Answer:
4
Step-by-step explanation:
A variable term is a mathematical term in which a variable is by itself or is connected to a coefficient(s).
3x3y, 5x2, −4y, z.
The sequence is not geometric or arithmetic because there is no common difference or common ratio between each term.
Not a Geometric or Arithmetic Sequence
x + y = 53
x -y = 9 Adding both equations
2x = 62
x = 31 y = 22
Answer:
N = 3/8
Step-by-step explanation:
let the number be N
let's express the word sentence as a mathematical expression:
"a number multiplied by 2/5"
= "N" multiplied by 2/5
= N x (2/5)
= (2N/5) ------- (1)
"a number multiplied by 2/5 is 3/20" can be written as:
(2N/5) = 3/20 (multiplying both sides by 5)
2N = (3/20) x 5
2N = 3/4 (divide both sides by 2)
N = (3/4) ÷ 2
N = (3/4) x (1/2)
N = 3/8
I think A since working backwards and looking for a pattern wouldn't help, maybe C but im not sure
