Answer:
23h^2
Step-by-step explanation:
These are all like terms so we add/subtract them from left to right.
7h^2+6h^2+5h^2+6h^2-h^2
= 24h^2 - h^2
= 23h^2 (answer)
Answer:
3
Step-by-step explanation:
To turn the word problem into an equation, when we read:
"I am thinking of a number" we write "x"
"when I double my number" we write "2x"
"and then subtract the result from 5" we write "5 - 2x"
"I get negative one" we write "-1 = 5 - 2x"
Now we solve for the number, which is x.
<em>Equation: </em>-1 = 5 - 2x
-1 = 5 - 2x
subtract 5 from both sides
-6 = -2x
divide both sides by -2
3 = x
<h3>
There we go! The number is </h3><h2>
3</h2>
