Bill has 12 cards. I figured this out by making a table and drawing an equation:
Hi!
We can remove the parentheses.
2m+3+4m+3=0
Simplify by combining like terms.
2m+4m+3+3=0
6m+6=0
Subtract 6 from both sides.
6m+6-6=0-6
6m=-6
Divide by 6 on both sides.
6m/6=-6/6
m=-1
The answer is m = -1
Hope this helps! :)

Answer:
x=6
Step-by-step explanation:
-6(6+5x)-4=-220
-36-30x-4=-220
-40-30x=-220
30x=-40-(-220)
30x=-40+220
30x=180
x=180/30
x=6
Answer:
19/70 of NASA shuttle missions were carried out by Discovery.
9/140 of NASA shuttle missions were carried out by Challenger.
17/70 of NASA shuttle missions were carried out by Endeavour.
Step-by-step explanation:
Adding the number of missions carried out by NASA gives us 140 in total.
Discovery's total amount of missions simplified is 19/70.
Challenger's total amount of missions is already in the simplest form.
Endeavour's total amount of missions simplified is 17/70.
