Answer:
x > 7
Step-by-step explanation:
you move over the 10 to the left and it becomes negative.
x > 17 - 10
so then you subtract the 17 - 10 and you would get 7.
x > 7
Prime numbers have only 2 factors 1 and its number for example:
2, 3, 5, 7, 11, 13, 17, 19, 23
Like this 1*2. Or 3*1
Composite numbers have more than two factors for example :
0, 4, 6, 8, 9, 10, 12, 14 15, 16..
For example 0 has many factors
0 times 3 0times 4
The answer you selected is correct
3x - 4y = 16
3x = 4y + 16
x = 4y/3 + 16/3
Answer:
Number of dogs = 6
Number of burgers = 11
Step-by-step explanation:
Number of dogs = x
Number of burgers = 2x - 1
Cost of a dog = $ 1.50
Cost of 'x' dogs = 1.5x
Cost of a burger = $ 2
Cost of (2x - 1) burger = (2x -1) * 2 = 2x *2 - 1*2
= 4x - 2
Total amount collected = $ 31
1.5x + 4x - 2 = 31 {add 2 to both sides}
1.5x + 4x = 31 + 2
1.5x+ 4x = 33
5.5x = 33
x = 33/5.5
x = 6
Number of dogs = 6
Number of burgers = 2*6 - 1 = 12 - 1 = 11
