Nicole is making tuna salad for her office colleagues. it takes of a pound of canned tuna to make 5 portions of salad. she uses pounds of canned tuna for every 2 onions used. if nicole uses a total of 4 onions, then how many portions of salad does she make?

IF she use 1 pound of canned tuna for every 2 onions used, then:

2 onions= 1 pound of canned tuna

4 onions=2 pounds of canned tuna

1 pound of canned tuna = 5 portions

2 pounds of canned tuna = 10 portions

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
