let mona's curent age be y and father's be x 1st case- 3y=x 2nd case-x+12=2(y+12) or x+12=2y+24 since x = 3y 3y+12=2y+24 and y = 12 x = 3*12 x = 36

Let gir's age be y and father's be y+28 Now equation is y+y+5=50 And solve

9 years ago

Ooopsie made a little typo. It's y+y+ 28= 50 But if the question demanded an equation as I mistakenly posted then you may have to convert the value into years and months

I reckon the book has a misprint answer because, my friends said that they had the same concept and had done the solution the same way. Thanks for the help any way reiny. And anyway I am from Nepal not USA.

Digits be x and y and number is 10x+y xy=24 (assuming you meant the product of the digits) And second equation is 10y+x-(10x+y) = 27 Take over

Length = 2* width Let length be l and w be the width Then 2(l+w)=126 2(3w)=126 W=126/6 Find out what you want to find. And please type the full question. That one seems to be just a statement.

But how did you get +√1.5 it's-√1.5 But still according to you the question is incomplete. However if x=0 then you would get a true equation. But how do I solve it to get even at least 0

1-. 87-396 gives a negative value. 2-. Yes 3-. No negative value divided by another negative value gives a positive value 4-. Both your selections are wrong You can type the problems on Google or on a calculator to check them.

3 - wrong 4-wrong again You need some practice with this -20/-10 For your ease Eliminate the negative signs coz - divided by- is plus Now cut the two zeros The you have 2/1 And answer is 2 Try 4 yourself

I don't see any way to solve this one. And you have 3 boxes and all options are odd numbers and you have an even number on the RHS PROBABLY THERE IS SOME TECHNIQUE Or you need to some smartness here 3 factorial gives 6 so 1 solution that I see here is (3!...

Assuming that you meant z=x+(y/2) Or z-x =y/2 Or 2(z-x)=y Otherwise it you meant z=(x+y)/2 Or x+y= 2z Or y= 2z-x

You took 10 as LCM for the first two terms but the second term is negative In your second step you have taken a positive sign Second step must be (3-1)/10
