an =a1+d(n-1)
where d is the common difference
d=5-8
d=-3
a1=8
an =8-3(n-1)
Choice C
Answer:
27 13/60
Step-by-step explanation:
What you have tried to do is not an impossible way to do it. What you could do is set your fractions and whole numbers like this.
( 7 + 1/10) * (3 + 5/6) I don't know if you know what FOIL is, but that is the way to proceed.
- First: (meaning the first in each factor ). 3 * 7 = 21
- Outside: (meaning the two terms near outside the brackets) 7 * 5/6 = 5 5/6
- Inside: The two terms closest to the * sign 1 / 10 *3 = 3/10
- Last: The two end terms (1/10 * 5/6 = 5/60 5/60
Now you can add. 21 + 5 is the whole number amount = 26
Add the fractions
- 5/6 + 3/10 + 5/60 The lowest common multiple is 60
- 50/60 + 18/60 +5/60 = 73 / 60 = 1 and 13/60
Add that to 26 and you get 27 13/60
Answer:37.5 hrs
Step-by-step explanation:
15/4 = 3.75
3.75*10=37.5
You are going to times 25.50 together and that's 51 so then you are going to divide 51.00 by 4.25 and that's 12
So the answer is 12
