<em>2400 is increased by 30%.</em>
so,
2400 + (30/100 * 2400)
2400 + (30 * 24)
2400 + 720
3120
<em>this number is decreased by 20%.</em>
3120 - (20/100 * 3120)
3120 - (2 * 312)
3120 - 624
2496
therefore, the final number will be 2496.
Answer:
x = 72
Step-by-step explanation:
Answer:76
h = 9.674
x = 37 y = 12
Let x be one number
Let y = other number
x+y = 49
x-y = 25
Add the equations together
---------------
2x = 74
Divide by 2
2x/2 = 74/2
x =37
37+y = 49
Subtract 37 from each side
37+y-37 = 49-37
y = 12
