1st question : 16,22. 14,20. 12,18
$8.16 is the unit rate per hour so just multiply the amount she makes per hour by hours. so there were 8 whole hours. $8.16*8=$65.28. then you have half an hour so $8.16/2=4.08. add. ANSWER: $69.36
SOLUTION:
x + x + 1 = 132 / 32
2x + 1 = 33 / 8
2x = 33 / 8 - 1
2x = 25 / 8
x = 25 / 8 / 2
x = 25 / 16
The first number is 25 / 16. Therefore, as the second number is consecutive we simply add 1 to the first number to achieve the second number as displayed below:
Second number:
= x + 1
= 25 / 16 + 1
= 36 / 16
= 9 / 4
ANSWER:
Therefore, the first number is 25 / 16 and the second number is 9 / 4.
Hope this helps! :)
Well lets look here at something.
Tenths are the greatest compared to hundredths or thousandths.
So if that is the case We can tell that 3.008 is the least since it only has one value on the end in the thousandths place (all are 3.??? which is why this stays true)
Tenths place > 0.000 (The First 0)
Hundredths place > 0.000 (Second 0)
Thousandths place > 0.000 (Third 0)
Look for the greater values in all of these. Remember tenths is greater than hundredths and hundredths to thousandths.
So we can order it properly > 3.825, 3.18, 3.09, 3.008

18. -500 + 250 = -250
19. -550 - 300 = - 850
20. 116 - (-50) = 116 + 50 = 166
21. 2500 + 1800 - 2200 = 2100
