Answer:

2.3lego

Step-by-step explanation:

We can walk through this problem using the cross multiplication method

First 3 1/2 lego is same as 3.5lego

Hence If

Johnny builds 3.5lego in 60min

He can build xlego in 40min

Crosss multiplying we have

Xlego *60= 3.5*40

Xlego= 140/60= 2.3lego

Answer:

The solution is (3,2)

Step-by-step explanation:

x - y = 1 →equation 1

-x + 3y = 3 →equation 2

by elimination method,

x - y = 1

-x + 3y = 3

-----------------

0 + 2y = 4

2y = 4

y = 4/2

y = 2

substitute y=2 in equation 1

x - y = 1

x - 2 = 1

x = 1 + 2

x = 3  

∴(3,2) is the solution

Transform into y=mx + b form: - 2x + 6y = - 24
ziro4ka [17]

Answer:

y= 1/3 x-4

Step-by-step explanation:

-2x+6y=-24 Write what you are given

+2x        +2x Add 2x to each side to get y by itself

------------------

     +6y=-24+2x

       /6    /6 Divide by six on both sides to get y by itself

-----------------

         y=-4+ 1/3 x

         y= 1/3 x-4 Rearrange to get into y=mx+b form
