1. Since it's m - 7 you would have 7 to both sides so you would in fact have m < 13. If you double check your answer, you see that if m is say 12 (because 12 is obviously less than 13), 12 - 7 < 6

2. Again, use the same process on this problem as the first one. Add 8 to each sides because it's you're subtracting 8 from n. So you end up with n > 13. Check your answer. Say n is 14. 14 - 8 > 5

3. This one is different because you are adding 5 to p. So in order to get p by itself, you need to subtract 5 from both sides. p < 5. Say p is 4, 4 + 5 < 10.

When working with problems like these, you need to isolate the variable on one side and get it by itself.

The mean of three number is 15. if 2 of the numbers are 18 and 16 what is the third number​
MrMuchimi

Answer:

11

Step-by-step explanation:

The mean is calculated as

mean = \frac{sum}{count}

let the third number be x , then

\frac{18+16+x}{3} = 15 ( multiply both sides by 3 to clear the fraction )

34 + x = 45 ( subtract 34 from both sides )

x = 11 ← third number

Can someone help will mark brainlist
Marina86 [1]

Answer:

See below

Step-by-step explanation:

the common ratio, r <1    so it CONVERGES    (r = 1/2 in this series)

sum = a1 ( 1-r^n) / (1-r) =  1000(1-.5^10)/(1-1/2) = ~1998

    for n= 30    this results in ~~2000

As it continues, the terms get smaller and smaller and the SUM converges on 2000.
