Answer:
a = kb
Step-by-step explanation:
"a is directly proportional to b" is expressed as a = kb, where k is the "constant of proportionality."
(Put what the first number is) x (the previous number) + 8 + 12 = ?
To find X, we can divide 5 into 40.
40 divided by 5 is 8.
Now we can do 5 x 8. That is 40.
X=40
OR we can do it another way.
40 divided by 5 is 8.
Cross out 5 divided by 5.
Now we have 8. Still.
X is 8
