Answer:
11
Step-by-step explanation:
First, we need to find the other angles. We'll do this by subtracting 180-141, giving us 39. This is one of the angles needed.
Next, we'll find the other angle by subtracting 180-127, giving us 53.
Now, we can set up the expression: 39 + 53 + 8y = 180
Adding like terms: 92 + 8y = 180
Now, subtracting 180-92 to give us 8y = 88
Diving both side by 8, gives us the value of y = 11.

Answer:
The first three statements are correct, the other two are wrong
Second to last problem: WRONG - Since the second to last problem is marked down by 40% we subtract 40% from 100% to get 60%. Now we just do 0.60*28 = 16.8 which makes the statement wrong.
Last problem: WRONG - The last one is marked down by 50% so that is 100% - 50% to get 50%. We do 0.50 * 28 to get 14, making the statement wrong.
The first 3 statements are correct, and the 2 last ones are wrong

Brainiest is most appreciated:)
Answer:
8
Step-by-step explanation:
the ratio or fraction for this problem would be 1 (gold coin) : 25 (points)
If we want to find out how many gold coins he needs to get 200 points we need to divide 200 by 25.
200/25 : 8
if we want to check our answer do this
1:25
1 x 8 is 8
25 x 8 is 200
Soo... Collin needs to find 8 coins to win 200 points.
hope i helped
49x^2 - 9 = 0
As there is no x term, we can pretty much guess we have a situation where we factlrise by something known aa difference of two squares, so to factorise it:
49 = 7^2
9 = 3^2
x^2 = (x)^2
so...
(7x - 3)(7x + 3) = 0
7x - 3 = 0 7x + 3 = 0
x = 3/7 x = -3/7
