Maths Homework Help For My Sister? Easy Ten Pts!!?

Question

Can You Solve These Questions...Though Im elder But I dunno Y I Cant Solve Them.....Ten Points For Who Can Answer These Questions Correctly! Remember to Explain It Using Formula...:P

1) Tom's Mother Is 6 Times His Age Presently. Five Years hence,she will be 20 Years Older Than Tom. What Are Their Present Ages?

2) The Length Of A Traingle Is 1.5 Times Its Width, If The Perimeter Is 40, What Are The Length And Width? If The Same Perimeter Is Used To Make A Square, What Is The Square's Area?

Answer 1

1) (6x + 5)-(x + 5) = 20   [x represents tom's age]

5x=20

x=4  his mother is 24 right now

2) 2*1.5w + 2*w = 40 [w represents the width]

3w+2w= 40

5w=40

w=8   the length is 12.

if the perimeter is used to make a square:

40/4 = 10 to determine the length of each side

10*10= 100, which is the area of this square

p.s. this guy above me is totally wrong on the 1st one...

if tom is 3 right now and his mom is 18, in 5 years, he will be 8 and hi smom will be 23....

Answer 2

well i can answer question number two.

the first part though.

you will have to divide

40 divided by 1.5 but of course that would equal a repeating decimal of 26.66666...

so then you multiply that by 1.5 and then that would be your answer.

now for the second part.

the area is 100.

since the perimeter is 40. and there is four sides.

all sides are equal so each side is 10.

the area for a square is bh=a

so 10x10=100.

now for number one.

what is hence?
