Answer:
45 minutes
Step-by-step explanation:
1/2 hour=30 minutes
2/3 of chapter=30 minutes
1/4 of hour=15 minutes
1/3 of chapter=15 minutes
3/4 of hour=45 minutes
3/3 of chapter=45 minutes
Divide both sides by 1.5
1.5x = 3
x = 2
Check the equation by plugging in the 2.
1.5(2) = 3
3 = 3
Answer:
x = 11
Step-by-step explanation:
- Vertically opposite angles are equal
- Angles around a point add up to 360°
Therefore, 



Answer:
y = -1
Step-by-step explanation:
Notice that the line x = 9 is a vertical line, therefore a line perpendicular to it will be a horizontal line of the form y = constant number.
Since we want it to go through the point (9, -1), then we know that that y value needs to be "-1", and the equation of the line will be given by the expression:
y = -1
Answer:
(-1, 1)
Step-by-step explanation:
Midpoint formula: (x₁ + x₂/2 , y₁ + y₂/2)
Substitute the values into the formula.
(-5 + 3/2 , 3 - 1/2)
(-2/2 , 2/2)
(-1,1)
Therefore, the midpoint is (-1, 1).
