The answer is 31/40
because first you got cane both of the fraction to the same denominator.
72/80 + 70/80
Add 72+70=142.
142/80 change it to an mixed number and it will be 1 31/40 in simplest form.
Answer:
(x + 5)^2 = (5 - 3)^2
Step-by-step explanation:
Given the equation;
x^2 + 10x + 22 = 13
We have;
x^2 + 10x = 13 - 22
x^2 + 10x = -9
Adding half of 10 to both sides and completing the square as usual, we have;
(x + 5)^2 = 5^2 + (-9)
(x + 5)^2 = (5 - 3)^2
Speed = distance / time
Tuesday: speed = 2.4km / 18 minutes = 0.13 km per minute
Friday: speed = 1.8 km / 12 minutes = 0.15 km per minute
0.15 is larger than 0.13 so she ran faster on Friday.
It’s 80,610 if you really mean the tens place.
If you mean the one tenths place then it’s 80,607.2
