What's each algebraic property of this problem?
7c + 0.20(140) = 49 < -- step 0
0.20 x 140 = 28 < -- step 1:
7c + 28 = 49 < -- step 2:
- 28 - 28
7c = 21 < -- step 3:

7 7
c = 3 < -- step 4:

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

x=0

step-by-step explanation:

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.

answer is  

a.

5.56

hope you get this right.
