(13+6)+4
19+4
The answer is 23
12x + 12 + 15 + 3x + 18 = 180
15x + 45 = 180
15x = 180 - 45
15x = 135
x = 135/15
x = 9
m < A = 12x + 12 = 12(9) + 12 = 108 + 12 = 120....A is 120
m < C = 3x + 18 = 3(9) + 18 = 27 + 18 = 45....C is 45
The answer is g (x) = (1/2) ^x-9 + 5
Just took the test and got an 80% :)
Since, an inch is to 3 feet, the length would be 18 feet and the width would be 12. To get the area, multiply length and width. The product would be 216 square feet. If a square foot costs $5, 216 square foot multiplied to $5 would be $1080 which is the cost to carpet the room.
It is best to use the discount first because the more value, higher percent.
Discount First:
4.00*.5 = $2.00 TOTAL
$2.00-$1.00 = $1.00 GRAND TOTAL
Discount After:
4.00-1 = $3.00 TOTAL
3*.5 = $1.50 GRAND TOTAL
You would save 50 cents
