Answer:

Value of given expression \frac{2p}{q}  when p = -4 and q = 2  is -4.

Step-by-step explanation:

Given expression , \frac{2p}{q}

We have to evaluate the value of the expression when p = -4 and q = 2

Consider the expression given \frac{2p}{q}

To find the value a the given value just put the values in the  given expression

 \frac{2p}{q} becomes  \frac{2(-4)}{2}

Solve further to get its value,

\Rightarrow \frac{-8}{2}

\Rightarrow -4

Thus, value of given expression \frac{2p}{q}  when p = -4 and q = 2  is -4.

\frac{x}{5}= \frac{2}{3}  = \frac{5}{y}
Break the equation into parts;
\frac{x}{5} = \frac{2}{3} ;  \frac{2}{3}= \frac{5}{y}
Solving for x;
\frac{x}{5} = \frac{2}{3}
x=\frac{10}{3}
Solving for y;
\frac{2}{3} = \frac{5}{y} &#10;y= \frac{3*5}{2} &#10;y= \frac{15}{2}
\frac{x}{y} = \frac{10/3}{15/2}
\frac{x}{y} = \frac{4}{15}

Answer:

  (a)  26 units

Step-by-step explanation:

The left-side vertical line extends from y = -3 to y = +3, so is 3-(-3) = 6 units long.

The bottom side horizontal line extends from x = -5 to x = 2, so is 2 -(-5) - 7 units long.

The sum of these two sides is 6 + 7 = 13 units. These two sides make up half of the perimeter, which is the total length of all four sides.

The perimeter is 2 × 13 units = 26 units.
