Answer:
Step-by-step explanation:
So it's basically an extra special complicated addition problem. Let's take it step by step.
We'll call the books book A, B and C. Well we know Book A has 120 more pages than book B, so if we say book B has x pages, then book A has x +120 pages.
Then we know that x is 75 less than the third, so we can say book C has x + 75 pages. So in order the number of pages each book has are
A = x + 120
B = x
C = x + 75
We also know A + B + C = 1005. Can you handle it from there? Or is there anything you don't understand?
Answer:
x=15
Step-by-step explanation:
If x is 3 and y is 21, then that means that y is 7 times the value of x (21/3=7), or y=7x.
If y is 105, then 105=7x
105=7x
105/7=x
15=x
Answer:825000
Step-by-step explanation:
Answer: it would be 12.
Step-by-step explanation:
you'd use the pythagorean theorem.
a^2+b^2=c^2
a is the first leg, b is the second leg, and c is the third leg.
10^2+13^2=c^2
100+169=c^2
269=c^2
take the square root of both sides
16.4=c
16.4cm is your answer!
