Answer:
Step-by-step explanation:
(A) Definition of Supplementary angles
(B) Distributive property
(C) Transitive property
(D) Reflexcive property
(E) Division property of equality
It would still be 7:2 because when tripled, you triple both numbers, so you get 21: 6, which is the same thing as 7:2, but you just use more. And for ratios, they usually want them to be in simplest form, so it is d) 7:2. The ratio does not change when you triple both sides.
Y=-5x-19
Y=5x +1
Y=-18
-18=5x+1
-19=5x
X= 3.8
Might be wrong
For this case we propose a rule of three to obtain the number that represents 25% of 37.
So, we have:
37 --------> 100%
x -----------> 25%
Where "x" is the number that represents 25% of 37.

Finally, we have that 25% of 37 is 9.25.
Answer:
25% of 37 is 9.25.
Answer:
-4 and 5
Step-by-step explanation:
4*5 = x(x-1) ; cross multiply
20 = x²-x ; distribute multiplication over subtraction
x²-x-20 =0; subtract 20 from both sides
(x+4) (x-5) = 0; factor
x+4 =0 gives x = -4
x-5 =0 gives x = 5
