Answer:
a) Let her comic books be x
b) as she sold half it will be
+ 8 = 13 ( as she sold half and then she bought 8 more that means plus and then now she have 13 that means = 13)
c ) to solve to find the books she have we need to
+ 8 = 13
Transpose
= 13 - 8
= 5
x = 5 × 2
x = 10
the comic books were 10
we can even cross- check to see if the value is right instead of x put 10
+ 8 = 13
5 +8 = 13
13 = 13
Cross-checked
Answer:
To use the elimination method one coefficient of either x or y must be the same number with opposite signs, so the ordered pair is (-10, -8)
Step-by-step explanation:
2(-x+y=2) Make one of the coefficients equal, with opposite signs.
2x-3y=4 Combine equations.
-y=8 Solve, y=-8
Then find x, -x-8=2
-x=10, so x= -10
(-10, -8) is your answer.
Answer:
A. The Number of Lost games = 154 Games
B. Number of games won is greater than the number of games lost.
Step-by-step explanation:
A. how many games did they lose in both years?
Total Number of games = 104 tournaments x 3 Games in each tournament
Total Number of games = 312 Games
The No. of Lost games= Total Games in 2 years - Games won in 1st year - Games won in 2nd year
The No. of Lost games = 312 - 55 - 103
The No. of Lost games = 154 Games
B. Is the number of games won greater than the number of games lost?
Total Number of Games won = 158 Games
Total Number of Games lost = 154 Games
Hence, Total Number of Games won is greater than the Total Number of Games lost.
