<span>|5x − 6| = −41 it has no solutions because module ( abs value) cannot be negative
|7x + 13| = 27 -(7x+13)=27
7x+13=27 -7x-13=27
7x=14 -7x=40
x=2 x=-40/7
check: </span>|7*(-40/7) + 13| = 27 , |-40 + 13| = 27, |-27| = 27 correct<span>

Answer:
x = (-150)/49
Step-by-step explanation:
Solve for x:
49 x + 150 = 0
Hint: | Isolate terms with x to the left hand side.
Subtract 150 from both sides:
49 x + (150 - 150) = -150
Hint: | Look for the difference of two identical terms.
150 - 150 = 0:
49 x = -150
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 49 x = -150 by 49:
(49 x)/49 = (-150)/49
Hint: | Any nonzero number divided by itself is one.
49/49 = 1:
Answer: x = (-150)/49
Answer:
To break even, Liza must answer 2 questions correctly to give her 6 points, because she now has negative 6 points a the result would be a score of 0
Step-by-step explanation
multiply negative 2 by the 3 incorrect questions, and you get negative 6.
divide 6 by 3 to get 2 to find the number of questions she needs to make correct to break even.
(b)+(b+45)=215
b = # of boys
there are 45 more girls than boys and 215 students total.
minus 45 on both sides leaving you with
(b)+(b)=170
combine like terms leaving you with
2b=170
divide both sides by 2
b=85
there were 85 boys
85+45=130
(the 45 for the # of girls more than boys)
there were 130 girls.
