A and B are not.
The answer is 465 and you are welcome
Answer:
x = -5/2 - sqrt(13)/2
x = sqrt(13)/2 - 5/2
"sqrt" means the square root of
Step-by-step explanation:
We know there is a total of 100 cups of tea sold and that there are two types of teas involved.
x = tea 1
y = tea 2
We can set up two equations and use substitution to solve:
x + y = 100 cups of tea sold total
One of the teas sold 5 times as much as the other. Let's believe that this was tea 1:
x = 5y (5 times as much means multiplication, and 'other' means y)
If x = 5y, then this must be true for the first equation. So we'll test this by plugging it in:
5y + y = 100
6y = 100
y = about 16.67
Now we can use this number to solve for x in the original equation:
x + 16.67 = 100
x = 83.33
1. True
2. True
3. False-It would be true if the lines were parallel, but they are not. Therefore, <4 and <7 are not corresponding angles.
4. False-<4 is 80 degrees and <7 is 90 degrees.
5. True
6. False-<8 measures 90 degrees because its vertical angle is 90 degrees.
7. False-Line o is not parallel to lines m and n because m and n has 100 degree and 80 degrees angle measures, but line o only has 90 degrees angle measures
8. True
