0.5x - 2 < 5.5


Add 2 to both sides.


0.5x < 7.5

Now divide by 0.5 on both sides.

x < 15

The answer is 10
I'm going to list the locker numbers by round:
Evens) 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, etc.
2's) 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, etc.
5's) 5, 10, 15, 20, 25, 30, 35, 40, etc.
The first number to repeat is 10, so that would be the first locker Brandy opens.
Hope this helped :)

The area was of a rectangle is 6384 square yards .If the width of the rectangle is 7 yards what is the length of the rectangle
aev [14]

Answer:

The Length of Rectangle is 906.851743 yards

Step-by-step explanation:

Given :

The area of a rectangle is 6384 square yards .

The width of the rectangle is 7 yards.

To Find : The length of the rectangle.

Solution :

The formula of area of rectangle is :

Area of Rectangle = Length * Width

Since we are given that area of a rectangle is 6384 square yards and width of the rectangle is 7 yards . so putting these values in formula we get:

⇒6348 = Length * 7


⇒\frac{6348}{7} = Length


⇒906.851743= Length

Thus, The Length of Rectangle is 906.851743 yards

write the equation of the line perpendicular to y= 5/2x+3 that passes through the point (-7,9). Type an answer using slope-inter
omeli [17]

Answer:

 5y = -2x + 31

Step-by-step explanation:

Given equation:

      y = \frac{5}{2} x + 3

Coordinate  = (-7,9)

Unknown:

Equation of the line perpendicular  = ?

Solution:

The slope - intercept format of a line is given as;

      y = mx + c

where y and x are the coordinates

           m is the slope

           c is the y-intercept

y = \frac{5}{2} x + 3

 From the given equation; slope is \frac{5}{2}

       

A line perpendicular will have a slope that is negative and the inverse of this;

      slope of perpendicular line  = -\frac{2}{5}

Since y= 9 and x = -7;

  So;

            9 = \frac{-2}{5}  x (-7) + C

            9 = \frac{14}{5} + C

           C  = 9 - \frac{14}{5}   = \frac{31}{5}

Now,

       y  =  -\frac{2}{5}x +  \frac{31}{5}

mulitply through by 5;

     5y = -2x + 31
