Answer: 47°
Step-by-step explanation:
(x + 2)° + (x - 6)° = 90°
x + 2 + x - 6 = 90
2x - 4 = 90
2x - 4 + 4 = 90 + 4
2x = 94
x = 47°
Ok!!!! Bettt let me see th
Answer:
The answer is x = -5
Step-by-step explanation:
In order to find the answer, we first have to put the equation into numerical terms.
14x - 8 = 20x + 22
Now we can solve this using the order of operations.
14x - 8 = 20x + 22 -----> subtract 20 x from both sides
-6x - 8 = 22 ----> add 8 to both sides
-6x = 30 -----> divide both sides by -6
x = -5
<span>3/28 exactly, or approximately 10.7%
Since we're drawing without replacement, let's first calculate the probability that the 1st marble is white. There are 3 white marbles out of a total of 8 marbles. So the probability of the 1st marble being white is 3/8.
Now assuming that the first marble picked is white, the probability of the second marble is 2 out of the 7 remaining marbles. So it's probability is 2/7.
This means that the probability of both marbles being white is 3/8 * 2/7 = 6/56 = 3/28, or approximately 10.7%</span>
