Given the numbers, let’s set up an equation:
2 + 6 + n = 15
We can solve this using steps:
1. Simplify
8 + n = 15
2. Subtract 8 from both sides
(8 - 8) + n = 15 - 8
3. Simplify
n = 7
Let’s plug in 7 to see if it makes sense:
2 + 6 + 7 = 15
Because this equation is true, we have found our number.
Our unknown number is 7.
If he makes it 80% of the time that means he makes it .80 of the time (I just made it a decimal)
After 1 shot his probability is .80
After 2 shots his probability is .80X.80 = .64 or 64%
2^1 because when you times indices you add the indices and when you divide you subtract it
$77 since 110 x 0.3 = 33. Then minus this value from 110, then the answer is $77
Answer:
1 = x and -2 = y
I am fairly happy with this answer
