Answer:
x <6
Step-by-step explanation:
5x-9 < 21
Add 9 to each side
5x-9+9 < 21+9
5x< 30
Divide each side by 5
5x/5 <30/5
x <6
8*10= 80
You now know how many Jerome has.
3*10= 30
That is how many his sister has.
80-30= 50
Jerome has 50 cards left.
I hope this helps!

The answer for this one is C
well, let's check the graph, and use two points off of it..hmmmm it passes through (4, 0) and it also passes through (0, -4).
so, what would be the equation of a line that passes through those two points?
keeping in mind that
standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
