I’m going to say the top one it seems like that would be correct
Answer:
x=72
y=54
Step-by-step explanation:
1st question. y=54 because it is a bisector of the 108 degree angles. (a polygon's interior angles add to number of sides minus 2 times 180)
There are two ys, so they add up to 108. A triangle's interior angles add to 180. 180-108 =72 x=72
2nd question, x is 72 ( it says x is the same measure) so 180-72=2y.
y still equals 54
Answer: Infinite solutions
Step 1: Turn this into y=Mx+b form
The current equation is—
-2x+5y=30
Since we want to get y alone on the left side, let’s add 2x on both sides
-2x+5y=30
+2x +2x
____________
5y=2x+30
Step 2: Again, trying to get y alone, we need to divide 5 on both sides
5y=2x+30
/5 /5 /5
________
y=2/5x+6
Step 3: Now that we know how to find y, substitute that in where y is in the equation
-2x + 5(2/5x+6) = 30
-2x + 2x + 30 = 30
30=30
Seeing that you cannot get a specific answer for y when solving, there is an infinite number of solutions

Step-by-step explanation:
whether it's a negative or positive, absolute numbers are always positive!!
Answer:
22.45%
To two decimal places
Step-by-step explanation:
A book has 245 pages and she has only read 55 of the pages. To get the percentage:
55/245 and then multiply it by 100.
55/245
=O.2245 (To four decimal places)
0.2245 x 100
22.45% (To two decimal places)
She has only read 22.45% of the book. To convert it to a whole number, that's 22% of the book has been read
