2.) If ZA = (20 – 2m)º and ZD = (m – 130°, what is the value of m?

vivado [14]

Answer:

m = 50

Step-by-step explanation:

∠ D and ∠ A are vertically opposite angles and are congruent , then

m - 130 = 20 - 2m ( add 2m to both sides )

3m - 130 = 20 ( add 130 to both sides )

3m = 150 ( divide both sides by 3 )

m = 50

I think of a number and add one fourth of it to half of it and the result is twelve. What is the number I thought of?

belka [17]

Suppose that the number u were thinking about is x thus :

$\frac{1}{4} x + \frac{1}{2} x = 12 \\$

Multiply both sides by 4

$4 \times ( \frac{1}{4} x + \frac{1}{2} x) = 4 \times 12 \\$

$x + 2x = 48$

$3x = 48$

Divide both sides by 3

$\frac{3x}{3} = \frac{48}{3 } \\$

$x = 16$
