The variables y and x have a proportional relationship, and y = 28 when x = 21. What is the value of x when y = 42?
0 x = 14
o x = 18
o x = 31
OX = 56

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

42.4 6th grade students prefer hip hop

step-by-step explanation:

40 percent of 106 = 42.4

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
