We are given with the expressions A as 2/3x + 3/5y = 12 and B as 5/2y - 3x = 6. To eliminate y, we should multiply each function with a number that when the two functions are added, y cancels out. In this case, we multiply A by 5/3 and B by -2/5. Hence the answer is D. <span>D. 5/3A - 2/5B</span>
Answer:
h = 77
Step-by-step explanation:
From the problem, we are given that the number of square tiles in a crate is = s.
Also, the number of hexagonal tiles in the same crate = h
We can set up an equation to represent the relationship between the square and hexagonal tiles.
Because there are 68 more hexagonal tiles than square tiles in each crate, we can represent h:
When s = 9, we can easily find the value of h by replacing s with 9 in the above equation.
Answer:
A
Step-by-step explanation:
on the left of the equation, (6^4)^-5 = 6^-20
the right side you add the exponents so it would be (-7-3) =-10
so it would be 6^-10, which is greater than 6^-20
