shawn wants to use an elevator to carry identical packages having the same weight. each package weighs 5 pounds and shawn weighs 100 pounds. if the elevator can carry a maximum of 340 pounds at a time, which inequality shows the maximum number of packages, n, that shawn can carry with himself in the elevator if he is the only passenger

Step-by-step explanation:

Let n be the maximum number of packages, that Shawn can carry with himself in the elevator if he is the only passenger.

Since each package weighs 5 pounds and Shawn weighs 100 pounds.

Total weight = Shawn's weight + (Weight of each package ) x (Number of packages)

= 100+5n

Since , the elevator can carry a maximum of 340 pounds at a time , then

Subtract 100 from both sides , we get

Divide both sides by 5 , we get

So , the inequality shows the maximum number of packages, n, that Shawn can carry with himself in the elevator if he is the only passenger is .

x= 3^y

step-by-step explanation:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
