Answers:
1) -3(x + 8) = -21
2) Division Property of Equality
3) x + 8 = 7
4) Subtraction Property of Equality
Reasoning:
You are already given the equation, so that will be #1 in the Given.
#2 shows both sides being divided by -3, so you will put the Division Property of Equality.
#3 shows the Division Property after it is carried out, so you will put the equation after the division is done.
#4 shows you are subtracting 8 from both sides, so put the Subtraction Property of Equality.
Answer:14.7
Step-by-step explanation:
d = l^2+w^2+h^2 = 10^2+4^2+10^2≈ 14.69694cm
Thirty six divided by four is equal to nine
To figure this out you can do 7.2/8.2, because you are trying to figure out how much of the total was used, and percentages would not be more than 100%. Doing this you would get ~.878. To convert this to a percent, you would just multiply it by 100, which would give you 87.8%. The question states to round to the nearest whole percent, leaving you with 88%. This means that 88% of the revenue was spent.
Hope that helped, don't be shy to comment on this if you have any questions about my explanation :)
