ASAP PLEASE—-Mackenzie placed 5 pieces in the puzzle for bc every 4 pieces her little brother placed. If Mackenzie’s little brother placed 20 pieces in the puzzle, how many pieces did the puzzle have altogether

45 pieces.

Step-by-step explanation:

First, if the ratio is 5 : 4, then is you multiply 4 x 5 to get 20, you need to multiply 5 x 5 to get 25.

Second, 20 + 25 = 45 which is the total amount of puzzle pieces.

Hope this helps!

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
