8. Square root of 100, 41/3, 14
9. 0.6, 2/3, Square root of 9/16
Answer:
$1600
Step-by-step explanation:
The $800 that the customer paid is 50% of the retail price, so the retail price is twice that amount:
$800/0.50 = $1600
The selling price of the mattress before the discount was $1600.

The wholesale price was $1600/2.25 = $711.11
5a+3b
5(2)+3(4)
10+12
22
(5+a)(3+b)
(5+2)(3+4)
(7)(7)

The order of the steps differ for the two expressions because for the first expression, you multiply 5a and 3b first. Then, you add them together. However, for the second expression, you add what's inside the parenthesis first then multiply them. So, the order of the steps is the opposite of the other expression.
In case of plane, for y intercept, x and z are o .
So we will get
4(0)+5y-0=20
5y=20
Dividing both sides by 5
y = 4
So the y intercept is (0,4,0).
In second question, x intercept is 1, y intercept is -1 and z intercept is 2 .
So the correct option is the third equation , that is x-y+2z=4 .
