Please help on number 26

38 percent. 24 divided by 64 classmates is 0.375 which is also 37.5 percent. You can either round up which would make it 38 or keep it at 37.

One number is 7 more than another. The difference between their squares is 161. What are the numbers?

olga nikolaevna [1]

Let's say the numbers are "a" and "b"

now, we know one of them is 7 more than the other, so hmmm let's say "b" is 7 more than "a", so b = a + 7

the difference of their squares is 161, alrite

$\bf a^2-b^2=161\qquad b=a+7\implies a^2-(a+7)^2=161
\\\\\\
a^2-(a^2+14a+49)=161\implies \underline{a^2-a^2}-14a-49=161
\\\\\\
-14a-49=161\implies -49-161=14a\implies -210=14a
\\\\\\
\cfrac{-210}{14}=a$

and surey you know how much that is

now, what's "b"? well, b = a + 7
