Answer:

Step-by-step explanation:
Before adding we require the fractions to have a common denominator
The lowest common denominator of 2, 5 and 3 is 30, thus
+
+ 
=
+
+ 
Add the numerators leaving the denominator
=
= 
7/8 is the answer hope this helps
Answer:
it should be A if not I'm so so sry
Probability of an event =
(number of ways the event can happen) / (total number of possible outcomes) .
Well, the total number of possible outcomes is easy. It's
(6 possibilities for the first cube) x (6 possibilities for the 2nd cube)
= 36 total possible ways for two cubes to roll.
Now, how many of those possibilities show either 4 or 7 ?
Well, here's how a 4 can come up:
1 . . . 3
2 . . . 2
3 . . . 1
and here's how a 7 can come up:
1 . . . 6
2 . . . 5
3 . . . 4
4 . . . 3
5 . . . 2
6 . . . 1 .
So there are 9 ways all together for Lenny to be successful.
The probability is (9/36) .
That's 1/4 , or 25% .
Answer:
The answer is option A
Step-by-step explanation:
Reflection in the y axis is
(x , y) → ( - x , y)
The coordinates of A are ( 2, -5)
When it's reflected in the y axis it becomes
( - 2 , - 5)
Hope this helps you
