Solve for z in the literal equation 4/3 (z + 5) = y.
3

Z = 0.9y - 20

                           4

Step-by-step explanation: First, add (-20)/3 to both sides. Then, divide both sides by 4/3.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

answer: about 22.67
