In order to solve this you would need to know the original, or sale price of the apples themselves. Do you have this data?
The last step is wrong since if you divide an inequality by a negative, you must also flip the direction of the inequality sign. To solve correctly:
- 6x + 10 > - 44
- 6x > -54
x < 9
i hope this helps! :D
Answer:14
Step-by-step explanation:3 times 2 equals 6 and 6 plus 8 is 14.
Answer:
x= number of songs bought
y= number of movies bought
1.75*x + 2.5*y = 45
x + y = 20
Step-by-step explanation:
Giving the following information:
Robert spent $45 buying songs and movies at an online store that charges 1.75 for each song and $2.50 for each movie he purchased a total of 20 songs and movies combined.
<u>We need to establish a system of equations that represents this situation.</u>
x= number of songs bought
y= number of movies bought
1.75*x + 2.5*y = 45
x + y = 20
<u>Now, we can determine the x and y:</u>
x= 20 - y
Substitute x:
1.75*(20 - y) + 2.5y = 45
35 - 1.75y + 2.5y = 45
0.75y = 10
y= 13
x= 20 - 13
x= 7
<u>Prove:</u>
1.75*7 + 2.5*13 = 45
7 + 13 = 20
