A) W + Y = 29
B) 11.95 W + 11.50 Y = 338.90
Multiply equation A by -11.5
A) -11.5 W + -11.50Y = -333.50 then add to B)
B) 11.95 W + 11.50 Y = 338.90
.45 W = 5.4
W = 12 and so
Y = 17
Around 0.139 or 0.40, divide 2.79/20
The answer is 23/40 . Hope this helps
Step-by-step explanation:
Create an equation such that x equals the decimal number.
Count the number of decimal places, y. Create a second equation multiplying both sides of the first equation by 10y.
Subtract the second equation from the first equation.
Solve for x.
Reduce the fraction.
