First you right the problem out:
x - 6 = 20 - 19
x - 6 = 1
x = 6 + 1
x = 7
Answer: 7
Answer:
m(C)<m(B)<m(A).
Step-by-step explanation:
1) according to the condition the shortest side is AB, the longest side is BC, the middle is AC. Then
2) the smallest angle is BCA (or C), the middle angle is ABC (or B), the largest angle is BAC (or A).
Answer:
$10 for child tickets and $4 for adult tickets.
Step-by-step explanation:
Let a = price of adult tickets
c = price of child tickets
(1) 12a + 6c = 108 (2) 2a + 12c = 128 Multiply (2) by -6
<u>-12a - 72c = -768</u>
-66c = -660
c = $10 2a + 12(10) = 128
2a + 120 = 128
2a = 8
a = $4
Something is wrong. The adult tickets should be more than the child tickets.
But, according to the info you have given, it comes out to $10 for child tickets and $4 for adult tickets.
