Answer:
<u>The numbers are 12 and 32.</u>
Step-by-step explanation:
x = One number
x - 20 = Another number
3x - (x - 20) = 84 (If the lesser number is subtracted from three times the greater number, the difference is 84)
Let's solve for x, this way:
3x - (x - 20) = 84
3x - x + 20 = 84
2x = 84 - 20 (Subtracting 20 at both sides)
2x = 64
x = 64/2
<u>x = 32 ⇒ x - 20 = 12</u>
The amount after the reduction of 15% for 100 = 85
<span>the amount after the reduction of 15% for 150 = (85/100) * 150</span>
= 127.5
Answer:
the duplicate ratio of a : b
= a²/b²
Step-by-step explanation:
for example:-
for understanding
if u wanna find the duplicate ratio of 4:5
so,
4²/5²= 16/25
•°• 16:25
16:25 is your duplicate ratio of 4:5
The answer is 10:00 am
add 3 to 6 then add the 30 minutes to the 30 minutes which equals another hour
Answer:
I have a formula for differentiating a questions on differentiation
Step-by-step explanation:
I have not published it yet but can give a brief summary of it will later use it to solve questions here after publishing it
any time you a given a function or a question to differentiate always write it in this form y=am...will explain the rest later after publishing it. it works for all kind of differentiation questions like product or quotient type of questions
