Answer:
Value of stamp collection = (45b + 43) cents
Step-by-step explanation:
What we have here is as follows;
if there are x 3-cent stamps, then there are 4x 10-cent stamps
So the number of 2-cent stamps is 1 less than 3 cent stamps and that will be x-1 2 cent stamps
Number of 2 cents stamps = b
This means that x-1 = b
Thus, x = b + 1
So the value of the stamp collection is as follows;
x 3 cents stamps = 3(b+ 1) = 3b + 3 cents
4x 10 cents stamps = 10(4(b + 1)) = 10(4b + 4) = 40b + 40
value of the 2 cents stamp = 2b cents
Total value is thus;
2b + 40b + 40 + 3b + 3 = (45b + 43) cents
I TOLD U THE ANSWER CHECK
Answer:
x =
- 4y + 12
Step-by-step explanation:
y = 2 + 
Put the 2 on the other side
y - 2 = 
Square both sides
= x - 8
Expand the brackets
- 4y + 4 = x-8
Move 8 to the other side
x =
- 4y + 12
Answer:
