Answer:
6in
Step-by-step explanation:
Using the pythagerous thereom,
10^2 = 8^2 + b^2
b^2 = 10^2-8^2
b^2 = 100-64
b^2 = 36
b = 6

Answer:
uiu7n
Step-by-step explanation:
Let the number of chemistry books be x and the number of calculus books be y
total number of books in each case is:
x+y=24
x=24-y.....i
Weight of each case:
2707.2/20
=135.36
thus
4.2x+6.0y=135.36..ii substituting i in ii
4.2(24-y)+6y=135.36
100.8-4.2y+6y=135.36
hence
1.8y=34.56
y=19.2
hence
x=24-19.2
x=4.8
thus the number of chemistry books was 4.8*20=96 number of calculus was
19.2*20
=384 books
x=0
let's solve your equation step-by-step
2(4x+3)-12=3x-6
(8x)+(6-12)=3x-6
8x-6=3x-6
subtract 3x from both sides.
8x-6-3x=3x-6-3x
5x-6+6=-6+6
5x=0
5x/5=0/5
x=0
I hope that helps you
