All you have to do is combine 3x and 5x to = 8x. You can't combine 8x and 67y because they have different variables. so it's 8x+67y.
The answer is 12 edges :)
4miles ..............56 minutes
42miles .............x
x= (42*56)/4
x= 2352/4
x= 588
4(5x + 3) - 4x
4*5x = 20x
4 * 3 = 12
20x and 4x are like terms,so 20x - 4x=16x
12 doesn’t have anything to go with,so it just stays
16x + 12 (B is the correct answer)
The formula to find the amount is
The given function is
Comparing them we get
Subtracting 1 from both sides
Multiplying by 100 on both sides
