Lets say a fork costs x $. Therefore a spoon costs 2x $.
2x + x = 6. => 3x = 6. => x=2
so:
a) A spoon costs: 2x = 2 × 2 = $4
b) (12 × 4) + (10 × 2) = $68
Answer:
Step-by-step explanation:
As per graph it is visible that the slope is negative, it goes down when x-value increases
<u>Use two points to find the slope:</u>
<u>Slope formula:</u>
<u>Value of the slope:</u>
- m = (-3 - (-1))/(0 - (-4)) = -2/4 = -1/2

I couldn't answer on your most recent question so here :) Good luck
Simply find the average of the entire bunch of numbers.
Then you can go down the list, and easily spot which ones
are smaller than the average and which ones are larger.
To find the average of a bunch of numbers:
-- Add up all of the numbers in the bunch.
-- Divide the sum by how many numbers there are in the bunch.
