Tenths is 73.9 hundredths is 73.91
Answer:
Step-by-step explanation:
Well if x is equal to then the dot will be colored and because it is less than then it will go to the minus sign and so it will be colored on 1 and then go to the negative side to infinity
Hope this helped
Answer:
(x,y) = (3, 1/2)
Step-by-step explanation:
This pair of linear equations may be solved simultaneously by using the elimination method. This will involve ensuring that the coefficient of one of the unknown variables is the same in both equations..
To solve this, add the equations;
x + 2x + 2y - 2y = 4 + 5
3x = 9
x = 3
substitute the value of x into the first equation,
3 + 2y = 4
2y = 4 -3
2y = 1
y = 1/2
Answer:
Step-by-step explanation:
There might be a shorter way of doing this and a better one as well, but here is how I did it.
Let the three numbers be
Solution
Note that these three numbers are consecutive and even.
Twice the smallest number is 2 * (2n - 2)
20 more than the second number is 2n + 20
Now equate them.
2(2n - 2) = 2n + 20 Remove the brackets.
4n - 4 = 2n + 20 Add 4 to both sides
4n - 4 + 4 = 2n + 20 + 4
4n = 2n + 24 Subtract 2n from both sides.
4n - 2n = 2n - 2n + 24
2n = 24
Now stop
Answers
- The middle number is 24
- The smallest number is 24 - 2 = 22
- The largest number is 24 + 2 = 26
Check
22*2 = 44
The middle number = 24 + 20 = 44
