"<span>y/5+8=7, what is the value of y/5-2?" Simplify the first equation:
y/5 = 7 - 8, or -1, so y/5 = -1, or y = -5.
Then y/5 - 2 equals -5/5 - 2, or -3.</span>
Answer:
200.96
Step-by-step explanation:
divide the diameter by 2, to get 8. then multiply 8 by 8 to get 64. 64×3.14 is 200.96
Let s represent the measure of the second angle.
The measure of the first angle is 15° less than the second, so we can represent the first angle by (s-15).
The measure of the third angle is 45° more than half the second, so we can represent the third angle by (45+(s/2)).
The sum of these angles is 180°, so we can represent the sum as
... (s-15) + s + (45+s/2) = 180
Collecting terms, we have
... 2.5s +30 = 180
... 2.5s = 150 . . . . . . subtract 30
... s = 150/2.5 = 60 . . . . divide by the coefficient of s
The first angle is 60-15 = 45.
The second angle is 60.
The third angle is 45+60/2 = 75.
_____
<u>Check</u>
The sum of the three angles is 45 +60 +75 = 180.
The statement is totally false.
because (P and ¬P) is a contradiction.
