Answer:
First Question: <u>63 coins are not nickels.</u>
Second Question: <u>63+n=91</u>
Step-by-step explanation:
For your first question: 29+21=50 and 50+13=63. 63 coins are not nickels.
For your second question: You can do 29+21+13+n=91, I just simplified and said 63+n=91. You can choose.
Hope that this helps! Good luck with what you're working on!
Answer:
0.8 is your answer
Step-by-step explanation:
The formula for b from the given area is equal to (2A / h).
As given in the question,
Formula to find area of a triangle is equal to A = (1/2) b h
b represents the base of the triangle
h represents the height of the triangle
A = (1/2) b h
Multiply both the side by 2 in area formula
2A = b h
Divide both the side by h
b = (2A) / h
Therefore, the formula for b from the given area is equal to (2A / h).
The complete question is:
The formula A = (1/2)b h represents the area of a triangle where A represents the area, b is the base of the triangle and h is the height of the triangle. 1. Solve this formula for b.

The simplified expression for the area of the rectangular table is Three-halves x squared, 3x²/2
<h3>What is the area of the rectangular table?</h3>
Since the carpenter built a square table with side length x. Next, he will build a rectangular table by tripling one side and halving the other.
To find the area of the rectangular table, we know that Area, A = LW where
Now, since the length of the square is x, and the rectangular table has one side of the square tripled and halving the other side .
So,
let
- length of the rectangular table = L = x/2 and
- width of rectangular = W = 3x
So, the area of the rectangular table A = LW
= x/2 × 3x
= 3x²/2
So, the simplified expression for the area of the rectangular table is Three-halves x squared, 3x²/2

Answer:
See below.
Step-by-step explanation:
Well first, we need to find the weight of the table. We know that 8 boxes weighs a total of 240kg (since each box weights 30kg). Thus, we can conclude that the table weighs 70kg by doing 310-240=70.
Now, we can write our function. Let 
equal the amount of boxes.
The table is a set weight, so that would be our constant.
Thus, we will have:
30x represents the weight each box of book adds to the total. One box equals 30kg, 2 boxes equal 60kg, etc.
The 70 represents the unchanging weight of the table.
In terms of W(x), it will be:
