Answer:

nope

Step-by-step explanation:

A-(b-c)=(A-b)-c

let a be 2, b be 3 and c be 4

2-(3-4)=(2-3)-4

2-(-1)=(-1)-4

2+1=-1-4

3=-5

therefore, association is not goot under subtraction

Find the markup and the selling price of the following item. Round answers to the nearest cent. A chemistry set costing $27.50,

postnew [5]

Let x be marked up price. We have been given that a chemistry set costing $27.50, marked up 32% on cost.

$x=27.50\times\frac{32}{100}$

$x=27.50\times.32$

$x=8.8$

Therefore, mark up price is $8.80.

Since we know that selling price of any item equals the sum of cost and mark-up price of the item.

Let us find selling price of our chemistry set.

$\text{Selling price of chemistry set}=27.50+8.8$

$\text{Selling price of chemistry set}=36.30$

Therefore, the selling price of the chemistry set is $ 36.30.

Solve the system using any method. x= - 4y+7 -2y+3x=9

Arte-miy333 [17]

The solution to the given system of equation is (25/7, 6/7)

<h3>System of equation</h3>

Given the system of equation expressed as:

x= - 4y+7 ........... 1

-2y+3x=9 ...........2

Substitute the equation 1 into 2 into have:

-2y + 3(-4y+7) = 9

-2y + 3(-4y) + 3(7) = 9

-2y - 12y + 21 = 9

Collect the like terms

-14y = 9- 21

-14y = -12

y = 6/7

Substitute y = 6/7 into equation 1;

x =-4y + 7

x = -4(6/7) + 7

x= -24/7 + 7

x = -24+49/7

x = 25/7

Hence the solution to the given system of equation is (25/7, 6/7)
