Suppose a crew member at an unloading dock can unload 3 trucks per hour and have already unloaded 17 trucks. which equation can be used to medel the number of trucks the crew unloads after h hours?
a. 3h+17
b. 3h=17
c. 17h-3
d. 17h+3

A. 3h+17

Step-by-step explanation:

Given,

The initial number of unloaded trucks = 17,

Also, 3 trucks per hour can be uploaded,

So, the additional number of uploaded truck after h hours = 3h,

Hence, the total number of uploaded trucks after h hours = Initial uploaded trucks + additional trucks

= 17 + 3h

Which is the required equation,

Option A is correct.

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
