Think of it as putting the x’s on one side of the (>) it’s best to add the smallest number of x’s first so move the -5x to the other side and add it to the -13x after you get that you move the -9 to the other side so it’ll be 2+9 then you divide to get the x alone
Answer: 3
Step-by-step explanation: This is because the 2 numbers are opposites, which cancel each other out, going back to zero.
Answer:
The experimenta probability of picking a 4 is 
Step-by-step explanation:
To determine the experimental probability, we just need to divide the number of observations of the specific event by the total number of trials. In this case, we are interested in the event "picking a 4 card". This event happened 4 times. We have a total number of trials of 50. So , the experimental probability is

supplementary angles add up to 180 degrees
angle 1 = x
angle 2 = 8x
x +8x = 180
9x = 180
x = 180/9 = 20 degrees
larger angle = 8*20 = 160 degrees
