Answer:
4.75x=54+2.5x x=24
Step-by-step explanation:
x=Number of games
4.75x=54+2.5x
Subtract 2.5x from both sides:
2.25x=54
Divide both sides by 2.25:
x=24
Answer:
To solve this we need to form 2 equations with only 2 variables.
x+4y-5z=-7
2x+y+5z=8
3x+5y=1
15x+10y+15z=35
6x+3y+15z=24
9x+7y=11
Now we need to use these to find x and y
9x+15y=3
9x+7y=11
8y=-8
y=-1
Therefore:
x=2
From this we can find that:
2(2)-1+5z=8
Therefore z=1
The answer is x=2, y=-1, z=1
Answer:
Step-by-step explanation:
cos O = adjacent / hypotenuse
cos O = 12/13
I hope I helped you^_^
6x^3+13x^2+16 is the result.
Answer:
x = 3
Step-by-step explanation:
Subtract 8x from both sides.
3x+4−8x=8x−11−8x
−5x+4=−11
Subtract 4 from both sides.
−5x+4−4=−11−4
−5x=−15
Divide both sides by -5.
−5x
−5
=
−15
−5
x=3
