40% of 20 equals 8.

First, we need to think that 20 is our 100%.
Let's make the variable v as the value we're looking for.

20/v = 100/40
We need to multiply both sides of the equation by v.
(20/v) * v = (100/40) * v

Now, we're left with 20 = 2.5x

We need to divide both sides of the equation to isolate the variable x.
20/2.5 = 2.5x/2.5
8 = x

Our final answer is 8.

Sample Work Suppose you are constructing a LEGO Technic Land Rover Defender with a total of 2573 pieces. You have already put to
ahrayia [7]

Answer:

The relationship is linear.

Step-by-step explanation:

A linear relationship is a trend in the data that can be modeled using a straight line, such that a relationship between two variables x and y is linear if the rate of change is constant. That is, whenever x increases by 1, and it always increases by the same constant.

The constant by which y increases as x increases by 1 is called the slope and is denoted by the letter m. Being b the y-intercept, the linear relationship is modeled by the expression:

y=m*x + b

In this case x represents the minutes and y is the total number of pieces put together, so that each time x (minutes) increases by 1, "y" increases by 5 pieces. So knowing that you have already collected 253 pieces, the expression of the linear relationship is:

y=5*x + 253

The relationship is linear.
