Answer:
Step-by-step explanation:
Solve each inequality one at a time:
5x ≤ 21 + 2x and
3x ≤ 21 so
x ≤ 7
The other inequality is
3x + 3 ≥ 24 and
3x ≥ 21 so
x ≥ 7
If x is less than or equal to 7 AND greater than or equal to 7, then the solution is all real numbers.
Answer:
24 hours
Step-by-step explanation:
Kristen = 8 hours
Kristen and Courtney = 6 hours
Courtney = x hours
in six hours kirsten can do 6/8 of the job
6/8 = 3/4
So kirsten is going to be doing 3/4 of the job
Courtney is only going to do 1/4 of the job
Number of hours it takes Courtney to do the job
6/x = 1/4
Cross product
6 * 4 = x * 1
24 = x
x = 24 hours
It will take Courtney 24 hours to type a 50-page paper on her own
Answer:
T=71 degrees
Step-by-step explanation:
180- 82º-27º=71º
you got this! lmk if you need any more help! <33
We have an equation for the surface area of a rectangular prism:
A= 2 (w*l+ l*h+ h*w)
Plug l= 16 in, w= 12 in, and h= 5 in into the above equation, we have:
A= 2 (12 in*16 in+ 16 in* 5 in+ 5 in* 12 in)= 664 in^(2).
The final answer is 664 in^(2).
Hope this is helpful~
