3 minutes=39 meters
2 minutes= x meters

  3minutes      2minutes
_________ = ________
  39meters       x meters

Cross multiply
3x=78
divide both sides by 3
x=26


1m=1000mm
So 26*1000=26000mm

Answer=26000mm

Solve for w.<br> 8(w+2) = 40
AleksAgata [21]

Answer:

  w = 3

Step-by-step explanation:

 8 • (w + 2) -  40  = 0

Pulling out like terms :

3.1     Pull out like factors :

  8w - 24  =   8 • (w - 3)

Equation at the end of step  3  :

 8 • (w - 3)  = 0

Step  4  :

Equations which are never true :

4.1      Solve :    8   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2      Solve  :    w-3 = 0

Add  3  to both sides of the equation :

                     w = 3

One solution was found :

                  w = 3

Which number line represents the solution of 4 - 3x &gt; 13?
Oksanka [162]

Answer:

x

Step-by-step explanation:

Given inequality:

4-3x>13

In order to represent the solution on the number line, we will first solve the given inequality.

We have

4-3x>13

Subtracting both sides by 4.

4-3x-4>13-4

-3x>9

Dividing both sides by -3.

\frac{-3x}{-3} [On dividing both sides by a negative number the sign of the inequality reverses.]

x

So, solution of this inequality will range from -3 to -∞

The number line is represented below.
