Answer:

$16.80

Step-by-step explanation:

20 % of 20 is 4 and you would take the 4 off for a discount. 5% of 16 is 0.8 and you would add it since it's an additional tax.

Which 2 colours are the ones for this?
Sav [38]

Answer:

Step-by-step explanation:

red and green

you know this because the red line has an X intercept at 1.5,0 which can be seen on the graph, as well as a Y intercept of 0,-3 which means that 2x-3 is represented by the red line

the green line passes through 0.8, 0 for its x intercept and 4,0 for its y intercept which is also seen on the graph by the green line.

to prove this, set each equation equal to zero and solve-

so 2x-3=0

2x=3

x=1.5

4-5x=0

-5x=-4

x=0.8

also the whole number in each equation (-3 and the 4) are y intercepts since when x is zero they are themselves

How to solve for y and simplify
Dmitry_Shevchenko [17]

Answer:

y = \frac{2}{5}

Step-by-step explanation:

Given

- 3y = - \frac{6}{5}

Multiply both sides by 5 to eliminate the fraction

- 15y = - 6 ( divide both sides by - 15 )

y = \frac{-6}{-15} = \frac{6}{15} = \frac{2}{5}

What is the mathematical reasoning for Step 3?
Colt1911 [192]

Based on the operation in step 3, the mathematical reasoning that we see is the Associative property.

<h3 /><h3>What is the reasoning in step 3?</h3>

Step 2 was:

= 3/4x (-8x) + (3/4x) (6)

Step 3 then became:

3/4 x (-8) × x × x  + 3/4 x 6x

This shows the associative property because the numbers were regrouped but because they are being multiplied by each other, the result will not change.

Find out more on the associative property at brainly.com/question/13181.
