Answer:
7.0 < x < 7.6
X is the ideal pH of the swimming pool
If you were to correctly simplify this equation, the answer would be a negative.
The answer is: n = -5
Here's how I got my answer:
Step 1: Add 3 to both sides. Which leaves us with 
Step 2: Simplify
to 45. Which leaves us with 
Step 3: Divide both sides by -9. Which leaves us with 
Step 4: Simplify
, to get your answer, n = -5.
165,827 and 165,229
the hundreds spot in the first number is 8 while in the second number the hundreds spot is only two
Use substitution.
2p + 3(2p) = 680
2p + 6p = 680
8p = 680
p = 85
Plug in.
x = 2p
x = 2(85)
x = 170
p = 85
Answer:
2
Step-by-step explanation:
(10+10-4)÷8 is your expression.
10+10=20
20-4=16
16/8=2
