The maximum capacity for an elevator is 15 people and 3000 pounds. it is estimated that adults weight 200 pounds and children under 16 weight 100 pounds.
how would you describe this in systems of inequalities?

4.0 ft

step-by-step explanation:

4.0 ft

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
