Answer:
x = 20/9
Step-by-step explanation:
We want to write out all of the mixed fractions into improper fraction form. So -2 and 1/9 becomes -19/9 and -4 and 1/3 becomes -13/3. Then we get (-19/9) - (-13/3). The two minus signs together means a positive/plus sign, so we get -19/9 + 13/3. In order to add, we want the denominator to be the same. A common denominator could be 9, so -19/9 + 13(3)/3(3) = -19/9 + 39/9 = 20/9, which is our final answer
Answer:38 t-shirts
Step-by-step explanation:
P=30t-640 main street
p=25t-450 broad street
30t-640=25t-450

5t-640+640=-450+640
5t/5=190/5
t=38

Ok, so I'll make an example problem to show.
There's a forest in town and it's recorded that there are 5 bears and 100 squirrels in it.
First, you would make this a ratio so that would be 5:100. 5 being the bears and 100 being the squirrels.
To simplify it, just make it into a fraction. The first number, going from left to right, would be the numerator and 100 would be the denominator.
5
-----
100
To simplify, just divide by the greatest common factor which would be 5 in this case.
5 1
----- / 5 = ----
100 20
