Answer:
x ≤ 6.12
Step-by-step explanation:
If the cost of 1 hamburger in a restaurant is $0.49, the amount of hamburger $3 can buy is expressed as shown
.
$0.49 = 1
$3 ≤ x (since you have maximum of $3 to spend. It cant be more than that)
cross multiply to find the expression for x.
$0.49 * x ≤ $3 * 1
$0.49x ≤ $3
Divide both sides by $0.49
$0.49x/$0.49 ≤ $3/$0.49
x ≤ $3/$0.49
x ≤ 6.12
The number of hamburgers you can buy is represented by the inequality x ≤ 6.12
(y+5) =(5/4)(x-8)
4(y+5)=5(x-8)
4y+20=5x-40
5x-4y=60
Hope that helps you
Easily done! Just do -56 divided by -7 but just remember two negatives equal a positive. So your answer would be 8!
Answer: 45 mph
