Answer: 3

P's coordinates are:  

Y  X

1,  4

1,  2

2,  2

Once we multiply it by 3 it's equal to Q's coordinates.

Y   X

3,  12

Biff is 25 years older than Hannah today. Four years from now,Biff will be 6 times as old as Hannah will be. How old is Hannah t
gavmur [86]

Hannah is 1 year old today.

Step-by-step explanation:

Let,

Hannah = x

Biff = y

According to given statement;

y = x+25   Eqn 1

In four years;

y+4 = 6(x+4)   Eqn 2

Putting value of y from Eqn 1 in Eqn 2;

(x+25)+4=6x+24\\x+25+4=6x+24\\x+29=6x+24\\29-24=6x-x\\5=5x\\5x=5

Dividing both sides by 5

\frac{5x}{5}=\frac{5}{5}\\x=1

As x is age of Hannah, therefore,

Hannah is 1 year old today.

Two less than a number is 10
Murljashka [212]
X-2=10
or
10=x-2
this is because it says "2 less than a number is 10" so we can infer that 2 is less than a number (x) so knowing that less than means subtract x-2=10 or you can put it as 10=x-2
