Answer:
A) 10.00
Step-by-step explanation:
10.00 x 0.8 is equal to 8 giving a total of 18.00. But it is incorrectly done in the table.
Set this up as a ratio putting inches on top and feet on bottom. Then your first ratio would be 1/25 since 1 inch is the same as 25 feet. In between them goes an equals sign and the the other ratio has an x on top (because inches is what we are looking for) and the 1500 on the bottom. Cross multiply to solve for x:
1(1500) = x(25). Divide both sides by 25 to get 60
No it is not because 15 out of 30 is half but 12 out of 20 is more than half
Yes, the coefficients of 12x=48-8y and 10x=38-8y are the same because they are both -8y
Answer: 0.42
60-18= 42
42/100=0.42
(Hope this helped! :D) Stay safe and have a Merry Christmas!!!!!! :D
