Let's write it down in mathematical terms:
x-y=5
so
x=5-y
this means:difference between two numbers is 5
2y=x+18
this means: twice the smaller number is 18 more than the larger number
and we can substitute the x for what we said before:
2y=(5-y)+18
we add 1 y from each side:
3y=5+18
3y=23
so the smaller number is 23 and the bigger number is 23+5=28.
2 i believe because if .25 is equal to 1/8 then that mean the 4/8 would be equal to 1 and in turn 8/8 would equal 2.
Answer:
$522.60
Step-by-step explanation:
pencils: $4.10 * 6 ===> $24.60
pens: $6.50 * 12 ===> $78
notebook paper: $105 * 4 ===> $420
pencils + pens + notebook paper = total cost
24.60 + 78 + 420 = 522.60
