Answer:
3
Step-by-step explanation:
IQR is the difference between the upper and lower medians so the IQR = 7 - 4 = 3
A is equal to 87 degrees. You get this answer since all triangle angle measurements must equal 180 when combined. So you add
36+57=93
180-93=87
A=87
Answer:
0.000000001
Step-by-step explanation:
1/1000×1/100000= 1/100000000= 0.000000001
5x + 10 10
---------- = -------
121 11
make the bottom have same common denominator
10/11 x (10/10) = 100/121
Get rid of the denominator (for both now have 121 as a base)
5x + 10 = 100
5x + 10 (-10) = 100 (-10)
5x = 90
5x/5 = 90/5
x = 18
x = 18 is your answer
hope this helps
