Answer:
x=-6,11
Step-by-step explanation:
Break down the problem into these 2 equations.
2x-5=17
-(2x-5)=17
2 Solve the 1st equation: 2x-5=17
x=11
3 Solve the 2nd equation: -(2x-5)=17
x=-6x
4 Collect all solutions.
x=-6,11
Answer:
x = -7
Step-by-step explanation:
( 5 x − 15 ) 2 = − 100

Answer: No, She is not right.
Step-by-step explanation:
First question:
Initial number of bison = 550
After increasing 10% than the initial number of bison, the new number of bison after one year= Initial number of bison + 10 % of the initial number of bison
=
=
=
=
=
Second question:
Let Initial number of bison = x
After decreasing 10% than the initial number of bison, the new number of bison after one year= Initial number of bison - 10 % f the initial number of bison
=
=
=
=
According to the question,
Since, 605 ≠ 611
Therefore, Both questions have different answer.
⇒ Noah is not correct.
