Slope is -2/5 and y-intercept is 2
Step-by-step explanation:
- Step 1: Write the equation in slope-intercept form y = mx + b
2x + 5y = 10
5y = -2x + 10
y = -2/5 x + 10/5
y = -2/5 x + 2
- Step 2: Find the slope and y-intercept from the equation.
Slope, m = -2/5
y-intercept, b = 2
1 hour = 60 minutes.
Convert the minutes to decimals by diving by 60
30/60 = 0.5
2 hours and 30 minutes = 2.5 hours
45/60 = 0.75
5 hours 45 minutes = 5.75 hours
15/50 = 0.25
3 hours 15 minutes = 3.25 hours
Ow add all the hours:
2.5 + 5 + 5.75 + 3.25 = 16.5 hours
Answer: B. 16.50
Let's say that y is the unknown
180=2x+3+5x+1+y
180=7x+4+y
180-7x-4=y
176-7x=y=third angle
