Hi there!  

»»————- ★ ————-««

I believe your answer is:  

{x=152.666....

»»————- ★ ————-««  

Here’s why:

⸻⸻⸻⸻

\boxed{\text{Solving for x...}}\\\\3x+ 65= 523\\----------\\\rightarrow 3x + 65 - 65=523-65\\\\\rightarrow 3x = 458\\\\\rightarrow\frac{3x = 458}{3}\\\\\rightarrow  \boxed{x=152.666....}

⸻⸻⸻⸻

»»————- ★ ————-««  

Hope this helps you. I apologize if it’s incorrect.

The total distance to be covered was 52 miles. If he cycled at a constant rate of 13 miles per hour, how much time did Ricky tak
QveST [7]
13 miles per hour means he will cover 13 miles in 1 hour.

therefore in 2 hours, 26 miles.    3 hours, 39 miles.  4 hours, 52 miles.

Or time = distance/speed

time = 52/13 = 4 hours

Solve the system of equations 4x + 3y = -25 <br><br> 7x - 3y = -52
SIZIF [17.4K]

Answer:

x = -7

y = 1

Step-by-step explanation:

Solve by Substitution :

// Solve equation [2] for the variable x

[2] 7x = 3y - 52

[2] x = 3y/7 - 52/7

// Plug this in for variable x in equation [1]

[1] 4•(3y/7-52/7) + 3y = -25

[1] 33y/7 = 33/7

[1] 33y = 33

// Solve equation [1] for the variable y

[1] 33y = 33

[1] y = 1

// By now we know this much :

x = 3y/7-52/7

y = 1

// Use the y value to solve for x

x = (3/7)(1)-52/7 = -7

Solution :

{x,y} = {-7,1}
