-6k-6 = -8k+22
-6k+8k = 22+6
2k = 28
K= 28/2
K= 14
Step-by-step explanation:
these look easy you can probably just type it into a calculator, just show your work.
not sure where you got 20 from on the first problem it should be 9/12 I think, based on the examples at the top of the page.
1. 9/12
2. 16/22
3. 30/36
4. 28/44
5. 45/55
6. 50/60
The "/" indicates division btw and or fraction
then do the #x#x#x#x# thing you were doing
Answer:
7) 3m + 21
8) 8t + 12
9) 45 + 30r
10) 32n - 16n or just 16n
Step-by-step explanation:
just use the distributive property

Answer:
30
Step-by-step explanation:
Substitute the x in the expression with a -5 and substitute the y in the expression with a 6
2(-5)+8(6)
-10+40
30
Given:
Mean, μ = 196
Std. dev., σ = 22
A sample size of 50 (> 30) is large enough to provide meaningful data.
The random variable is x = 200.
The z-score is
z = (x - μ)/σ = (200 - 196)/22 = 0.1818
From normal distribution tables, obtain
Prob(X < 200) = 0.572 = 57.2%
Answer: 57.2%
