2. 1/2, because it is twice as big as C, which takes up 1/4 of the space.

3. 1/8, because both A and D together take up 1/4 of the space, and they are both the same size

4. 1/3, because the triangles around it each take up 1/6 of the space

5. 1/6, because it is half as large as square J, which takes up 1/3 of the space

The normal yearly growth of a plant is 60 inches. The normal growth was ten inches more than twice the amount of last year. What
Usimov [2.4K]

The growth of the plant last year was 25 inches if the normal growth was ten inches more than twice the amount of last year.

<h3>What is linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The normal yearly growth of a plant is 60 inches.

Let's suppose the growth of the plant last year was x

The normal growth was ten inches more than twice the amount of last year.

From the above statement:

10 + 2x = 60

2x = 50

x = 25 inches

Thus, the growth of the plant last year was 25 inches if the normal growth was ten inches more than twice the amount of last year.
