Answer:
-5.25 + 3.5 = -1.75
Step-by-step explanation:
This can technically be done two ways. The first is the most simplified, and the second less simplified, and less likely to get the best grade.
1.So long as you don't have to order it chronologically, you should be good with this one: 
2.This one IS chronological (she got a correct answer, then a wrong answer), but you can NOT simplify it, because it asks for an addition equation: 
The best option is probably #1
Answer:
One Solution
Step-by-step explanation:
We can figure out the steps for this equation by separating the variables in the left side and the whole numbers on the right side, what you can essentially do is separate them and the equation will look like
12n = -9 + 6 -311
then,
12n = -314
which gives you, approximately
x = -26.16667.

400 ÷ 77 x 100 + 2000 - 55 + 999
u would use dmas :
1. division
2. multiplication
3. addition
4. subtraction
400 ÷ 77 = 5.19
5.19 x 100 + 2000 - 55 + 999
5.19 x 100 = 519
519 + 2000 - 55 + 999
519 + 2000 + 999 = 3518
3518 -55 = 3463
hope this helps
Answer:
Step-by-step explanation:
You can use the sin function,
cos x= adj/hyp
cos x= 14.3/19=0.752
x=arcos 0.752= 41.18 degrees
