Answer:
x = 21
Step-by-step explanation:
<u>Step 1: Make an expression</u>
Since they are supplements, that means that they add up to 180 degrees.
3x + 6 + 5x + 6 = 180
<u>Step 2: Combine like terms</u>
3x + 6 + 5x + 6 = 180
(3x + 5x) + (6 + 6) = 180
8x + 12 = 180
<u>Step 3: Subtract 12 from both sides</u>
8x + 12 - 12 = 180 - 12
8x = 168
<u>Step 4: Divide both sides by 8</u>
8x / 8 = 168 / 8
x = 21
Answer: x = 21
<u>Answer:</u>
<u>333×2+999-999÷2= 333</u>
<u>Step-by-step explanation:</u>
Answer:
d = 6
Step-by-step explanation:
We know that the radius is 3m and we need to find the diameter.
The formula for the diameter is d = 2r
Since the radius is 3, we can substitute r for 3.
d = 2(3)
d = 6
