PLEASE HELP! A) 6,135º C B) 6,681º C C) 502º C D) 47º C
Arada [10]

Answer: 47°C

Step-by-step explanation:

Since we are given the velocity, all we have to do is plug in 358 for v and solve for t.

358=20\sqrt{273+t}                    [divide both sides by 20]

17.9=\sqrt{273+t}                        [square both sides to cancel out square root]

320.41=273+t                       [subtract both sides by 273]

t=47.41

Now that we know the temperature is 47.41°C, we know our answer choice is D.

Solve for x: 4x(3y-2)=7x+11
kupik [55]

Answer:

x=11(12y-15)

Step-by-step explanation:

4x(3y-2)=7x+11

12xy-8x=7x+11

12xy-8x-7x=11

12xy-15x=11

x(12y-15)=11

x(12y-15)/(12y-15)=11/(12y-15)

x=11/(12y-15)
