Answer:
Option b 18x-8 is correct answer.
Step-by-step explanation:
We need to simplify the expression 4(3x – 2) + 6x(2 – 1) and find the result.
Solving:
= 4(3x – 2) + 6x(2 – 1)
Multiplying terms with values in the bracket.
= 12x - 8 + 12x -6x
Adding like terms
= 12x + 12x - 6x -8
= 24x -6x -8
= 18x -8
So, Option b 18x-8 is correct answer.

Step-by-step explanation:
I think your question isn't well written and that 234 was meant to be 2.34 and 112 was meant to be 1.12
Let the amount spent on tomatoes be x.
The information given in the question can then be used to form an equation as thus:
Apples + Peaches + Tomatoes = $9.63
(2.34 × $1.32) + (1.12 × $1.20) + x = $9.63
$3.0888 + $1.344 + x = $9.63
x = $9.63 - ($3.0888 + $1.344)
x = $9.63 - $4.4328
x = $5.1972
The amount spent on tomatoes will be $5.1972
To model half-life, use the formula

is the amount that you start with.
is the half-life. You plug in 50 for
