None maggie is over the amount
All are correct except the last one. You have the numbers turned around.
She has 176 plants, but she needs 180.
oh okay so I jus need to subtract correct?
20*9=180
189-176=4
right?
Right.
Thank you. If you don't mind can you look over some more problems if available? I just want to ensure that I am doing the problems correctly
Sure. I'll check all of the problems that I can.
Thanks Ms. Sue
Perform the computation.
(-20) - (-1)
A) -19
B) -21
C) 21
D) 19
=-19
Compute the value:
|– 6 – 4|
=-10
Evaluate:
(–9)( –7)( –5)( –2)
A) 630
B) -630
C) -621
D) 621
(-63)(-10)=-630

6 trucks needed
Write the decimal as a fraction in lowest terms.
0.014
14/1000=7/500
Compute the difference. Express the answer in simplest form
7/9-3/4
common denominator is 36(9*4)
I then multiplied the numerator (7*4=28)(3*9=27)
28/36-27/36=1/36
Perform the indicated operation. Express your answer as a whole or mixed number or as a fraction in simplest form
14 4/7 + 2 5/7 +20 1/7
Since the demoninators are the same I added straight across
14+2+20=36
4+5+1=10 and the denominator is 7 which equals to 36 10/7 which is an improper fraction. so i multiplied 36*7+2 =262/7. 262 divided by 7 is 37 3/7
Divide. Express your answer in simplest form.
2 4/7 divided by 9
I treated the problem as a improper fraction so I multiplied 7*2+4=18
7*9=63...so my fraction now is 18/63=2/7
Solve the proportion:
p/17.5=4/10
A) 3.5
B) 8
C) 7
D) 14
17.5/10=1.75
1.75x4=7
x=7
Thank you so much for helping to assiting me Ms. Sue. I think I got all of the problems pretty much correct. I just wanted my answer to be double check.
Congratulations. All are correct!
I cant thank you enough, Ms. Sue! I hope you have a wonderful evening
You're very welcome, Tasha. You have a great evening, too.
Actually this one is incorrect.
Compute the value:
|– 6 – 4|
=-10
The answer is 10. The lines are absolute value signs which means you can never have a negative answer (unless there is a negative sign outside of the absolute value lines.
