Answer:
x times 8 I'm pretty sure
Answer:
39
Step-by-step explanation:
Let x = son's age
Then 3x = Carlos' age
So, x + 3x = 52
4x=52
x=13
So the son is 13 and Carlos is 3x13=39
Answer
A
Step-by-step explanation:
First, lets go through B-D and explain why they are correct.
B= f represents the number of flash drives. This means that the coefficient, 10, would be the cost per flash drive.
C= n represents the number of cases of paper. it says so in the question, so that one is a bit easier.
D= f represents the amount of packages of hanging folders. If the coefficient for B is the cost, then that would be the same case for D. Therefore it is correct because the coefficient is 13.
A would be incorrect because the coefficient represents the amount that one item costs. P is the packs of pencils, meaning that it would be $7 per pack of pencils.
Hope this helps!
b.there will be only one solution
c.there will be 2 solutions but they will both be negative
d.there will be 2 solutions but they will both be positive
the
e.none of these
Answer:
e. none of these
Step-by-step explanation:
The correct answer is e. none of these because a negative discriminant means that there will be no solutions at all!
