Answer:
60 cups
Step-by-step explanation:
<u>0.8 / 9.2 = x + 0.2</u>
Perform the division on the left side: 0.08696 = x + 0.2
Subtract 0.2 from each side: <em>-0.113 = x</em> (rounded)
Y=4.
find x=-3 the look up and down vertically to x=-3 then find the corresponding y is.
1st one: only mentions 1 p wrong
2nd one: saving means (-) cost so this is also wrong
3rd one: how much you owe is x-y and there is no (-) sign in there so it is wrong
the answer is the 4th one because it has p+14%p if p=price and 14%p=14% of p tax
To add fractions you want to make sure that the bottom numbers are the same so we have to make them the same, but we have to make sure that the fractions are unchanged so we get the correct answer
so if we find out what number that 9,7, and 5 can all multiply into. we find that 9 times 7 times 5 or 315 is the number that will work
so to get them to all be over 315, we must multiply each fraction by a form of 1/1 or x/x or (number)/(same numbe as on top)
so 7/9 times (35/35)=245/315
1/7 times (45/45)=45/315
3/5 times (56/56)=168/315
we add them togther
245/315+45/315+168/315=(245+45+168)/315=458/315
this simplifies to 1 and 143/315
