Answer:
<u>1. 1/4</u>
<u>2. 1/6</u>
<u />
Step-by-step explanation:
On a wheel of 8, there are 8 possible outcomes. If you need to spin 2 or 4, that is 2 out of 8 outcomes.
So the probability is 2/8 or 1/4
Rolling a six on a die is a 1/6 chance because there are six outcomes and you want one of them to happen.
Hope This Helps :)
All you have to do is plug in the x and y values for each ordered pair into the left hand side of the equation and see if you get 15 = 15. If you do, the ordered pair is a solution; otherwise it is not a solution. For example, let's try (-2,-3); that is x = -2 and y = -3:
2x - 9y = 15
2(-2) - 9(-3) = 15
-4 - (-27) = 15
-4 + 27 = 15
23 = 15
This is obviously not true, so (-2,-3) is not a solution. Now you try it on each of the ordered pairs given in the problem statement.
Step-by-step explanation:
a) 4x + 8 - 2x + 7
= 2x +15
b) 2n × 5 × 2a
= 10n × 2a
= 20an
