Employees of landscaping companies built a retaining wall. They used brick to make the top 2/3 of the wall.
250 POINTS
Part A: What is the height of the brick proportion of the wall? Write an equation
Part B: Estimate the area of the whole retaining wall. A= LxW
For part c you need a equation
Part C: What is the area of the whole retaining wall? Write an equation to show your work. Compare your answer to your estimate to see whether your answer is reasonable
Answer with Step-by-step explanation:
a) 2 3/4 ÷ 3 = 11/12 feet
11/12 + 11/12 = 1 5/6
Or, you could write an algebraic equation:
2 3/4 ÷ 3 = x. (3x = 2 3/4)
x = 11/12
The height of the brick proportion of the wall is 1 5/6
b)
You know that 8 x 2 is 16. Well, you already know that the whole total of fractions, multiplied together, would probably be less that 1 and less than 1/2.
So, your rounded answer should be 16. Or 16 1/2
c)
Area = 8 1/2 x 2 3/4.
Use Distributive Property to solve the area.
(8 x 2) + (3/4 x 1/2) = x
8 x 2 = 16
3/4 x 1/2 = 3/8
16 + 3/8 = 16 3/8
x = 16 3/8
I think my answer is reasonable because I estimated 16, and 1/2. 3/8 is close to 1/2. That's why my answer is reasonable.

Answer:
x = 4
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
6*x-9-(2*x+7)=0
Pull out like factors :
4x - 16 = 4 • (x - 4)

In class today, we had 98 notebooks and 70 children.If each child gets two notebooks, how many more notebooks will we need?
Answer:
42
Step-by-step explanation:
times 70 by two to get how many notebooks needed total.
70*2=140
subtract how many notebooks you already had.
140-98=42
The no. of notebooks we need more will be equal to 42 notebooks.
It is given that no. of notebooks available is 98 and there are 70 children in class.
We have to find no. of notebooks needed more if each child gets two notebooks.
What is algebra ?
Algebra is the branch of mathematics that deals with various symbols and the arithmetic operations and the symbols are called variables.
As per the question ;
No. of notebooks we had in class = 98 notebooks
And
Total no. of children = 70 children
The no. of notebook each child gets = 2 per child
So ;
70 children will get no. of notebooks ;
= 70 × 2
= 140 notebooks
The no. of notebooks we need will be ;
= 140 - 98
= 42 notebooks
Thus , the no. of notebooks we need will be equal to 42 notebooks.

What is 2.16666666667 as a fraction?
(or what is 13/3 divided by -2/1 as a fraction)
Will give 5 stars brainlist whatever pls help!!
(13/3) / (-2/1) = (13/3) / (-2) = - 13 / (3 • 2) = -13/6
21.6666666667 can be expressed as the fraction 21 2/3 or 65/3.
13/3 divided by -2/1 is equal to -13/6.
Given that we need to convert 21.6666666667 can be expressed as the fraction and 13/3 divided by -2/1 as a fraction.
To convert the decimal number 2.16666666667 to a fraction, we can multiply both the numerator and denominator by a power of 10 to eliminate the decimal point.
Since there is only one digit after the decimal point, we can multiply by 10.
2.16666666667 x 10 = 21.666666667
Now we have the number 21.666666667 as a whole number. Since there are three repeating digits (6), we can represent them as a fraction over 9 (since 9 is the largest power of 10 that is one less than the number of repeating digits).
21.666666667 = 21 + 0.666666667
= 21 + 6/9
Simplifying the fraction 6/9, we can divide both the numerator and denominator by their greatest common divisor, which is 3.
6/9 = (6 ÷ 3) / (9 ÷ 3)
= 2/3
Therefore, 2.16666666667 can be expressed as the fraction 21 2/3 or 65/3.
For the division problem (13/3) ÷ (-2/1), we can convert it into a multiplication problem by multiplying the first fraction by the reciprocal of the second fraction.
(13/3) ÷ (-2/1) = (13/3) x (1/-2)
Multiplying the numerators and denominators, we get:
(13 x 1) / (3 x -2) = 13 / -6
Therefore, 13/3 divided by -2/1 is equal to -13/6.
