Answer:
(6, 9)
Step-by-step explanation:
Plug in 2/3x + 5 as y into 7x - 3y = 15
7x - 3(2/3x + 5) = 15
7x - 2x - 15 = 15
Add like terms:
5x - 15 = 15
5x = 30
x = 6
Then, plug in 6 as x into y = 2/3x + 5 to solve for y:
y = 2/3x + 5
y = 2/3(6) + 5
y = 9
So, the solution to the system of equations is (6, 9)
All cubes are similar because every one of them have an equal width and length and height.
I really hope I helped
The answer is 5 i believe lol
