Answer:
1) 102
2) 62
Step-by-step explanation:
12 + 5 + 3² × 10 - 5
12 + 5 + 9 × 10 - 5
12 + 5 + 90 - 5
17 + 90 - 5
107 - 5
102
(12+5) + 3² × (10 - 5)
(17) + 9 × (5)
17 + 45
62
The first choice is right, area of 1 is 20, area of 2 is 16

Answer:
y=-1/2x+5
x=-2y+10
Step-by-step explanation:
Find the negative reciprocal of the slope of the original line and use the point-slope formula
y
−
y
1
=
m
(
x
−
x1
)
to find the line perpendicular to y
=
2
x+
2.
To solve for x you -5 from both sides to get y-5=-1/2x then multiply both sides by -2 to get -2y+10=x which is the same as x=-2+10
Answer:
Discount % = (Discount/List Price) × 100
Step-by-step explanation:
To calculate the discount, you must have the list price (marked price) and the selling price of the product you are buying.
Example: If the list price of a book is $50, and $10 discount is offered on the book, then the discount percentage is calculated as follows.
Discount % = (Discount/List Price) × 100
List price = $50; discount = $10
Discount (%) = (10/50) × 100
= 100/5
= 20%
