They will have the same solution because the first equation of system b
is obtained by adding the first equation of system a to 4 times the
second equation of system a.
Step-by-step explanation:
Linear pairs = 180°!!!!!
- 1st angle is 2[x]-39 2nd angle is just x
- soooo add the x. 3x-39=180
- 3x=141 x=47
X is just the second angle!!!!!
lol. i toonk geo last year and i cant believe i still remember all this hopefully i got it right!
To find out how many 3 course meals there are you will multiply all three numbers together. The reason for this is that you can group each item with each of the other options. This is a triple grouping.
4 x 4 x 5 = 80
There are 80 possible combinations.
1 + 3 + 5 + 7 + 9 = 25
25 ÷ 5 = 5
The answer is 5
