Answer:
16) x=13.5 17) x=17
Step-by-step explanation:
*The sum of the interior angles of a 5 sided polygon is 540 degrees.
16) The angle measures are 10x-1, 6x+5, 6x+5, 8x+9, and 8x+9. We add these values up to get 38x + 27. Because the sum of the interior angles must be 540, we set an equation of 38x + 27 = 540. From here, we can make it 38x = 513. Then we divide out the 38 and that leaves us with x = 13.5.
17) In this 5 sided polygon, the angle measures are 139, 5x, 92, 71, and 9x. Like number 16, we add these up to get a sum of 14x + 302 = 540. We subtract out the 302, leaving us with the equation 14x = 238. Finally, we divide out the 14 to get x = 17.
I hope the numbers are right since the values are a bit blurry! If not, just use the same work process to get your answer :)
Answer:
a
Step-by-step explanation:
Answer:
(24x - 48y + 10) / 26 = a
Step-by-step explanation:
-12(-2x+4y) = 26a - 10
24x - 48y = 26a - 10
24x - 48y + 10 = 26a
(24x - 48y + 10) / 26 = a
Answer:
11 < √131 < 12
Step-by-step explanation:
121 and 144 are perfect squares.
11² = 121
12² = 144
√131 = 11.445523
√131 lies between 11 and 12, which are consecutive integers.
Here is an example of children being self reliant.
Most children have parents. Children are self reliant on parents until age eighteen or even later, because they rely on their parents to cook, maintain the house, pay for their food, etc.
I am self reliant sometimes on my friends because I rely on them to give me the answers for math class or to teach me.
