Step-by-step explanation:
Answer:
45:20
which can be simplified to
9:4
Hope this helps!
~CoCo
<span>Multiply equation(2) with 4 so that coefficient of become same in both the equations(You can make coefficient of y same and can follow the following procedure.)
</span><span>* Subtract (3) from (1)
* </span>Divide both sides by -19
*Subtract 21 from both sides.
*Divide both sides by 4
so the solution is x= 3 and y= -7
Hope I helped you :)
Answer:
Step-by-step explanation:
<u>Given:</u>
- Tickets cost $12 at the door, number of tickets d
- Tickets cost $8.50 if purchased in advance, number of tickets a
- Minimum target from tickets sold $1050
<h3>Part 1</h3>
<u>Required inequality to meet the goal:</u>
<h3>Part 2</h3>
<u>If a = 36 then minimum value of d:</u>
- 12d + 36*8.5 ≥ 1050
- 12d + 306 ≥ 1050
- 12d ≥ 1050 - 306
- 12d ≥ 744
- d ≥ 744/12
- d ≥ 62
Minimum 62 tickets must sell
