What does -B + a = 8 mean

Step-by-step explanation:

If you're looking to find what b= Subtract a from both sides

-b=-a-8

Then divide negative 1 from both sides to equal

b=a+8

If you're looking to find what a= Add b to both sides

a=b+8

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.
