Adult= A
Children= C
First equation:
A+C= 11
A= 11-C
Second equation:
228 total price includes 22dollar x adult and 15dollar x children ticket price. Write the equation:
228= 22A+15C (substitute above value for adult)
228= 22(11-C) + 15C
228= 242-22C+15C
228 - 242 = 7C
14 = 7C
C= 2 (there are 2 children in the group)
Find adult number, using 11= A+C equation,
11= A+2
A= 9
Check: (9x22) + (2x15) = 228
198 + 30 = 228
Answer: =6x+ −6/5
Step-by-step explanation:
Let's simplify step-by-step.
6x−12/10 =?
= 6x + −6/5

He starts with 15 points, so B and D are out right away. We can remove A, because he needs at least 55 points or more, so C is your answer.
The formula of a volume is V = l*w*h
The prism is 4 cm long, 1.4 cm wide, and 3 cm tall.
4 * 1.4 * 3 = 16.8
The volume is 16.8 cubic cm.
Firs things first you need to know if this is a right triangle.
