The complement of 25% is 52% true or false

False

Step-by-step explanation:

Complementary Percentages gives 100% after adding, where 100% represents the Grand Total amount.

Let x  be the complement percentage of 25 %,

Thus, by the above statement,

x + 25 % = 100 %

x = 100 % - 25 % = 75 %

So, the complement of 25 % is 75 %,

Hence, this is a false statement that the complement of 25% is 52% .

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
