Solve the equation by completing the square. Round to the nearest hundredth if necessary.

x^2+3x-5=0

1.66, 2.69

1.05, –4.05

1.19, –4.19

–8.75, 5.75

1•19,-4•19

Step-by-step explanation:

x²+3x-5=0

x²+3x=0+5

x²+3x/2=5

x²+(3x/2)²=5+9/2

√(x+3/2)²=19/2

x=19/2-3/2,19/2+3/2

x=1.19,-4.19

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
