Answer:

x = 3

Explanation:

To simplify this equation, don't worry about the -3, since there is one on both sides. Therefore, they cancel out.

So, 9 + x = 4x

When you plug 3 in for x, it becomes:

9 + 3 = 4 x 3

12 = 12

This equation is true, therefore, x is your answer!

Andy has three planks of wood. Two planks are each 1.5 m long. One plank is 2.5m long. What is the total length of all the three

11Alexandr11 [23.1K]

Given:

Two planks are each 1.5 m long.

One plank is 2.5m long.

To find:

The total length of all the three planks.

Solution:

Two planks are each 1.5 m long. So,

First plank = 1.5 m

Second plank = 1.5 m

One plank is 2.5m long. So,

Third plank = 2.5 m

Now, the total length of all the three planks is

$\text{Total length}=\text{First plank + Second plank + Third plank}$

$\text{Total length}=1.5+1.5+2.5$

$\text{Total length}=5.5$

Therefore, the total length of all the three planks is 5.5 m.
