Answer:
No solution
Step-by-step explanation:
3x + 5 - x = 2(x-1)-4
2x + 5 = 2x - 2 - 4 Add the like terms. Distribute the 2.
2x = 2x - 6 - 5 Subtract 5, add like terms
2x = 2x - 11 Add like terms
0 ≠ -11 Subtract 2x to keep variables on one side
Since zero does not equal -11, there are no solutions
Answer:
1. Yes
2. No
Step-by-step explanation:
You can have a case such as 26,30,30,30,30 and another case : of 4,40,40,32,8 satisfying the 2 statements at the same time but in the 2nd case, the average that is less than 28.
From the given statements combined together, to get e-a=4. So once you get this information, you can have a big range of values that may or may not have average >28.
D (56.5)
Originally, the train traveled 340 miles in 8 hours
If we use the formula d/t, we'll have 340/8, which is 42.5
If we add 14, then we'll have 56.5, or d
Slope intercept form is y = mx + b
7 tickets for $5 means that 1 ticket costs 5/7 dollars
So for part a, the slope intercept form would be:

where x is the number of tickets, and y is the price.
For part b)
The slope intercept form is:

where x is the number of all you can ride wristbands you buy, and y is the total price.
Answer: x is 52 and y is 38.
Step-by-step explanation:
x+128=180
x=52
52+y=90
y=38
