Use PEMDAS:

P Parentheses first

E Exponents (ie Powers and Square Roots, etc.)

MD Multiplication and Division (left-to-right)

AS Addition and Subtraction (left-to-right)

[(30 + 6) - 32] : 9 · 2 = (36 - 32) : 9 · 2 = 4 : 9 · 2 = 4/9 · 2 = 8/9

Evaluate the following expressions for a = -3,b=2,c=5
Ksju [112]

Hey!

----------------------------------------------------------------------

We know that (a = -3), (b = 2), (c = 5), and (d = -4).

----------------------------------------------------------------------

Solution #1:

=\frac{a-4b}{3c+2d}

=\frac{(-3) - 4(2)}{3(5) + 2(-4)}

=\frac{(-3) - 8}{15 +( -8)}

=\frac{-11}{7}

≈ 1.57

----------------------------------------------------------------------

Solution #2:

= a - 4b / 3c + 2d

= (-3) - 4(2) / 3(5) + 2(-4)

= (-3) - 8 / 15 + (-8)

= (-3) - 0.53 + (-8)

= (-3.53) + (-8)

= -11.53

----------------------------------------------------------------------

Solution #1 Answer: 1.57

Solution #2 Answer: -11.53

----------------------------------------------------------------------
