Circle geometry rule: Tangent to circle makes right angle with the radius
Please refer to the diagram below for the working out of each angle
Correct answer is C there are no solutions since the X gets cancelled out and 7 does not equal 8, so the answer is C
Answer:
Adult ticket is $6
Student ticket is $4, as you said.
Step-by-step explanation:
We'll call adult tickets x and student tix y.
14x + 11y = 128
14x + y = 88
First, solve the second equation for y in terms of x:
y = 88- 14x
Then substitute that for y into the first equation:
14x + 11(88-14x) = 128
14x + 968 - 154x = 128
-140x = -840
x = 6 The adult ticket is $6, like you said.
Now take that and solve for y:
y = 88 - 14(6)
y = 88 - 84
y = 4 The student ticket is $4, as you said.
Hope this helps. Feel free to ask questions so you can understand.
25 , 36 and 49
5^2= 25
6^2= 36
7^2= 49
We use them to show if postulated and theorems are correct
