Answer:
<h2>h < 2</h2>
Step-by-step explanation:
5(2h+8) < 60
Expand the terms in the bracket
We have
10h + 40 < 60
Group like terms
10h < 60 - 40
10h < 20
Divide both sides by 10
h < 2
Hope this helps you
Answer:
20% gained
Step-by-step explanation:
25 - 20 = 5
5 / 25 * 100 = 20%
Say x is the number of weeks until their money is equal. Then, we can set up an equation.
400 + 25x = 250 + 75x
Subtract 250 from both sides
150 + 25x = 75x
Subtract 25x from both sides
150 = 50x
Divide by 50 on both sides
3 = x
That means the answer is 3 weeks.
