Answer:
x = 20
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Using ΔAHC , then
∠ACH = 180 - (2x + 100) = 180 - 2x - 100 = 80 - 2x
∠ECD = ∠ACB ( vertical angles are congruent ), thus
∠ECD = ∠ACH + ∠HCB, that is
3x = 80 - 2x + x
3x = 80 - x ( add x to both sides )
4x = 80 ( divide both sides by 4 )
x = 20

The correct option is;
C. The statement is false. The Subtraction Property of Equality should be used first to remove the constant term before dividing
Step-by-step explanation:
In other to solve the equation 4·b + 3 = 11, we have;
By the subtraction property of equality, we have;
Firstly we subtract 3 from both sides gives;
4·b + 3 - 3= 11 - 3
Next we apply the division property of equality, we have;
Both sides of an equation remain equal when we divide both sides of the equation by the same, non-number,
Dividing both sides by 4, gives;
4·b/4 = 8/4
b = 8/4 = 2
The solution to the equation, 4·b + 3 = 11 is b = 2.
(1,3)(3,5)
slope = (5-3) / (3-1) = 2/2 = 1
(3,5)(4,7)
slope = (7-5) / (4-3) = 2/1 = 2
False....they are not collinear because they have different slopes and do not lie on the same line
