Answer:
x= 7
Step-by-step explanation:
add (12x+1) and (5x-3) which becomes 17x-2 and then set that equal to 117 and solve. move the 2 to the right side of the equation which becomes 17x=119 and then divide 119 by 17 which x equals 7.
plug in 7 for x to make sure you get 117
Step-by-step explanation:
I'm not sure what the ordered pairs due to you not providing them, but I can tell you the best way to see if they are solutions.
The best way to do so is by substituting the x and y values into the equation.
For example, if you had the ordered pair (5,2), then you would put the x coordinate in place of x and the y coordinate in the place of y.
Like so:
2 = -2(5)+6
The way you know if its a solution is if they equal the same thing.
Solution example:
2 = 2
Non-solution example:
5 ≠ 3

Answer:
%
Step-by-step explanation:
Experimental probability is the actual odds produced from an event. Probability is typically expressed as a fraction of the number of desired outcomes (numerator) over the total number of outcomes (denominator). In this case, the desired outcome is getting heads on a coin flip (23) and the total outcomes is the number of times you flipped the coin (50). Represented as a fraction:
Divide numerator by denominator to get a decimal: 23÷50 = 0.46
Multiply the decimal by 100 to get a percent: 0.46 x 100 = 46%
the coefficient of x is 1
Answer:
3n-1
Step-by-step explanation:
(4n+4) - (n+5)
i sperate it to be
4n-n and 4-5
so
3n-1 should be it
