Answer: The apple costs 0.45
Step-by-step explanation: Oranges will be x in our equations and Apples will be y.
Anna's equation is: 3x + 6y = 4.5 (1)
Maria's equation is: 2x + 2y = 2.1 (2)
As we need to find y, we need to cancel x, this way, we multiply equation (1) by 2 and equation (2) by 3.
3x + 6y = 4.5 (x2)
2x + 2y = 2.1 (x3)
__________________
6x + 12y = 9
6x + 6y = 6.3
__________________
Now, we subtract them
6x + 12y = 9
-6x - 6y = -6.3
________________
6y = 2.7 → y = 2.7/6 → y = 0.45
Step-by-step explanation:
log(7x³/z) = log(7) + log(x³) - log(z).
3log(5) + 2log(x) - log(25) = log(125) + log(x²) - log(25) = log(125x²/25) = log(5x²).

Answer:
C. 72 sorry if its wrong
Step-by-step explanation:
trapezoid formula : A= 1/2h(B+b)
plug in:
A= 1/2×6(10+14)
A= 3(24)
A= 72
