Step-by-step explanation:
When a number is multiplied by 5, the last digit of the product must be 0 (mod 5).
=> Last digit = 0 or 5.
Since 0 is not an option here, the answer must be 5. (C)
Answer:
if youre answer has to be a whole number it would be 3 otherwise it would be x<4 ( so anything less than 4 )
Step-by-step explanation:
so because we are trying to find which company is less, we need to set up in inequality.
so first lets do company A
because 15 is our reoccuring fee, its going to be the coeifficient
so the equation would be
A - 15x + 20
now lets do company B
because it only 20 every month we dont need to have a constant which means the equation for B would be
B - 20x
so lets put it all together
15x + 20 > 20x ( remember our B side has to be less )
now lets solve it
20 > 5x
we know that if x = 4 then the two would be equal, which means our answer would have to be 3 months.
now always check your work.
15 (3) + 20 = 65
20(3) = 60
95/100 = 0.95 <== if she missed 5 out of 95, then she got 95 out of 100
The x-intercepts are: -0.5 and 2.
