Answer:$440
Step-by-step explanation:
Principal(p)=$200
Rate(r)=12%
Time(t)=10years
Simple interest=(pxrxt) ➗ 100
Simple interest =(200x12x10) ➗ 100
Simple interest=24000 ➗ 100
Simple interest=240
Total amount=p + simple interest
Total amount =200+240
Total amount =440
They are all like-terms so you can add 7y+3y which equals 10y. Then subtract 10y-17y and you get a negative number; -7y
Step-by-step explanation:
Eliminate the x:

Eliminate the y:

Well, if the product has two decimal places and it is known that one factor has none, then the other factor must have two decimal places. Where would those two decimal places in the product come from otherwise?
Some examples:
1 * 34.44 = 34.44
2 * 17.22 = 34.44
In both cases, the non-integer factor had two decimal places.
