3^2+6^2=c^2
9+36=c^2
45=c^2
c=3 sqrt5
Answer:
t+3r
Step-by-step explanation:
This is a one step solution
All you do is add like terms
In this case the only like terms are the varibles r
2r+(t+r)
so if you add all of the rs together there would be 3rs
So the rest of the problem would continue as normal while bringing the 3r to the end
t+3r
For 1 multiply both sides by 3 which gives you 3y-y=12. Then combine like terms 2y=12. Lastly divide both sides by 2 and you get y=6. And for 3 first multiply both sides by 4 which gives you 6y-32=y+8. After that combine like terms 6y-y-32=8. Now add the equation together 5y=40 and then divide by 5 and get y=8
Answer: x=4
Step-by-step explanation:
-8-x=x-4x
-8-x=-3x
-8=-2x
x=4
Drew has 56 Red Marbles, 56 Green Marbles, Drew has about 60 Blue Marbles. First i added 6 to Red since Red Has 6 More Marbles Than Blue, Then i added Subtracted 4 from green, which resulted in 46 Green Marbles. Finally i added 4 and 6 to get 60 Blue Marbles. I am not sure if i am correct, but i gave it a shot! ^-^
