Answer:
6
Step-by-step explanation:
30-5=24
24/6=4
or 4 x 6
The natural numbers from 1 to 30:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30.
The prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29.
We have the equations:
x + 3 = 15 and 3y - 1 = 2x - 4
x + 3 = 15 |-3
x = 12
Put the value of x to the second equation:
3y - 1 = 2(12) - 4
3y - 1 = 24 - 4
3y - 1 = 20 |+1
3y = 21 |:3
y = 7
ok hold on
