Answer: 50
Step-by-step explanation:
Let x represent the unknown number
4% × x = 2 or 4/100 × x = 2
25 * (4/100x = 2) * 25
x = 50
Test for x=50
4/100 * 50 = 2
2 = 2
Left side = right side
Therefore, the unknown number is 50
You would add like terms so it would be 1x then you add 1 to 7 so you would get 8.. the you divide both sides by 1x and you'd get 8=x
Sort of..
The mean is all the numbers added together then divided by the amount of numbers there were.
Ex~1,2,3,4,5
Add them all together: 15
Divide by 5 because there is five numbers 15/5=3
The median is the middle number once you put then in order from smallest to largest (or the other way around).
Ex~ 3,5,2,4,1
Rearrange: 1,2,3,4,5
Find the Middle: 3
The median is 3 because it is in the middle of them all once you put them in smallest to largest.
Hope this helped
3/2 and 9/10. Look at the denominators. 2 times what number equals 10. That number would be 5. So if you multiply the first fractions denominator by 5 you get 10. Do the same to the top. you get a new fracrion which is 15/10. Add normally. 15/10 + 9/10 = 24/10. In lowest terms it is 2 2/5 (2 wholes and 2 out of 5)
