Answer:
The output is 3n + 6
Step-by-step explanation:
You have to apply all of the steps in order:
Since we cannot simplify n+2, we have to write it as (n+2). Next, since we do the next step, multiply by 3. This would be 3(n+2), and if you apply the distributive property (multiply), you would get 3 * n + 2 * 3, or 3n + 6.
Answer: 3n + 6
Answer:
1st odd = 71
2nd odd = 73
3rd odd = 75
Step-by-step explanation:
As numbers are consecutive odd so let:
1st odd = x
2nd odd = x + 2
3rd odd = x + 4
According to given condition:
x + x +2 + x + 4 = 219
Adding like terms
3x + 6 = 219
Subtracting 6 from both sides
3x + 6 -6 = 219-6
3x = 213
Dividing both sides by 3
x = 213/3
x = 71
So the numbers will be:
1st odd = x = 71
2nd odd = x + 2 = 71 + 2 = 73
3rd odd = x + 4 = 71 + 4 = 75
Proof:
1st odd + 2nd odd + 3rd odd = 219
71 + 73 + 75 = 219
219 = 219
Hence proved!
I hope it will help you!
Hello there!
There are 10 marbles and 2 of them are red. First pick is 2/10 to get a red and then if you pick a red marble then you have a 1/9 chance to pick a red.
So, 2/10 x 1/9 = 2/90
Simplify 2/90 to get 1/45.
Convert 1/45 to a decimal.
1/45 : 0.022222
Therefore, the probability to the nearest 10th of a percent that both marbles drawn will be red is 0.02%
Start with parenthesis so that will be 7x -21so then you will get 4x = 7x -21 then you will subtract 7x and 4x and you will get -3x = -21 and your answer is 7 because both numbers are a negative and that will equal a positive.
Answer:
Step-by-step explanation:
Well the first fact is that you can solve H and J with 1 equation. Two remote (unconnected to) one of the exterior angles when summed, equals the unconnected exterior angle.
H + j are not connected to the exterior angle at I.
Put more directly
2x + 3x = 150 Combine
5x = 150 Divide by 5
x = 150/5
x = 30
So H = 2 * 30 = 60
and J = 3*30 = 90
All triangles have interior angles that add up to 180
We have already accounted for 150.
JIH + 150 = 180 Subtract 150
jIH = 180 - 150 = 30
Summary
x = 30
JIH = 30
H = 60
J = 90
