<u>burned: </u>756 calories
<u>hours:</u> 3
same number of calories each hour
-> to find this, we must split the number of calories evenly among the hours
<u>steps</u>
756/3
= 252 calories per hour
You have to draw the numbers then you would have to divide them draw it
Answer:
B- 583
Step-by-step explanation:
6% of 550 is 33. So, you just add 33 to 550 which equals 583.
Your welcome!
Since you need an isolated variable to use the substitution method, we need to re-arrange one of the equations. This will probably be easiest to do with the first one.
Add 5y to both sides of the first equation.
x=10+5y
Now, in the second equation, put in 10+5y in any spot that has an x.
2(10+5y)-10y=20
Distribute the 2 to both numbers in the parenthesis.
20+10y-10y=20
Combine like terms.
20=20
This means that the two equations are actually the same. You can see this if you multiply the whole first equation by 2
2(x-5y=10)
2x-10y=20, which is the same as the second equation. Therefore, the two equations are actually the same one.
