2. If 6x - 3y = 4 and 5x – 2y = - 7, what does x - y equal? A, 11
B-2
C. 71/3
D. - 23/3
E. NOTA

15.36 per mile

but forgot to round

i am pretty sure

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.
