3x + 4 - 5 (x + 2) is an equation ; -6 = 2x

Given,

3x + 4 - 5 (x + 2)

We have to find this is whether an expression, equation or inequality.

First we have to solve this:

3x + 4 - 5 (x + 2)

3x + 4 - 5x - 10

- 2x - 6

-6 = 2x

Here, we can identify this is an equation.

What is an equation?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

What's the answer for this problem number 6 and how did you get your answer?
lorasvet [3.4K]

\frac{7}{b + 5} =  \frac{10}{5} \\

\frac{7}{b + 5} = 2 \\

Multiply the sides of the equation by ( b + 5 ) :

7 =2 \times (b + 5)

7 = 2b + 10

Subtract the sides of the equation minus 10 :

7 - 10 = 2b

- 3 = 2b

Divided the sides of the equation by 2 :

b =  -  \frac{3}{2}  \\

And we're done.

An architect is making a plan for a new circular playground. If the picture below is the playground, how much fencing needs to g
maw [93]

Answer:

Length of the fencing required = 201.06 meters

Step-by-step explanation:

Architect is planning a circular playground with diameter = 64 m

We have to calculate the fencing required to cover this playground.

Length of fencing = circumference of the playground

Since circumference of a circle = π × (Diameter)

                                                    = 64π

                                                    = 201.06 meters

Therefore, length of fencing required to keep the kids in a circle will be 201.06 meters.
