Answer:
A
Step-by-step explanation:
The given angles are vertical and thus congruent, so
3x = x + 40 ( subtract x from both sides )
2x = 40 ( divide both sides by 2 )
x = 20 → A
Answer:
So any time you are multiplying something, you are making "groups of"
so 3 groups of 2 = 6, 4 groups of 3 = 12
But with decimals or fractions, because they are a value less than zero, the numbers become increasingly small instead of bigger, like standard multiplication.
So for example, 1 group of 1/2 = 1/2
2 groups of 1/4 = 1/2
and so on
hope this helps!
