7x9=(x 9)+(x)
Answers
Step-by-step explanation:
7 × 9 = (? × 9) + (? × ?)
7 × 9 = (3 × 9) + (4 × 9) or (4 × 9) + (3 × 9)
The required numbers are 3, 4, and 9 to create the expression that is equal to 7 × 9.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.
We have been given numbers are 2, 3, 4, 6, 8, and 9.
To determine numbers create a different expression that is equal to 7 × 9.
Here substitute the numbers 3, 4, and 9, and we get
⇒ 7 × 9 = (3 × 9) + (4 × 9) = 63
⇒ 7 × 9 = (4 × 9) + (3 × 9) = 63
Therefore, the required numbers are 3, 4, and 9 to create the expression that is equal to 7 × 9.

The width of a rectangle is 5 less than twice its length. If the area of the rectangle is 88 cm², what is the
length of the diagonal?
The length of the diagonal is
cm.
Give your answer to 2 decimal places.
Answers
Answer:
200cm^2
Step-by-step explanation:
When we need to find length of a rectangle we need to divide area by breadth.
Length of a rectangle = Area ÷ breadth.
ℓ = A ÷ b.
Similarly, when we need to find breadth of a rectangle we need to divide area by length.
Breadth of a rectangle = Area ÷ length.

Answers
Answer:
No. He was incorrect.
Step-by-step explanation:
10 4/5 = 10 8/10.
=> 10 7/10 < 10 8/10
The above inequality is correct.
Hoped this helped.
The inequality written by Frankie is incorrect. so 10 7/10 < 10 8/10 inequality is correct.
What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solutions to that equation or inequality.
We have been given that Frankie and Gus swam for 10 minutes. When the time was up; Frankie completed 10 7/10 laps and Gus 10 4/5 had completed laps.
Since Frankie wrote the inequality to show who swam the longest distance as;
10 7/10 > 10 4/5
We can see that the fraction are;
10 4/5 = 10 8/10.
Thus, the inequality written by Frankie is incorrect.
So, 10 7/10 < 10 8/10
This inequality is correct.

The increasing annual cost (including tuition, room, board, books, and fees) to attend college has been widely discussed (Time.com). The following random samples show the annual cost of attending private and public colleges. Data are in thousands of dollars.
Private Colleges
53.8 42.2 44.0 34.3 44.0
31.6 45.8 38.8 50.5 42.0
Public Colleges
20.3 22.0 28.2 15.6 24.1 28.5
22.8 25.8 18.5 25.6 14.4 21.8
(a) Compute the sample mean (in thousand dollars) and sample standard deviation (in thousand dollars) for private colleges. (Round the standard deviation to two decimal places.)
(b) Compute the sample mean (in thousand dollars) and sample standard deviation (in thousand dollars) for public colleges. (Round the standard deviation to two decimal places.)
(c) What is the point estimate (in thousand dollars) of the difference between the two population means? (Use Private − Public.)
We estimate that the mean annual cost to attend private colleges is $ more than the mean annual cost to attend public college
