Answer:
5 1/4
Step-by-step explanation:
5 is the whole number so we up it aside.
Then we are left with 25/100,when we simplify that 25 into 25 is 1.
25 into 100 is 4 times.
Therefore we are left with 1/4.
I hope this helps :)
Answer:
The Type of Drink (Gatorade or Water)
Step-by-step explanation:
The Independent variables which causes the measured difference or change in the output of the dependent variable. In an experiment, the treatment administered to subjects which will most likely result into differing output are called the independent variables. In the scenario described above, the independent variable is the type of drink taken by the athlete, this drink will cause a change on the output, (how far an athlete can run) which is the dependent variable in the experiment.
To answer this kind of question, you need to insert the first equation into second equation or vice versa. The equation from the question should be:
1. 3 paperback books + 5 hardcover book = $80.10
2. 7 paperback books + 4 hardcover book= $100.65
It would be easier to convert the 1st equation into
5 hardcover book = $80.10- 3 paperback books
hardcover book= $16.02- 0.6 paperback books
Then insert it to 2nd equation:
7 paperback books + 4 ($16.02- 0.6 paperback books)= $100.65
7 paperback books + $64.08- 2.4 paperback books= $100.65
4.6 paperback books = $100.65- $64.08= $36.57
paperback book= $7.95
Insert paperback book price to the first equation to find the hardcover book price
3 paperback books + 5 hardcover book = $80.10
3 ($7.95)+ 5 hardcover book = $80.10
5 hardcover book = $80.10 - $23.85= $56.25
hardcover book = $11.25
Then one paperback and one hardcoverbook= $7.95 + $11.25= $19.20
