Answer:
The least value of n is 17.
Step-by-step explanation:
First term (a) = 46
Second term (a + d) = 43
Third term (a + 2d) = 40
Common difference (d) = second term - first term = 43 - 46 = -3
Tn (nth term) = a + (n - 1)d
a = 46, d = -3
Tn = 46 + (n - 1)-3 = 46 + (-3n + 3) = 46 - 3n + 3 = 49 - 3n
For Tn to be negative, the product of 3 and n must be greater than 49.
Therefore, the least value of n is 17
6.04 as a fraction in its simplest form is 6 1/25
Answer:
a= -6
Step-by-step explanation:
Given
a=2+3a+10
In order to find the value of a, we have to isolate a on a single side of the equation
So,
subtracting 3a from both sides
a-3a = 2+10+3a-3a
=>a-3a=12
=> -2a = 12
Dividing both sides by -2
=> -2a/-2 = 12/-2
=> a = -6
The value of a in the given equation is -6 ..
Answer:
x=2
Step-by-step explanation:
8x+4=20
Subtract 4 from each side
8x+4-4 = 20-4
8x =16
Divide by 8
8x/8 = 16/8
x=2
