The probability of getting green is-3/12
And not getting green is -12/3
4x+6 (3x ) - 12 = 4x +6 *3 x - 12
= 4x +18 x - 12
= 22 x -12
Answer:
no.
Step-by-step explanation:
a triangle can only have 180° in total but
60+60+63
=183°
Therefore a triangle can not have these three angles together.
She bought 54 child tickets and 19 adult tickets.
Step-by-step explanation:
No. of tickets purchased = 73
Cost of tickets = $771
Cost of one child ticket = $9
Cost of one adult ticket = $15
Let,
Child ticket = x
Adult ticket = y
According to given statement;
x+y=73 Eqn 1
9x+15y=771 Eqn 2
Multiplying Eqn 1 by 9;

Subtracting Eqn 3 from Eqn 2;

Dividing both sides by 6;

Putting y=19 in Eqn 1

She bought 54 child tickets and 19 adult tickets.
