Answer:
$7.50
Step-by-step explanation:
Sara buys a sweater that costs $30
The store is having a 25% off sale.
To figure out what 25% is you do 25/100, which will give you 0.25,
Multiply 0.25 by $30
You should get $7.50.
Answer:
See below
Step-by-step explanation:
The formula for calculating percent is
% = (cost of item/total cost) × 100 %
% = (cost of item/1875) × 100 %
% = (cost of item/18.75) %
You can use the same formula to calculate the percent for each item in the budget. For example,
Housing: % = 420/18.75 = 22 %
You can do this for each budget item and get the table below.
Step-by-step explanation:
3(x + 1)(x + 7) − (2x + 5)²
3(x² + 8x + 7) − (4x² + 20x + 25)
3x² + 24x + 21 − 4x² − 20x − 25
-x² + 4x − 4
-(x² − 4x + 4)
-(x − 2)²
A squared number is never negative (provided x is a real number), so -(x − 2)² is never positive.
I think it’s y = 1x + 13.
