Answer:
14
Step-by-step explanation:
mean= (12+11+13+10+m)/5
12/1=( 46+m)/5
12*5=46+m
60-46=m
m=14
Answer:
b= 70
Step-by-step explanation:
The sum of the opposite interior angles of a triangle is equal to exterior angle.
a+b = 140
We know that a = b since PQ = RQ The angles opposite the equal sides in an isosceles triangle are equal
b+b = 140
2b =140
Divide by 2
2b/2 =140/2
b= 70

Answer:
29/22
Step-by-step explanation:
Let x = 1.31818181818....
Then, 10x = 13.18181818..., and 1000x = 1318.18181818..... Subtracting the first equation from the second, we get that 990x = 1305. This means that x = 1305/990. In lowest terms, this is 29/22.
Answer:
10
Step-by-step explanation:
2x^2-x-5= 2x^2-6x + 5x -15 +10= 2x(x-3) +5(x-3) + 10= (2x+5)(x-3) + 10
(2x^2-x-5)/(x-3)= 2x+5 + 10/(x-3)
So the remainder is 10
