Answer:
D. 4r + 3(10 – r) = 37
Explanation:
Let r be the roller coaster ride. Since it costs 4 tickets, this gives us the expression 4r.
We know that there were 10 rides total; this leaves Michael 10-r for the number of times he rode the boat ride.
Each boat ride costs 3 tickets; this gives us the expression
3(10-r)
Together, this gives us
4r+3(10-r) = 37

Step-by-step explanation:
Answer:
Yes if the voltage is kept constant
Step-by-step explanation:
V=IR
Difference of 2 perfect squares
a^2-b^2=(a-b)(a+b)
25=5^2
x^2-5^2=(x-5)(x+5)=0
set to zero
x-5=0
x=5
x+5=0
x=-5
x=5 or -5
A
8(hours)-5=67
8(h)-5=67
8h-5=67
8h=67+5
8h=72
H=72/8
h=9
