Hell me pls find x

5.6

Step-by-step explanation:

If the pentagons are similar then the following side lengths must be proportional

5 with 7 and x with 4

7/5 = x/4 cross multiply expressions

28 = 5x divide both sides by 5

5.6 = x

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.
