Answer:
52 cards
Step-by-step explanation:
call the amount he started with " x "
then he bought 8 cards
so the new equation is
x+8
then he lost half of his cards
so now the equation is
(x + 8 )/2
that amount to 30 cards as per what is given in the problem
so now the equation is
( x + 8 )/2 = 30
solve using inverse operations and simplifying
( x + 8 )/2 = 30
*2 *2
x + 8 = 60
-8 -8
x = 52
Answer:
y+7=2(x+10)
Step-by-step explanation:
we find the slope
you can simplify but its already in point slope form
but here it is if you are curious and want to double check it is
y=2x+13
we can also check our work
-7=2(-10)+13
-7=-7
