The little rectangle in the top right means the angle is a right angle which equals 90 degrees.
This also means all the other angles are also 90 degrees.
Solve for x:
2x+8 = 90
Subtract 8 from both sides:
2x = 82
Divide both sides by 2:
x = 82/2
x = 41
Answer:
(-5,7) is the center
Step-by-step explanation:
The Median is the middle value.
Arrange the numbers in order from smallest to largest:
Seattle: 23.78 , 32.46, 40.30, 45.79, 49.42, 55.14
Since there is an even number, the median is found by adding the 2 middle numbers and dividing by 2.
Median for Seattle: 40.30 + 45.79 = 86.09 / 2 = 43.045
Now do the same for Las Vegas:
2.33, 3.72, 3.84, 4.11, 5.62, 8.79
Median for Las Vegas: 3.84 + 4.11 = 7.95 / 2 = 3.975
Difference: 43.045 - 3.975 = 39.07
The answer is B.
Use order of operations.
-23-20-(-17)+(-5)x(-2)+4x5
Do all multiplication steps.
-23-20-(-17)+10+20
Do all addition and subtraction steps fro left to right.
-43-(-17)+10+20
-26+10+20
-16+20
answer: 4
