Answer:
D.(1,1)
Step-by-step explanation:
Just plug in each pair of values in the multiple choice answers for x and y.
If we plug in (1,1)
The equation is
4(1) +5(1) ≤ 20
4+5≤ 20
9≤ 20
Since 9 is less than 20 we know statement is true, so we know (1,1) is a solution.
If we were to plug in any other choice like (0,5), the right side of the equation would be greater than 20 and the statement would not be true.
The answer that you need is C
The common denominator is 12
so
1/3 = 4/12
3/4 =9/12
M+C=152 This is the correct answer because the to variables added together makes 152
