Answer:

Step-by-step explanation:

We have to get

from the number that goes IN

to the number that goes OUT

using addition and subtraction.

Note:

To get from a small number to a big number will use addition and

to get from a big number to a small number will use subtraction.

from IN: 11 to OUT: 26

11 + ? = 26

Compare the two numbers by making the difference 26 - 11= 15

11 + 15 = 26

Rule: Add 15

See picture for the rest of the rules.

The company installs 5000 light bulbs with an average of 500 hours for each bulb. The standard deviation of 100 hours and distribution approximated by a normal curve. The percentage of bulbs that can be expected to last the period of time of less than 690 hours is 97.1%. This will make the answer to be C.

Part A: Solve −np − 70 < 40 for n. Show your work. (4 points) Part B: Solve 4w − 7k = 28 for k. Show your work. (6 points

likoan [24]

For part A, lets write the problem

$-np - 70\ \textless \ 40$

add $70$ to both sides

$-np - 70 + 70 \ \textless \ 40 + 70

-np \ \textless \ 110$

we are going to reverse the inequality, to do this we are going to multiply both sides by $-1$

$(-np ) ( -1 ) \ \textgreater \ 110 ( -1 )$

$pn \ \textgreater \ -110$

divide both sides by $p$

$\frac{pn}{p} \ \textgreater \ \frac{-110}{p}$

our answer would be

$n \ \textgreater \ \frac{-110}{p}$

lets go with part b, lets write the problem

$4w - 7k = 28$

subtract $4w$ from both sides

$4w - 7k - 4w = 28 - 4w$

$-7k = 28 - 4w$

divide both sides by $-7$

$\frac{-7k}{-7} = \frac{28}{-7} - \frac{4w}{-7}$

I few simplified it, we would be left with,

$k = -\frac{28 - 4w }{7}$

I hope this helped!!
