What is 3x+5-x=2(x-1)-4
Romashka-Z-Leto [24]

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

A.) write an equation in slope intercept form for the total cost of any number of tickets at 7 tickets for $5.
MrMuchimi
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:

y = \frac{5}{7}x

where x is the number of tickets, and y is the price.

For part b)

The slope intercept form is:
y = 25x

where x is the number of all you can ride wristbands you buy, and y is the total price.
