract 36 from both sides)
6x = −36
6x/6 = −36/6
(Divide both sides by 6)
x = −6
Check answers. (Plug them in to make sure they work.)
x = −6

Step-by-step explanation:
Before we begin, the question tells us that angle JKL is a right angle. A right angle means the angle is 90 degrees. It tells us that one of the angle is 35 degrees and another is x. Since they make up a right angle, 35 plus x should equal to 90. To find x, subtract 35 from 90 and you get 55.

A vintage wheel needs to be banded with an iron strip. If the wheel’s radius is 11 inches, how long must the iron strip be to go all the way around the wheel? Complete the steps below to answer the question.
Answers
Answer:
Step-by-step explanation:
first lets find the circumference of the wheel:
[tex]C=\pi *d[/tex]
we have to find the diameter out of the radius:
[tex]d=r*2[/tex]
because the radius is half of the diameter, intrhis case i have to findf the diameter so i do multiply it with 2:
[tex]r=11\\d=??\\d=11*2\\d=22[/tex]
we found the diameter now we are going to find the circumference :
[tex]C=\pi *d\\C=\ 3.14*22\\C= 69.08[/tex]
Another way (easier)to find the circumference is:
[tex]C=2\pi *r\\C=2(3.14)*11\\C=69.08[/tex]
At the end it will hav ethe same answer.
Answer:
69.08 inches
Step-by-step explanation:
substitute the values of r (11 inches) and pi (3.14) in the formula c = 2πr to find c:
c = 2 × 3.14 × 11 inches
c = 69.08 inches.
the circumference of the wheel is about 69.08 inches.
