Answer:
You can't answer this question without knowing the total amount of money they all had in total.
Answer:
So in order to find the missing number, we must find the difference with the numbers that we were given.
Problem #1
42-30= 12 and 84-69= 15. It's possible that each difference increases by one Let's see...
30+12= 42
42+13= 55
55+14 = 69
69+15 = 84
So for 1., all you have to do is keep adding the difference and increase it by 1 each time. If you wanted to keep increasing, you would add 84+16, then 100+17, etc.
Problem #2: As for the second one, I had trouble solving it, sorry :(.
Problem #3
3. For the third problem, 27-22= 5 and 9-1=8. It looks like each difference increased by 1.
27-22 = 5
22-6 = 16
16-7 = 9
9-8= 1
The value of 6 in 465.09 divided by 100 is 0.6 which is 6 tenths.
Tod do this, you need to move the 6 twice to the right so its place value will change and divide by 100.
Answer:
a =5
Step-by-step explanation:
-26a-3+20a=27
Combine like terms
-6a -3 = 27
Add 3 to each side
-6a -3+3 =27+3
-6a = 30
Divide each side by -6
-6a/-6 = 30/-6
a =5
45% of 450 is 202.50
$202.50 is the price of markup
$652.50 is the selling price
