It depends on if you mean that they need to have a whole number or not, if not then they would not need any more because they would already have 1.5 packs. If they do need a whole number then they would need 0.5 more packs
Answer:
18 and 20, 4
Step-by-step explanation:
Math reasoning 1:
Set the first number as x and the other one as x+2 because it is a consecutive even number.
x+x+2=38
2x=36
x=18
18+2=20
The 2 consecutive numbers are 18 and 20
Problem solving 1:
Write out equation first, set the unknown number as x
5+x=9
x=4
3 becuse you put the numbers wrong
