Question

can someone help me with algebra? please? i really need help?

Answer 1

What's the question? (:

Answer 2

this is the question - - > In a certain town, the barometric inches of air pressure, x, on a certain day is described by two statements:

If 3 times the air pressure is increased by 2, the pressure is still less than 92 inches.
Twice the air pressure minus 39 is greater than 11 inches.

I already have Part A, i just need help with part B and C

Part A: Part A: Create a compound inequality to represent the air pressure range (My answer: 3x+2<92 and 2x-39>11

Part B: Can the air pressure in this town be 24 inches? Justify your answer by solving the inequalities in Part A.

Part C: The average air pressure in another town is 29 inches but the actual pressure is within 4 inches of the average. Write and solve an inequality to find the range of air pressure in this town. @helppls123

Answer 3

okay so i'm thinking for part B you should plug in 24 for x and see if the problem is still true, and I don't really understand part C sorry >_<

Answer 4

You can solve an inequality just like an equation, except if you divide by a negative number you have to flip the sign around for reasons I am bad at explaining.

But if you want to write it in terms of x you can just do
\[2x - 39 > 11 \\ 2x > 50 \\ x > 25\]
Which means 24 is not a good answer.

Answer 5

i don't get this :/ so what do i put for part B and C?

Answer 6

I was showing you what to do for part B. :D

Answer 7

okay so can i put what you put for part B? and now that i have part B what can i do for part C?

Answer 8

Well, ideally, you'd look at it and understand it instead of just copying what I did so you can solve the next problem yourself. :P

Part C is basically like part A I think.

Answer 9

thats the part im confused on, how can i solve part C? i dont get it.

Answer 10

Can you write the inequalities?
