Answer:

10x + 5y - 15z

Step-by-step explanation:

5(2x + y - 3z)

To get the equivalent expression we apply distributive property

a(x+b)= ax+ab

Using distributive property we distribute the number inside the parenthesis  Distribute 5 inside the parenthesis

5 times 2x becomes 10x

5 times y becomes 5y

5 times -3z becomes -15z

5(2x + y - 3z)

10x + 5y - 15z

Lena [83]

Answer:

The candidate should get 5829 votes.

Step-by-step explanation:

This is a proportion question. The ratio should hold for both the pole and the actual vote.

Equation

x /9570 = 67/110          Multiply both sides by 9570

x = 67 * 9570 / 110       Multiply the two numerators.

x = 641190 / 110            Divide by 110

x = 5829

the two shorter sides in a right triangle have the same length . the area of the right triangle is 7.36 square meters. what is t
harina [27]

The length of the hypotenuse is 5.426 meter

Let the two shorter sides of the right angles triangle be denoted as x meters.

The formula for the area of right triangle is given as,

                     A = ab/2

  Where, a and b are the length of the shorter sides of the triangle

Also we have been given the area of the triangle which is 7.36 sq. meter

Thus ,    A = 7.36

             x^2/2 = 7.36

              x^2 = 14.72

                x = 3.84

Now according to the Pythagoras theorem,

   H = √P^2 + B^2

Where,  H = hypotenuse

               P = perpendicular

              B = base

Now putting the required values we get

    H = √x^2 + x^2

        = √2x^2

        = x√2

       = 5.426 meter

Hence the length of the hypotenuse is 5.426 meter
