So assumn that the measures given are the legnths of the sides
perimiter=side1+side2+side3
so
side1=4 and 1/2
side2=5 and 1/2
side3=6
subsitute
p=(4+1/2)+(5+1/2)+(6)
associative prpoerty says (a+b)+c=a+(b+c) (it deals with addiont with parenthasees)
p=4+1/2+5+1/2+6
p=4+5+1/2+1/2+6
p=9+1+6
p=10+6
p=16 inches
Answer:
822 hours
Step-by-step explanation:
Let's say that you work for h hours. Then since each hour, you charge $10.25, then your total earnings after h hours will be:
10.25 + 10.25 + 10.25 + ... + 10.25, where you add 10.25 to itself h times.
Adding a number n to itself x times is the same as multiplying that number n by x: nx. It's the same thing here: we multiply 10.25 by h because we added 10.25 to itself h times:
10.25 * h
Now, we do know that the actual total amount of money you earn is $8425, so we can just set this value equal to our above expression:
10.25 * h = 8425
Divide both sides by 10.25 to solve for h:
h = 8425/10.25 ≈ 821.95 ≈ 822 hours
Hope this helps!
9- 0.9 or .9 either of these would work
6/30- 6.30
Expand:
25(-3.6-x)=5
25(-3.6)+25(-x)=5
-90-25x=5
-25x=95
X=-95/25
X=-3.8
