Answer:

X=4

Step-by-step explanation:

  1. The first thing you would do is to make it so there is only x's on one side. To do this add the x on both sides
  2. This would make it so you have 6x-3=21
  3. Plus the 3 on both sides
  4. This would give you 6x=24

Answer:

X=4 Hope it helps Lol

Step-by-step explanation:

  5*x-3-(21-x)=0

Step by step solution :

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  6x - 24  =   6 • (x - 4)

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    6   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    x-4 = 0

Add  4  to both sides of the equation :

                     x = 4

One solution was found :

                  x = 4

What is the value of st÷(6r) if r=5, s=32, and t=45
Lana71 [14]
S = 32 and t = 45
 
You replace the letters into numbers...

Since (st) is the same thing as (s × t), it would be 32 × 45, which equals to 1,440.

Then replace the r with 5, so now it's (6 × 5), instead of (6r).

st ÷ (6r) → 1,440 ÷ 30 = 48

Value of st ÷ (6r) = 48

The figure below shows a circular fountain in a park with a garden to be planted with flowers. The parks department wants to pla
Dominik [7]

Answer:  The answer is 284.

Step-by-step explanation:

The area of the garden is an annulus whose,  

Outer diameter = 18 ft  

Inner diameter = 18 ft - 2*3ft = 12 ft

Therefore,  

Outer radius = 18/2 = 9 ft  

Inner radius = 12/2 = 6 ft  

 Area of garden = Area of annulus  

 Area of garden = π*(9 ft)2 - π * (6 ft)2

 Area of garden = 142  

 Given:  

2 flowers are planted per square foot.  

 Therefore for 142 ft2,  

Number of flowers required = 2*142 = 284  

 The answer is 284.
