x+y=19 and 6.5x+3y=74.5 can be used to determine the number of gifts wrapped and number of giftbags prepared where x represents the wrapped gifts and y represents giftbags.
Step-by-step explanation:
Let,
x be the gift wrapped with wrapping paper.
y be the gifts in gift bag.
Time for wrapping one gift = 6.5 minutes
Time for doing 1 gift bag = 3 minutes
Total gifts = 19
Total time = 74.5 minutes
According to given statement;
x+y=19
6.5x+3y=74.5
x+y=19 and 6.5x+3y=74.5 can be used to determine the number of gifts wrapped and number of giftbags prepared where x represents the wrapped gifts and y represents giftbags.

Answer:
220ft^2
Step-by-step explanation:
In red: 12ft - 10ft = 2ft and there 2 sides so 2ft / 2 = 1ft
In blue: 18ft - 12ft = 6ft
The missing area in dark blue: 6ft x 1ft = 6 / 2 = 3
total rectangle area: 12ft x 18ft = 216
216 - (3 + 3) = 216 - 6 = 200 subtract 6, we added that area in
Answer:
Step-by-step explanation:
m∠AOC = 180 as it is straight line
m∠AOC = m∠AOB + m∠BOC
m∠AOB + m∠BOC = 180
3x + 124 + 6x + 29 = 180
9x + 153 = 180
9x = 180 - 153
9x = 27
x = 27/9
x = 3
m∠BOC = 6x +29 = 6*3 + 29 = 18 +29 = 47
Answer:
x⁴ - 8x² + 9
Step-by-step explanation:
The Area of the smallest square is A1 = x . x = x²
The Area of the second square is A2 = ( x² - 3 )(x² - 3)
A2 = x⁴ - 3x² - 3x² + 9
A2 = x⁴ - 6x² + 9
The Area of the Shaded shape is A2 - A1
x⁴ - 6x² + 9 - x²
x⁴ - 8x² + 9
