Solve the inequality<br> 7y+2&lt;5y+12
Zanzabum

Answer:

y < 5

<h2><u>Step by step:</u></h2>

Step 1: Subtract 5y from both sides.

7y+2−5y<5y+12−5y

2y+2<12

Step 2: Subtract 2 from both sides.

2y+2−2<12−2

2y<10

Step 3: Divide both sides by 2.

\frac{2y}{2}  < \frac{10}{2}

= y < 5

a museum opened at 8:00 am. in the first hour 350 people purchased admission tickets. in the 2nd hour 20% more people purchased
Levart [38]

Okay, so we already know that 350 people purchased tickets in hour 1:

17.50(350 + ?) = ?

The question states that in the 2nd hour, there was 20% more people. So basically, we solve for 120% of the people from the 1st hour:

17.50(350 + 1.2(350)) = ?

Multiply 1.2 by 350:

17.50(350 + 420) = ?

Add:

17.50(770) = ?

Multiply:

17.50(770) = 13475

$13,475 was the total amount of money.
