Answer:
On sale at a deficit of -20% from the original price is saying that the item is at 80% of its original value.
Converting percentages using decimals is a very easy way to fine original values.
So:
$76.80 = 80% of the original value
convert the 80% into a decimal = 0.80
The maths:
$76.80 ÷ 0.8 = $96.00
$96.00 = the original value.
Answer:
5(x-3)+7=-45
Step-by-step explanation:
The only possibly way for 5 to multiply 2 numbers is if those numbers are in parenthesis
Option B is correct. The required expression on expansion of 20х-[2х -(х+2)-(6-x 2 )-(28 +x+x2] is 20x + 36
Expressions are function that does not include "equal" sign
Given the expression
20х-[2х -(х+2)-(6-x² )-(28 +x+x2]
Expand and collect the like terms
= 20х-[2х -х-2-6+x² -28 - x - x²]
= 20x - [x - 8 + x² - 28 - x - x² ]
x and x² cancels out from the expression to have
= 20x - [- 8 - 28]
= 20x -(-36)
= 20x + 36
Hence the required expression on expansion is 20x + 36
