Answer:
child's is $14
adult is $23
Step-by-step explanation:
3c + 1a = 65
3c + 3a = 111
a = 65-3c
3c + 3(65-3c) = 111
3c + 195 -9c = 111
-6c = -84
c = 14
3(14) + a = 65
42 + a = 65
a = 23
I love prime factorizations! 50= 2 x 5 x 5 or 2 x 5 at the power of 2
The chips all together are 2.67, the candy bars total 2.5, the soda bottle is 1.89$. Add that all together for a total of 7.06. Multiply that by 1.08 to account for taxes and get 7.62.
Answer:
Step-by-step explanation:
25x2 − 40x + 16 = (5x)² - 2*5*4 + 4² { (a - b)² = a² - 2ab + b² }
= (5x - 4)² { here a = 50 and b = 4}
Side of the square = 5x - 4 units
Part B:
25x2 − 16y2 = (5x)² - (4y)² { a² - b² = (a + b) * (a - b) }
= (5x + 4y) * (5x - 4y) { here a = 5x and b = 4y}
Dimensions of Rectangle: (5x + 4y) ; (5x - 4y)
