Answer:

x = -4

Step-by-step explanation:

Square both sides:

(\sqrt{-5-2x})^2 =(\sqrt{-1-x} )^2

The square root and the square will cancel to leave simply the argument within the square root:

-5 - 2x = -1 - x

Now simply isolate the variable x:

x = -5 + 1 = -4

Check to see if x = -4 will work:

\sqrt{-5-2*(-4)} =\sqrt{-1-(-4)}

\sqrt{3} =\sqrt{3}

This works, so we know that x = -4 is a solution.

Hope this helps!

Omae wa sinderou nani (questions in the image btw)
Korvikt [17]

Let a be the number of hours worked at Job A and b the number of hours at Job B. Then

a+b=30

and

7.5a+8b=234.50

From the first equation,

b=30-a

and substituting this into the second gives

7.5a+8(30-a)=234.50\implies-0.5a+240=234.50

\implies0.5a=5.50

\implies\boxed{a=11}
