Question

In a certain town the temperature, x in degrees Celsius on a certain day is described by two statements:


If 3 times the temperature is increased by 2, the temperature is still less than 14°C.
Twice the temperature minus 7 is greater than -11°C.


Part A: Create a compound inequality to represent the temperature range. (3 points)

Part B: Can the temperature in this town be 5°C? Justify your answer by solving the inequalities in Part A. (3 points)

Part C: The average temperature in another town is 3°C, but the actual temperature is within 4°C of the average. Write and solve an ine

Answer 3

3x+2<14
2x-7>-11
can you proceed further?

Answer 4

@surjithayer im not good at math at all, i just need it all done by today because if i dont i fail

Answer 5

3x+2< 14
subtract 2 from each
3x+2-2<14-2
3x<12
divide by 3
x<4
again
2x-7>-11
adding 7 to both sides
2 x-7+7 >-11+7
2x >-4
x>-2
or -2<x<4

Answer 6

thats the answers for A,B,and C

Answer 7

for A the equations
for B you can conclude from my final answer.

Answer 8

let x be the temperature ,then
3-4<x<3+4
-1<x<7

Answer 9

i dont understand
