Hi there, please give me the brandies the answer if I helped. The photo is attached below.
Answer:
2nd: 2
4th: -4
11th: -25
Step-by-step explanation:
When you substitute a number into the equation you get that number term. So, if you substituted in 1, you get the first term. To find the second term, you substitute in 2:
A(2) = 5 + (2 - 1)(-3)
A(2) = 5 + (1)(-3)
A(2) = 5 - 3
A(2) = 2
To get the 4th term you substitute in 4:
A(4) = 5 + (4 - 1)(-3)
A(4) = 5 + (3)(-3)
A(4) = 5 - 9
A(4) = -4
And we do the same for the 11th term:
A(11) = 5 + (11 - 1)(-3)
A(11) = 5 + (10)(-3)
A(11) = 5 - 30
A(11) = -25
Answer:
I believe it is 18
Step-by-step explanation:
The last one: x/2=45; x = 90
the problem says: half of a number is 45.
let's use x to represent this number
we know that dividing by 2 halves a number, so, x/2 = 45
to get x alone, we multiply 2 by 2 to cancel it out. so, multiply by 2 on both sides
x/2 • 2 = 45 • 2
x = 90
hope this helped!
