Bailey is thinking of a number. When
this number is multiplied by 4 and
increased by 13, the result is 8 less
than half of the number. What is
Bailey's number?

X represents the number

4x+13=(1/2)x-8 this is the equation

4x-(1/2)x=(-8)-13 combine like terms

(3 1/2)x=-21 simplify!

(7/2)x=-21 convert 3 1/2 into a fraction

x=(-21)(2/7) multiply both sides by 2/7 in order to isolate x

The answer is X= -6

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,

step-by-step explanation:

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
