Answer:
-10 sqrt(10)
Step-by-step explanation:
-2 sqrt(250)
We know that sqrt(ab) = sqrt(a) sqrt(b)
-2 sqrt(25*10)
-2 sqrt(25)*sqrt(10)
-2 *5*sqrt(10)
-10 sqrt(10)
22/7 -2/3= 20/4
20/4×1/2=20/8
you need simplifly
so is 4/2
Answer:
Step-by-step explanation:
The key to answering this is to know that the only time you'll change the direction of the sign is when you multiply or divide by a negative number.
-46 - 8x > 22
-8x > 22 + 46
-8x > 68
x < 68/-8 (we divided by -8 so the inequality changed direction)
x < -17/2
Answer:
For the sum of the digits of Michelle’s father to drop to 1/3 of its’ former value, the second digit must go from 9 to 0, in one year.
Thus, if he is 39 this year, the sum of the digits of his age will be 12. Next year, when the sum of the digits would be 4+0, or 4, then the digits of his age would be 1/3rd of their former value.
Therefore, he is 39, and will be 40 next year
