With what????????????????????
Answer:
a.) 10 months
b.) Kool Karate
c.) Karate Klub
Step-by-step explanation:
Karate Klub : y=25x+200
Kool Karate : y=35x+100
A.) First, set the equations equal to each other then solve for x. 
take away 100 from both sides

take away 25x from both sides

divide 10 from both sides so x can be by itself and equal to 1

This means that at 10 months, the cost is the same for both.
B.) Substitute 6 for x in both equations
Karate Klub : 
Kool Karate :
The cost for Kool Karate is cheaper, so that is what he should join.
C.) Substitute 12 for x in both equations.
x=12 because there are 12 months in a year.
Karate Klub:
Kool Karate:
The cost for Karate Klub is cheaper, so that is what he should join.
Answer:
I think the answer would be C
"The correct equation is s+26=42"
Step-by-step explanation:
You would have to take whatever number s represents and add it by 26 to get 42, so the correct equation would be s+26=42 because you have to take whatever number s is and add it by 26 to get the answer.
The answer is 32. all you have to do is plug in the numbers for what the letters say they indicate so r=4 so you would plug in 4 where the r is and then plus 6 where the b is and then because b and d are right next to each other, that means you need to multiply so plug in 5 for d and then multiply those together, your equation should end up looking like this
√4 + 6(5)
