X+y=15
2x+3y=37
15-x=y
2x+3(15-x)=37
2x+(45-3x)=37
2x-3x+45=37
-1x=-8
x=8
x is the amount of bikes, so there are 8 bikes. 8x2=16.
37-16=21
21/3=7
There are 7 tricycles.
18x^3 +9x / 6x^2 = 3x
18x^3
--------
0 9x
so than (18x^3 +9x) divided by 6x^2 will be equal 3x and the remainder is 9x

Answer:
200 minutes
Step-by-step explanation:
Given that:
Cellular - Tastic (f) :
Monthly fee = $35
Per minute fee = $0.11
Dirt cheap call (g) :
Monthly fee = $55
Per minute fee = $0.01
How many minutes would you need to use for the cell phones to cost the same
amount?
Let number of minutes for cost to be equal = x
35 + 0.11x = 55 + 0.01x
Collect like terms
0.11x - 0.01x = 55 - 35
0.1x = 20
x = 20/0.1
x = 200
Hence, for cost to be the Same, 200 minutes must be used
Answer:
Yes, because 3/4 is bigger then 1/2 so there is more then 1 in there. The expression 1/2 divided by 3/4 is smaller then 1 because 3/4 is already bigger so you can't fit one in. Without using fractions it is like 3/2 is bigger then 1 since 2 is smaller then 3. 2 divided by 3 is less because 3 is bigger so you can't fit the 3 in a 2.
