Answer:
88.83
Step-by-step explanation:
To find the mean of a set of numbers is to find the average a set of numbers.
To solve for the mean you have to add all of the values together and divide that sum by the number of values there are.
Ex. 81, 97, 99, 89, 91, 76
81 + 97 + 99 + 89 + 91 + 76 = 533
533 / 6 = 88.83

(number of values)
Answer:
33
Step-by-step explanation:
The two angles add up to 180 degrees because a straight line is 180 degrees
<em>Add both equations and set equal to 180</em>
3m + 138 + 7m +12 = 180
<em>Algebra yeet</em>
<em>Simplify</em>
10m +150 = 180
10m = 30
m = 3
Angle DBC is (7m + 12):
<em>Substitute m = 3</em>
7(3) + 12 = 21 + 12 = 33 degrees
Answer:
37 and 26
Step-by-step explanation:
Let the bigger number be x and the smaller number be y.
Then the two numbers total 63 will give us:
y+x=63------>eqn1
The two numbers have a difference of 11.
y-x=11------->eqn2
We add equations 1 and 2 to obtain:
2y=74
Divide both sides to get:
y=37
Put y=37 into eqn2 to get:
37-x=11
x=37-11
x=26
This larger number is 37 and the smaller number is 26
