Oliver listens to 16 minutes of an audiobook every day during his commute to work. Let d represent the number of days commuting to work and m represent the total number of minutes Oliver listens to the audiobook while commuting.

Answers

We know that Oliver listens to 16 minutes of the audiobook every day during his commute to work. So, the equation would be m = 16d.

Write an expression for the total cost, in pounds, of: X jumpers at £15 each and y shirts at £12 each

Answers

x jumpers at £15 each. Total = 15*x = £15x

y shirts at £12 each. Total = 12*y = £12y

Total cost = £15x + £12y

Total cost = £(15x + 12y)

Final answer:

The total cost, in pounds, for X jumpers at £15 each and Y shirts at £12 each can be written as the mathematical expression: 15X + 12Y, where X and Y are the quantities of jumpers and shirts respectively.

Explanation:

To write an expression for the total cost of X jumpers at £15 each and Y shirts at £12 each in pounds, you need to multiply the cost per item by the quantity of each items and then add these two products together.

So, the total cost can be given as:

15X + 12Y

where

X represents the number of jumpers
Y represents the number of shirts

In this expression, '15X' stands for the total cost of the jumpers and '12Y' stands for the total cost of the shirts.

X=

Answers

♥ Answer: x=-6.9

Solve:
You need to Simplify both sides of the equation.
$806.265=-116.85x$
Now: Flip the equation.
$-116.85x=806.265$
Lastly Divide both sides by -116.85.
$(-116.85x)/(-116.85) = (806.265)/(-116.85)$

Final answer: x=-6.9
