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!

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
