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

kvv77 [185]

Answer:

1. $12

2. 3 boxes

3. 2 boxes

Step-by-step explanation:

1. You first need to find the dollar amount each of them sold. To do this, you need to find the lowest common multiple for 4 and 6. The lowest common multiple is 12.

2.  Kevin sells boxes of cookies for $4 each so, you need to find the value of  X in this equation: 4 . X = 12. The value of X is 3.

3. Laura sells boxes of cookies for $6 each so we need to find the value of X in this equation: 6 . X = 12. X = 2 because that is the only answer that makes since.
