Aride on a roller coaster cost 4 tickets while the boat ride onlycost 3 tickets michael went on the two rides a total of ten times and spent a total of 37 tickets

One equation that represents this statement above me could be: 4r + 3 (10-r) = 37.

How? R = Rollercoaster - B = Boat Rides

r + b = 10 

37 tickets were spent so..

4*r + 3*b = 37

We just multiplied the number of rides on roller coasters and the boats with the price of both.

Now we have to express boat rides from the first equation:

b = 10-r, and express that in the second equation, now we get:

4r + 3(10-r) = 37, which is the answer.

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

0 = ( 2 - 4 ) ( p + q )0 = ( 2 - 4 ) ( 2 + 5 i ),   by multiplying these0 = ( 4 + 10 i - 8 - 20 i )0 = 4 - 8 + 10 i - 20 i0 = - 4 -10 i   0 = 2 ( - 2 - 5 i )0 / 2 = - 2 - 5 i- 2 - 5 i = 0- 5 i = 2i = 2 / - 5
