Answer:
n= 42
Step-by-step explanation:
Given expression is: 3(n-5)-2(n+8)=11
Now, first of all we will multiply the numbers which are outside the brackets to the numbers inside. Which will become:
3n-15 - 2n - 16 = 11
Next the second step is to the change the positions. The numbers that are multiplied by n will be together:
3n - 2n -15 - 16 = 11
Finally, by solving the above equation. We get:
n - 31= 11
n = 11+ 31
n= 42
Required answer is n = 42
Answer:
n=42
Step-by-step explanation:
The first step is to open the brackets by multiplying the vale before the brackets to the values inside the brackets giving attention to the signs which gives:
3n-15-2n-16=11
Then we collect like terms together.
3n-2n-15-16=11
evaluating the above equation we get
n-31=11
n=11+31
=42

Answer:
34
Step-by-step explanation:
F(x) = 2x^3 - 7x + 1
Let x= 3
F(3) = 2* 3^3 - 7*3 + 1
= 2 * 27 -21+1
= 54 -21 + 1
= 34

Answer:
-293
Step-by-step explanation:
The first term of the arithmetic sequence is a1 = 2. The common difference is d = -3-2 = -5. The general term is ...
an = a1 +d(n -1)
an = 2 -5(n -1)
The 60th term is ...
a60 = 2 -5(60 -1) = -293
