let's say is "x", therefore "x" is the 100%, and we know that 0.35 is the 4%.

First distribute
a(b+c)=ab+ac
y(x+z)=yx+yz
3z(x+y)=3zx+3zy
so now we have
yx+yz=3zx+3zy
make all x's on one side
subtract 3zy frm btohs ides
yx-3zx+yz=3zy
subtract yz frmo both sides
yx-3zx=3zy-yz
undistribute the x on the left side
x(y-3z)=2zy
divide both sides by (y-3z)
x=
Answer:
Step-by-step explanation:
192 ÷ 420 = 0.457
0.457 x 100 = 45.7
But there can't be a percentage increase or decrease because there is no percentage to compare it to, there should be information for the change in students of the last year
Ok so first just pay attention to the Mystery books and Science books.
there are 13 mystery books and 15 Science books so your answer will be two.
Hope this helps.
