The sum of the given angle expressions is 90°, the measure of the right angle:
x + (3x +10) = 90
4x = 80 . . . . . . . . . subtract 10
x = 20 . . . . . . . . . . divide by 4
Answer:
Step-by-step explanation:
Answer: 7 / 18
Step-by-step explanation:
There were 18 students.
Out of them, the scores above 65 are:
73, 73, 69, 68, 71, 76, 70
There are 7 of them.
Probability of picking someone who scored higher than 65 is:
= Number of people who scored above 65/ Total number who took the test
= 7 / 18
5x-4=2x+8
+ 4 +4 Add 4 to both sides
5x=2x+12
-2x -2x Subtract 2x from both sides
3x=12
/3 /3 Divide by 3 on both sides
x=4
It's one because the degree is always after a variable and there is one variable so your degree is one
