Answer:z
Then variable is n
Variable is an alphabet that depend on number. Then the variable there is n
And the coefficient of the variable is 2
The coefficient is the number behind a variable
And the value of the variable is
2n-3=7
Add 3 to both sides
2n-3+3=7+3
2n=10
Divide both side by 2
2n/2=10/2
n=5
Answer:
15 and 27 are composite
Step-by-step explanation:
prime numbers only factor into 1(x) and x(1)
13 = 1(13), 13(1)
15 = 1(15), 3(5), 5(3), 15(1)
17 = 1(17), 17(1)
27 = 1(27), 3(9), 9(3), 27(1)
