The answer is 7
If you cancel 1 with -1 you will only have 3y=21 and 3 x 7 is 21 so y=7
Answer:
2x-12+5=3x-3
1. subtract 3x-2x
-12+5=x-3
2.-12 add to 5
-7=x-3
3. add three to seven
-4=x
Step-by-step explanation:
The answer would just be 50/1 or just 50
Answer:
r = 
Step-by-step explanation:
Given the proportional equation
y = rx ← r is the constant of proportion
Divide both sides by x
= r
Use any ordered pair from the table.
Using (8, 2 ) , then
r = 
=
Answer:
A. t(x) = 450 - 0.06x
Step-by-step explanation:
The layer which is originally 450 m thick is decreasing by 0.06 m.
450 - 0.06
... per day. x represents days.
0.06x
So,
450 - 0.06x
