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
Answer:
7.5
Step-by-step explanation:
Answer:
The answer is 8
Step-by-step explanation:
p + 99 = 107
p + 99 – 99 = 107 – 99
p = 8
Thus, The value of p is 8

It is B. Because the 3$ doesn't have any variables and the 2 dollars is per hours so 2x
<h2>Explanation:</h2>
In this exercise, we have the following equation:
We can write this Quadratic Equation in Standard Form as follows:
So this is a Non-perfect Square Trinomial. To factor out this, let's choose two numbers such that:
- The sum is -14
- The product is 24
Those numbers are:
- -12 and -2
- SUM: -12-2 = -14
- PRODUCT: (-12)(-2)=24
So we can write this as:
