Answer:

12.124-3\sqrt{22}

Step-by-step explanation:

\sqrt{75} = \sqrt{5^{2}*3} \\

\sqrt{48}= \sqrt{2^{2}*2^{2}*3} \\

\sqrt{198} =\sqrt{3^{2}*2*11} \\

\sqrt{75} +\frac{1}{2} *\sqrt{48} - \sqrt{198} \\\\\sqrt{5^{2}*3} +\frac{1}{2} *\sqrt{2^{2}*2^{2}*3} - \sqrt{3^{2}*2*11} \\\\5\sqrt{3} +\frac{1}{2} *4 \sqrt{3} - 3 \sqrt{2*11} \\\\5\sqrt{3} +2 \sqrt{3} - 3 \sqrt{22} \\\\5*1.732 +2*1.732 - 3 \sqrt{22} \\\\8.66 + 3.464 - 3 \sqrt{22}\\\\12.124- 3 \sqrt{22}

Hello!

We can solve this by using substitution

we can plug y = x - 1 into the other equation

So 2x - 3( x - 1) = -1

We can distribute the -3 to (x - 1)

2x - 3x + 3 = -1

Combine like terms

-x + 3 = -1

Subtract 3 from both sides

-x = -4

Since x is negative we can multiply both sides by -1

x = 4

We can plug x into the first equation

y = (4) - 1

y = 3

The answers are x = 4 and y = 3

Hope this helps!

Answer:

-1 1/2 and -1 3/4 on the number line.

Step-by-step explanation:

First you find -1 on the number line. Then you add 1/2 which is also 2/4. You find it by going two places from -1 to the right.

Then you do the same for -1 3/4. You start at -1 and move 3 places to the right.
