The integers are x - 1, x and x + 1

x - 1 + x + x + 1 = 186
3x = 186
x = 186/3 = 62

Therefore, the numbers are 61, 62 and 63

Julio bought 4 pencils and 3 erasers for $0.37 and David paid $0.33 for 3 pencils and 4 erasers. What is the cost of one pencil?
grigory [225]

cost of pencil = x = 0.07

and cost of eraser = y = 0.03

Step-by-step explanation:

let cost of pencil = x

and cost of eraser = y

So, we have equations:

4x+3y=0.37\\3x+4y=0.33

Solving both equations to find value of x and y

Let:

4x+3y=0.37\,\,\,eq(1)\\3x+4y=0.33\,\,\,eq(2)

Multiply eq(1) with 4 and eq(2) with 3 and subtract

16x+12y=1.48\\9x+12y=0.99\\-\,\,\,-\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,-\\--------\\7x=0.49\\x=0.07

Putting value of x in equation 1:

4x+3y=0.37\\4(0.07)+3y=0.37\\0.28+3y=0.37\\3y=0.37-0.28\\3y=0.09\\y=0.03

So, x= 0.07 and  y = 0.03

cost of pencil = x = 0.07

and cost of eraser = y = 0.03
