(-2,4) (0,4) (-2,7) are the co ordinates
For this case, the first thing we must do is define variables.
We have then:
x: amount of time the assistant works
Y: amount of time the experienced person works
We then have the following system of equations:
x + y = 4
y = (1/2) x
Solving the system we have:
x = 8/3
y = 4/3
Answer:
It would take the roofer, working alone, to complete the same job about:
y = 4/3 hours

Answer:
9°, 9°, 162°
Step-by-step explanation:
Let x represent the measure of the first angle. Then the sum of all of the angles in the triangle is ...
x + x + 9(x+x) = 180°
20x = 180° . . . . . . . . . . collect terms
x = 180°/20 = 9° . . . . . divide by 20
9(x+x) = 162° . . . . . . . find the third angle
The three angle measures are 9°, 9°, and 162°.
Answer: Unlikely
Step-by-step explanation: Given that there’s a 75 percent chance it will not snow, it can be considered unlikely.
11+2x = 8*(x-5)
11+2x = 8x-40
11+40+2x = 8x-40+40
51+2x-2x=8x-2x
51 = 6x
51/6 = 6x/6
8.5 = x
Therefore, your number is 8.5.
