Answer:
50%
Step-by-step explanation:
if there are 2 sets of 7 marbles each part is worth 50% (them put together is 100%). Therefore you have a 50% chance of getting a red marble
It's close to six and it's shorter so 5?
Answer:
first option, x < 7
Step-by-step explanation:
- Since the circle is not filled in at 7, that means it doesn't equal 7
hence options 2 and 4 are NOT correct
- Since the arrow is going to the left of 7, all smaller numbers (ex. 6 or 5)
x is less than 7
the third option is incorrect because x is not bigger than 7
Step-by-step explanation:
For a geometric sequence,

1. The sequence is :
3, 13, 23, 33,...

It is not geometric. It is false
2. The sequence is :
5, -25, 125, -625

So, the sequence is geometric as the common ratio is same. It is true.
Answer:
x = 
Step-by-step explanation:
Given
5xy + a = c ( isolate 5xy by subtracting a from both sides )
5xy = c - a ( isolate x by dividing both sides by 5y )
x =
