Multiply 20/5 by nine so 20/5 simplify into 4 4 times nine is 36, so only 36 kids liked the book
M=2
The slope intercept form is y=Mx+b,where m is the slope and b is the y intercept y=Mx+b
Using the slope intercept form the slope is 2 m=2
All lines that are parallel to y =2x-5 have the same slope of 2
M=2
Set up a proportion. 6/10 = 9/x. cross multiply so x times 6 = 6x. And 10 times 9 = 90. so 6x=90. Then 90 and 6x divided by 6. which gets you x=15. The 9 ft tall elephant will cast a 15 ft shadow.
