Answer:
Tara is 27 and Adam is 31.
Step-by-step explanation:
Tara: x years old
Adam: x+4
Subtract the five years to get their current age
x-5 and x+4-5
x-5 and x-1
(x-5) + (x-1) = 48
x-5 + x-1 = 48
2x - 6 = 48
2x= 48+6
2x= 54
x= 27
Tara is 27 and Adam is 31
Answer:
y = 3 - 2x
Step-by-step explanation:
The goal is to isolate the y variable
In order to have y by itself (on one side of the equation or equal sign), we must move the other numbers and variables to the other side.
Since 2x is on the same side as y, we have to subtract it from both sides. Subtracting it cancels out the original 2x and leaves the equation to look like this:
y = 3 - 2x
Now the y is isolated
Another example:
-5x + y = 15
To isolate the y, we must cancel out the -5x. Add 5x to both sides. It will cancel out the -5x and bring it to the right side of the equation, resulting in:
y = 15 + 5x
Answer: 31.80
Step-by-step explanation:
First you divide 26.50 by 0.20 to get 5.3 then you add that to the starting total and you get your answer which is
Answer: Option 'A' is correct.
Step-by-step explanation:
In the binomial probability formula, we have
Here, n = number of events
x = number of trials
p = probability of success
q = probability of failure
x is the number of trials among which we decide the number of successes and number of failures.
So, Option 'A' is correct.
