Simplify the expression -3 ÷ (-2/5

7.5

Step-by-step explanation:

To solve this expression, we can use PEMDAS or order of operations.

Parenthesis

Exponents

Multiplication>Division (Depends on which comes first from left to right)

Addition>Subtraction (See Multiplication>Division)

So First, lets solve the Parenthesis. -2/5=-.4

So now, our equation is -3/-.4

There is no exponents or multiplication, so lets just Divide.

-3/-.4=7.5

The solution is 7.5

Hope this helps!

only 10/60 isn't equivalent

hope this : )

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
