You would divide -204 divide it by -17 and you would get 12
X=12
I think that the answer is 3Y+30. I hope this helps!!! :)
For #1 it's going to be proper because it's pretty specific, and for number two it's going to be all common because it's not citing anything specific.
X^2 - x - 90 =0
This equation is in standard form ax^2+ bx + c
The sum of the solutions is -b/a (a and b are the coefficients from the equation above, not the solutions to the equation)
The answer is 1/1 = 1
Answer:
z = 1 i hope this helps! :)
Step-by-step explanation:
given 12 = 15(z - 1/5)
distribute the 15 to both the z and the - 1/5
12 = 15z - 3
add 3 to both sides
15 = 15z
divide both sides by 15
1 = z
flip the equation around so the variable is on the left
z = 1
