have a nice day
Step-by-step explanation:
(x-73) + (x-65) = x
2x - 138 = x
2x - x = 138
x = $138 cost of the bike
Ask which two numbers add up to -11 and multiply to 30?
That would be; -6 and -5
Rewrite the expression using what you have above;
<u>(x - 6)(x - 5)</u>
Answer: $10
Step-by-step explanation:
Let adults tickets be denoted by a
Let student tickets be denoted by s
On the first day of tickets sale, there were 10 adult tickets and 11 students tickets sold for a total of $190. This will be:
10a + 11s = 190
The second day, there were a total of $160 worth of tickets, 5 adult tickets and 12 student tickets. This will be:
5a + 12s = 160
We combine both equations
10a + 11s = 190 .......... equation i
5a + 12s = 160 ........... equation ii
Multiply equation i by 5
Multiply equation ii by 10
50a + 55s = 950 ....... equation iii
50a + 120s= 1600 ........ equation iv
Subtract equation iv from iii
50a + 55s = 950
- 50a + 120s= 1600
-65s = -650
65s= 650
Divide both side by 65
s = 10
The price for the student's ticket is $10.
You know that the computer technician has a flat 65 dollar service charge. This will be added to the hours worked.
hours= h
40 dollars per hour. So, every hour worked is worth 40 dollars.
c(h)= 40h+65
If you input the number of hours he worked as h, you would have the total amount of money he made if you solved the expression.
I hope this helps!
