Answer:
1.
-2 = x/4 + 1
Subtract 1 from both sides:
-2 - 1 = x/4 + 1 - 1
-3 = x/4
Multiply both sides by 4:
-3 * 4 = x/4 * 4
-12 = x
2.
3x+5
3.
X= 12 or 18
This could be read two different ways.
0=2/3x-12
12=2/3x
12÷2/3=x
12*3/2=x
18=x
—-OR—-
0=2/3(x-12)
0=2/3x-8
8=2/3x
8÷2/3=x
8*3/2=x
12=x
Answer:
25%
Step-by-step explanation:
This question is about conditional probability. Let's say that the probability of raining on Saturday is X=true and the probability of raining on Sunday is Y=true. There is a 15% it will rain on both Saturday and Sunday, to put into the equation it will be:
P(X= true ∩ Y = true) = P(X = true) * P(Y = true)= 0.15
There is a 60% chance of rain on Saturday, mean the equation is
P(X = true) = 0.6
The question is asking for the chance of rain on Sunday or P(Y = true). If we substitute the second equation to first, it will be:
P(X = true) * P(Y = true)= 0.15
0.6* P(Y = true)= 0.15
P(Y = true)= 0.15/0.6
P(Y = true)= 0.25 = 25%
Answer:
Step-by-step explanation:
1. 6(a +2b +3c)
2. (6 x 1a) + (6 x 2b) + (6 x 3c)
*Note that I put a 1 in front of the a. I did this because a means there is 1a so by putting the 1 there, it makes it easier to see that 6 x 1= 6, therefore we now have 6a.
3. Answer:
(6a) + (12b) + (18c)
* If you ever have an equation like this that has two of the same letters such as if 12b was 12a, then you could combine those since they are like terms. But since we have three different letters, this is the most simplified answer. Hope this helps!!(: If you have any questions just let me know!
