Hi!

Solve this using PEMDAS.

Parentheses - addition

\frac{1}{2} - 3 (1\frac{1}{2})^{2}

Exponents

\frac{1}{2} - 3 * 2\frac{1}{4}

Multiplication

\frac{1}{2} - \frac{27}{4}

Subtraction

-\frac{25}{4}

The answer is -\frac{25}{4} or -6\frac{1}{4}

Hope this helps! :)

Angles in a triangle add up to 180
set the three measurements equal to 180 and solve for x

x + x + 46 = 180
2x + 46 = 180
2x = 134
x = 67

Write a system of linear equations that has the ordered pair as its solution (3,5)
ololo11 [35]
An easy way to do this is by using the simplest equations you can:

x + y and x - y

(3, 5) is (x, y). all you have to do is plug those into your equations and get a result, so:

x + y = 8
(because 3 + 5 = 8)
x - y = -2
(because 3 - 5 = -2)

and those can serve as your system of equations. 

you can check it by solving by substitution:
x - y = -2
x + y = 8

solve one of the equations for a single variable:
x = y - 2

plug it into the second equation:
(y - 2) + y = 8
y - 2 + y = 8
2y - 2 = 8
2y = 10
y = 5

then plug that result back into the equation:
x + y = 8
x + 5 = 8
x = 3
