Answer:

Okay So I see you need to change 1/3 to a denominator of 6

You don't do anything to the -1/6

But to change the 1/3 you need to multiply 3 and 1 by two, which is 2/6

And the -1/6 stays the same

Find the slope for 11-12

Rama09 [41]

Step-by-step explanation:

To find the gradient:

y2-y1/x2-x1

Pick any two coordinates

11)

(4,3) and (1,-1)

-1-3= -4

1-4= -3

-4/-3 = 1.3(1dp)

12)

(0,1) and ( 2,-2)

-2-1= -3

2-0= 2

-3/2= -1.5

Might be wrong but this is what I got from what I have learnt.

Hope this helps! :)

The sum of Eli’s age and Cecil’s age is 60. Six years ago, Eli was three times old as Cecil. Find Eli’s age now

Nesterboy [21]

Answer:

Eli's age = 42 years

Step-by-step explanation:

Let x be Eli's age and y be Cecil's age

So,

According to the statement given

x+y=60 eqn 1

Eli's age 6 years ago = x-6

Cecil's age 6 years ago = y-6

So according to the given statement

x-6 = 3(y-6)

x-6 = 3y - 18

x-3y = -18+6

x-3y= -12 eqn 2

Subtracting eqn 2 from eqn 1

x+y - (x-3y) = 60 - (-12)

x+y-x+3y = 60+12

4y = 72

y = 18

Cecil's age = 18 years

Putting y = 18 in eqn 1

x+18=60

x = 60-18

x = 42

Eli's age = 42 years ..
