Answer:
b-108y³/x²
Step-by-step explanation:
4x^-2/(3y)^-3
negative exponent in nominator , moves to denominator and becaomes positive , and vice versa
4(3y)³/x²=4(27y³)/x²
108y³/x²
Answer:
an inequality
Step-by-step explanation:
An inequality is the relation between two expressions that are not equal. The symbols generally used are less than (<) or greater than (>), as in:
4 > 3 or 4 < 9
That means that each side of the symbol represents a value that is different from the other side. The relationship is described with the sign to indicate which side has a greater value.
If both sides have an equal value, then it's an equation.
Answer:
The player answer correctly 30 questions
Step-by-step explanation:
First we have to develop the information that gives us as 2 equations
x = correct answer
y = incorrect answer
z = score = 40
h = total answer = 50
2x - y = z x + y = h
2x - y = 40 x + y = 50
we clear the x of one equation and replace the value of x in the other equation
x = 50 - y
2x - y = 40
2(50 - y) - y = 40
100 - 2y - y = 40
-3y = 40 -100
y = -60/-3
y = 20
x = 50 - y
x = 50 - 20
x = 30
