Answer:
49
Step-by-step explanation:
x + 100 + 31 = 180
x + 100 + 31 - 100 - 31 = 180 -100 -31
x = 49
In a trapazoid the diagonals are the same so therefore the two equations equal echother
3x+7=5x-11 solve for x by combining like terms
18=2x then divide to unto multiplication
9=x
9 is the value of x
I hope I've helped!
Answer: A quadratic graph can have two x-intercepts
2 x pi radians = 360 degrees, [remember this formula]
2 x 3.14 = 6.28 radians = 360 degrees
therefore 1 radian = 360 degree/ 6.28 or 57.32 degrees approx.
3.5 radians is therefore = 57.32 x 3.5 = 200.62
closest answer would be b ) 200.54 degrees
If Brandi purchases x albums and y singles, then x albums cost $10x and y singles cost $y. She wants to spend no more than $25 total, then

Brandi wants to purchase at least 5 singles. This means that

Note that x and y are whole numbers.
There are three possibility:
- x = 0, y = 25 (the total cost is 10·0 + 1·25 = 25 ≤ 25 and 25 singles is more than 5 singles);
- x = 1, y = 15 (the total cost is 10·1 + 1·15 = 25 ≤ 25 and 15 singles is more than 5 singles);
- x = 2, y = 5 (the total cost is 10·2 + 1·5 = 25 ≤ 25 and 5 singles is equal to minimal required number of singles).
Answer: 1) 0 albums and 25 singles;
2) 1 album and 15 singles;
3) 2 albums and 5 singles.
