Answer:

8"

Step-by-step explanation:

Lᵃ/Wᵃ = Lᵇ/Wᵇ

20"/4" = 40"/Wᵇ

Wᵇ = (4"×40")/20"

Wᵇ = 160" ÷ 20"

Wᵇ = 8"

Width of rectangle B = 8 inches

Answer:

8 inches

Step-by-step explanation:

Let w be the width of rectangle B.

Since, both rectangles are similar.

Therefore, corresponding lengths and widths of rectangles A and B will be in proportion.

\therefore \frac{20}{40}  =  \frac{4}{w}  \\  \\  \frac{1}{2}  =  \frac{4}{w}  \\  \\ w = 2 \times 4 \\  \\ w = 8 \: inches

Explain the difference between an equation and an inequality. Write at least two of each, one of the form px+q and one of the fo
Triss [41]

Answer: One important difference between an equation and an inequality is that if you subtract one side of an equation from the other, you will get 0

In the case of an inequality, if you subtract one side from the other, you will get something other than 0

That’s an important fact about equations and inequalities that is often utilized in finding solutions.

When I was teaching I noticed that students frequently interpreted the =

sign to mean ‘find the answer’. It does not mean that. It only means that the expression on the left hand side has the same value as the expression on the right hand side.

Students who think that =

means ‘find the answer’ become confused when they see symbols like < , ≠

, or ≈

A further issue these days has to do with computational technology.

This issue has to do with variable assignment. In many programming languages, a statement like =+1x1

has the meaning, “Add one to the current value of x

and then reassign that value to x

.” However, the equation =+1x1

has no solution in traditional algebra.

Programming languages that use =

for variable assignment tend to use ==

to mean equality in our traditional math sense.

Though something like the meaning of =

might seem trivial and ‘obvious’ to many people, there’s actually a lot of subtle variations of understanding possible, and it is important to be aware of these nuances, because that is where confusions arise for students.

Here are 36 points lovely person but first any advice for a student - kid
Brilliant_brown [7]
I don’t have much advice, but I would make yourself a schedule and a to-do list so you stay in track, and know what you’re doing each day so you can hold yourself accountable and can’t have any excuses about “not knowing about the work” because if you’re organized and get it done fast, you will be able to know about all of you work and have beTter grades since you have more time to learn the material and turn it in on time

Thanks for the points lol
