Can you tell us the dimensions of the trapezoid so we can help you?
7+3 = 10
30/10 = 3
3(3) = 9
7(3) = 21
richard gets 9
andrew gets 21
3/5 = 0.6 = 60%
60% of the total take Spanish.
That leaves 40% for the other languages.
1/4 of 40% is 10% that take German.
40% - 10% = 30% take French.
Answer:
1.7 - 1.5 = 1.2
11.2 - 3.1 = 8.1
Step-by-step explanation:
Marty read 4 times as many pages as Nelson and Jennifer COMBINED. Marty read 1,860 pages.
In total, after dividing Marty's total by 4, Jennifer and Nelson both read a total of 465 pages.
After subtracting Nelson's 240, Jennifer is then found to have read 225 pages.
B would be the best viable option, as it clearly shows that 240+?x4=1,860, which it does.
Hope this helped. Khan Academy is a great resource for any learner. :)
