Answer:
x=-4/3y+-2/3z+2
Step-by-step explanation:
add +4y to both sides
then add -2z to both sides
then divide both sides by three
Answer:
You have to do 7x+2+6x+9 Which is 13x+11.
Step-by-step explanation:
Let's start by putting the information on the table into fraction form.
So:
O: 9/20
Y: 5/20
B: 6/20
We now know the probability of picking the different colour chips when the experiment is repeated 20 times but we want to know the probability if the experiment was repeated 80 times. So, we have to find out what number to multiply the probabilities by to get the answer over 80. So:
80/20 = 4
4x9 = 36
Thus the probability of picking an orange chip should be 36/80 and so she should expect to pick up 36 orange chips !
Answer:
x and y do not have a proportional relationship. The constant would be 1.7
Step-by-step explanation:
The reason for this is because as the miles increase they are not following a straight pattern. While 14+14=28 and 28+14=42, 42+14 doesn't equal 70. Even if you think about it in a sense of multiplication, while 14x2=28, 28x2 does not equal 42. What should be done is that the opposite factor of each number should be added together and divided by 3. So 28/14=2, 42/28=1.5, and 70/42=1.6. Then you should take the numbers 2, 1.5, and 1.6, add them together and divide by 3. The answer that you should recieve is 1.7.
Hope that helped.
