30 3/4 + 12 1/4 + 16 1/4 = 59 1/4
72 - 59 1/4 = 12 3/4
Buenos tardes!
Answer:
The 85 term of the arithmetic sequence would be 983
Step-by-step explanation:
Use the formula: an=a1+(n−1)d
an=a1+d(n-1)
a85= -25+(85-1)12
a85= -25+1008
a85=983
Answer:
I think it might be 154 not sure tho
Answer:
The correct option is C....
Step-by-step explanation:
First of all multiply the terms:
(x-6)(x+8)=0
x^2+8x-6x-48=0
Now solve the like terms:
x^2+2x-48=0
Now we will solve this quadratic equation by factoring:
The first terms has coefficient 1. So 1 will be multiplied by the constant term 48.
1*48= 48
Now we have to find out the two values whose product is 48 and whose sum or difference is 2(middle term).
8*6 = 48
8-6 = 2
Now break the middle term:
x^2+8x-6x-48 = 0
Now take the common from the first two and last two terms:
x(x+8)-6(x+8) = 0
(x+8)(x-6)=0
x+8=0 , x-6=0
x= 0-8 , x=0+6
x = -8 , x=6
Thus the solutions we get are: x=6 or x= -8
The correct option is C....
Answer:
15:20
Step-by-step explanation:
3 + 4 = 7
35 / 7 = 5
5 x 3 = 15
5 x 4 = 20
Therefore the answer is 15:20
