Pls help me with questions 3,6 and if you can 8?

3. 12

6. 80%

8. y=-9

Step-by-step explanation:

Three:

Two dozen equals 24, since one dozen is 12. So what (lets say x) times 24 is equal to 60?

= 2.5

So you multiply $4.80 times 2.5. That equals 12!

Six:

So you take the number (80) and you find out what the simple percents are, so I like finding out what 1% of the number is. So what is 1% of 80? 0.8. How do you find that? You divide the number by 100! Now you need to find out what percent 64 is. So you just divide 64 by 0.8!

= 80. This says that 64 is 80% of 80!

Eight:

Eight is just plugging numbers in. You have what x equals already, so it just turns into a simple equation once you plug it in.

Just plug x in

Now just solve!

As we see,

Have a nice day and don't forget to mark brainliest!

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

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
