To tell whether r = 2 is a solution of the inequality, substitute 2 for r and see whether the inequality produces a true or a false statement.
(2) + 4 > 8, add 2 and 4.
6 > 8, this is a false statement, because 6 is not greater than 8, so the value r = 2 is not a solution of the inequality r + 4 > 8.
X/32 = 80/100
^to solve use cross products
32 x 80 = 2560
2560 ÷ 100 = 25.6
$32 + $25.60 = $57.60

When pam saves 2, brother saves 5
so if Pam has 40
40/2 (the number of dollars Pam saves) = 20
20 x 5 = 100 ( the number of dollars her bro saves)
her bro has 100 dollars
hope this helps
basically divide 2 from 40 and then multiply the answer with 5, and you get the number of money her bro saves
hope this helps
