Answer:
x = 50°
2x = 100°
Step-by-step explanation:
Chords AB and DC are equidistant (3 units) from the center E of the circle.
Since, the chords equidistant from the center of the circle are congruent.
Congruent chords intercepts congruent arcs.
Hence, x = 50°
2x = 2*50° = 100°
The expression - x - 9x^2 + 12x^2 + 7 has 4 terms:
-x, -9x^2, 12x^2, 7
Like terms are:
-9x^2, 12x^2
Answer:
Step-by-step explanation:
First we start off by rounding that number to the nearest ten, not tenTH. This rounding would lead to 180$. Now comes the percent part. Here i use the percent equation, which is ____ is ____% of _____. our percent is 10%, and our whole goes at the end, 180$. The part( or the tax), becomes x, and now we translate. Is means = and of means times. so x=.10(180), and x will equal 18
so the tip will be around 18 dollars
