34 = q + n
6.1 = .25q + .05n
-1.7 = -.05q - .05n
6.1 = .25q + .05n
4.4 = .2q
q = 22
22 of the coins are quarters.
Answer:
x = 13
Step-by-step explanation:
These angles are vertical which means they’re EQUAL to each other:
6x + 3 = 81
6x = 81 - 3
6x = 78
x = 13
Complementary angles are angle pairs whose measures sum to one right angle (14 turn,90°, or π2 radians)
2,000,000➕900,000➕30,000➕7,000➕
80➕2
