Answer: 21
Step-by-step explanation:

Substitute the value of z into the expression:

Express the line in slope intercept form
this is done by making y the subject.
y = 3x/2 + 4
slope is 3/2
product of perpendicular lines is negative one
let me slope of the other line
m * 3/2 = - 1
m = - 2/3
Answer:
83.2 miles
Step-by-step explanation:
what i had to do was multiply 7.3 by 13 and that was 94.9 that was as close as i could get it to 100 so i then multipled 6.4 by 13 and got 83,2 miles
Let number of plastic containers collected by fourth grade= x
Then number of plastic containers collected by fifth grade students=x-216
OR
If number of plastic container collected by fifth grade is y
then number of plastic container collected by fourth grade=y+216
So, we can write it as follows
⇒ number of plastic containers collected by fourth grade= number of plastic containers collected by fifth grade +216
