(50) * (-4) =

2 negatives can be converted to a plus sign. -(-x) can be +x or just x.

-54--23

-54+23

23-54=-31

78--4

78+4=82

-48/-6

Now let's pause fer a sec. When a negative is being divided by another negative, the quotient(answer to division problem) becomes a positive.

-48/-6=8

50*-4=-200

Step-by-step explanation:

I have checked and verified these

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.
