Answer:
x=6
Step-by-step explanation:
Since the line is vertical, it has no slope. This means that it will only go through points that have an x-coordinate of 6.
Answer:
The number of people on each bus is 32
Step-by-step explanation:
We are given
Total number of students =267
Total number of adults =21
So,
Total number of passengers = ( Total number of students)+(Total number of adults)
now, we can plug values
Total number of passengers =267+21
Total number of passengers =288
We are given
Number of buses=9
so,
Number of passengers on each bus = (total number of passengers)/( Number of buses)
now, we can plug values
Number of passengers on each bus is
So,
The number of people on each bus is 32
Answer: v = 25
Step-by-step explanation:
Divide each side by 3
3v/3 = v
75/3 = 25
v = 25
25 * 3 = 75
Answer:
195 mL of the 90% solution
Step-by-step explanation:
Let the number of mL of 90% mixture = x
Hence, our equation is
780mL × 15% + x mL × 90% = (780mL + x) 30%
117 + 0.9x = 234 + 0.3x
Collect like terms
0.9x - 0.3x = 234 - 117
0.6x = 117
x = 117/0.6
x = 195 mL
Therefore, You will need 195 mL of the 90% solution
18. 2(x + 26) = 264
x = $106
20. (9/5)C + 32 = F
(9/5)(-35) + 32 = F
-63 + 32 = -31 degrees F
22. 73 = 2x + 11, x = the original number of customers
x = 31 original customers
24. 8x + 19 = 115
x = 12 days
