Bruce is solving a system of equations.

Valentin [98]

Answer:

Option 3,4,5 are correct.

Step-by-step explanation:

The system of equations are:

$3x+5y=9\,\,\,\,(1)\\x-y=-5\,\,\,\,(2)$

Multiply equation (2) with -3 and add with equation (1)

$3x+5y=9\\-3x+3y=15\\-------\\8y=24\\y= 24/8\\y=3$

Value of y is 3

Putting value of y in eq(2)

$x-y=-5\\x-3=-5\\x=-5+3\\x=-2$

Value of x is -2

So, Option 3,4,5 are correct.

How is 0.136¯¯¯¯ written as a fraction in simplest form?

drek231 [11]

Answer:

$\frac{3}{22}$

Step-by-step explanation:

the bar above 36 means that the digits 36 are being repeated

we require 2 equations with the repeating digits placed after the decimal point.

let x = 0.13636.. ( multiply both sides by 10 and 1000 )

10x = 1.3636... (1)

1000x = 136.3636... (2)

subtract (1) from (2) thus eliminating the repeating digits

990x = 135 ( divide both sides by 990 )

x = $\frac{135}{990}$ = $\frac{3}{22}$ ← in simplest form
