Answer:
$4.57. Hope this helps :)
Step-by-step explanation:
20+5=25
then you do
25-3.67= $21.33
you then divide that by the number of pounds she bought.
21.33/4= 5.3325
round that to the hundreths place and you get $5.33
so she paid $5.33 for a pound
Answer:
47 cards remain
Step-by-step explanation:
thank you
pls follow me.
The answer to this equation is: x=5.5
The digits are x and y
multiply sum of digits by 7
7(x+y) you get the original number which would be 10x+y
so
7x+7y=10x+y
if reverse digits, new number is18 more than sum
10y+x=18+x+y
so we got
7x+7y=10x+y
10y+x=18+x+y
we can minus x+y from both sides in all the equations to obtain
6x+6y=9x
9y=18
last one, divide both sides by 9
y=2
sub back
6x+6y=9x
6x+6(2)=9x
6x+12=9x
minus 6x both sides
12=3x
divide both sides by 3
4=x
the number is 42
why did you write it down there, oh well
