Answer:
x = 7
Step-by-step explanation:
A triangle's total interior angle measurement will equal 180°.
Set all measurements equal to 180:
(82) + (9x - 6) + (6x - 1) = 180
Simplify. Combine like terms:
(82 - 6 - 1) + (9x + 6x) = 180
(82 - 7) + (15x) = 180
(75) + 15x = 180
Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction

First, Subtract 75 from both sides of the equation:
15x + 75 = 180
15x + 75 (-75) = 180 (-75)
15x = 180 - 75
15x = 105
Next, divide 15 from both sides of the equation:
(15x)/15 = (105)/15
x = 105/15
x = 7
7 is your value for x.

Answer:
4 is in the tenths place. 9 is in the ones. 5 is in the hundredths. 3 is in the thousandths.
117 times 100 11700 then divide by 200 which is 58.5 %
Do what is in the parentheses then add
Answer:
Step-by-step explanation:
<u>The figure consist of:</u>
- 1. A rectangle with sides 10 cm and 17 cm
- 2. A quarter circle
<u>The perimeter is:</u>
- P = 1/4C + 2*10 + 17 + (17 - 8) + 8
- P = 1/4*2*3.14*8 + 54 = 66.56 cm
