How can you determine the best method of solving a system of equations?
Elimination is best used when both equations are in standard form (Ax + By = C).
Elimination is also the best method to use if all of the variables have a coefficient other than 1.
Hope this helps
Answer:
All to 1 decimal place
3) a = 11.4
4) b = 11.2
5) c = 4.5
6) e = 6.4
7) f = 30.8
8) g = 67.9
Step-by-step explanation:
Step-by-step explanation:
3) cos(18) = a/12
12xcos(18) = a
a = 11.4
4) tan(25) = b/24
b = 24xtan(25)
b = 11.2
5) cos(51) = c/7.2
c = 7.2xcos(51)
c = 4.5
6) sin(28) = e/13.6
e = 13.6 x sin(28)
e = 6.4
7) cos(47) = 21/f
f = 21/cos(47)
f = 30.8
8) sin(33) = 37/g
g = 37/sin(37)
g = 67.9
All to 1 decimal place
What is 700 x 30 plz answer
Answer:
I'm not really sure but I think it's 2
Step-by-step explanation:
So here's what I did;
x³+3x-9=x - 1 +2x
x³+3x - x -2x = 9 - 1
x³= 8
x = ³√8
x = 2
I hope this helps
1.) Let the required number be x, then
0.0001x = 9.99
x = 9.99/0.0001 = $99,900 ≈ $100,000
2.) Online Bank, Credit Union, Traditional Bank
3.) Use a budget to determine how much you can save, then automate the savings by direct depositing that amount from each paycheck
4.) True
5.) Deposit into a CD earning 2% interest
