4 0

Step-by-step explanation:

A and E

A

because x+5 = x-5

x-x = -5 -5

0 = -10

E

8 + 4f = 4(3+f)

8 + 4f = 12 + 4f

4f - 4f = 12 - 8

0 = 4

Chisaka has less than 145kg of food remaining in her spaceship. She needs a constant amount of food each day that she spacewalks
Veseljchak [2.6K]
If Chisaka does not space walks, the days she spend spacewalking are equal to zero. Since <span>S represents the number of days Chisaka spacewalks, we just need to replace </span>S=0 in our inequality to find how long her food will last if she does not spacewalks:
2.22S+1.3N\ \textless \ 145
2.22(0)+1.3N\ \textless \ 145
1.3N\ \textless \ 145

From this calculation we can infer that the coefficient of N, 1.3, is the amount of food she needs per day if she doesn't spacewalks. Similarly the coefficient of S, 2.2, is the amount of food she need per day if she spacewalks.

We can conclude that Chisaka will need 1.3 kg of food if she doesn't spacewalks, and 2.2 kg of food if she spacewalks.
