Answer: "Subtract 6 from both sides, and then divide by 2. The solution is x = 8"
Step-by-step explanation: Lets solve for 2x + 6 = 22
Step 1 Subtract 6 from both sides: 2x + 6 - 6 = 22 - 6 2x = 16
Step 2 Divide by 2 in both sides: 2x/2 = 16/2
Step 3 The answer: x = 8
Answer:
or
Step-by-step explanation:
First we will convert the first term into an improper fraction. We multiply the whole number into the denominator and add the product to the numerator.
Then we will multiply the first term by 4/4 to match the denominator of the second term..
* =
Finally we subtract.

Answer:
Both Ivy and Andrey
Step-by-step explanation:
-100, -50, 0, 50 is an arithmetic sequence, because it has a common difference:
-50 − (-100) = 50
0 − (-50) = 50
50 − 0 = 50
The first term is -100 and the common difference is 50, so:
f(n) = -100 + 50 (n − 1)
Simplifying:
f(n) = -100 + 50n − 50
f(n) = -150 + 50n
So both Ivy and Andrey are correct.
Answer:
x = 45
Step-by-step explanation:
0.36(18) + 0.04x = 0.12(24 + x)
6.48 + 0.04x = 2.88 + 0.12x
0.04x - 0.12x = 2.88 - 6.48
-0.08x = -3.6
0.08x = 3.6
x = 3.6/0.08
x = 45
