They sell tacos for $3.25 each which would be $3.25x....and they make an expense of $210 a day so your equation would be... $3.25x = $210 in which you would divide 210 by 3.25 to get your answer on how many tacos they would have to sell per day to make that expense....
I don't know what you mean by benchmark but this is adding fractions. when you add fractions you must have the same denominator. 10 and 5 are not the same so you need to find the same denominators conveniently 2/5 is equivalent to 4/10 (by multiplying the fraction by 2) then you add the numerator straight across keeping the same denominator. that would be 5/10. Simplify to the is 1/2
From the information, w=k/√v
where k is the constant of proportionality, given by:
k=w√v
w=3 when v=6
thus
k=3√6
hence:
w=(3√6)/√v
hence the value of w when v=3 will be:
w=(3√6)/√3
w~4.24264
All real numbers. the domain is all numbers grater than zero
Another name for 1/4 is a quarter
hope this helps
