is the expressions (5•2) x equals to the expresion 10x? Explain your answer
Please help mee !
Answer:
No
Step-by-step explanation:
It would be x(5*2)
Basically what you put just written correctly
Answer:
yes it is 10x
Step-by-step explanation:
you just simply multiply 5 and 2 to get 10 and keep the x and put it next to the 10. Therefore, (5•2) x = 10x

samar wrote a list of three square numbers. which of the following could be on samars list?
A. 4, 6, 8
B. 4, 7, 10
C. 4, 8, 12
D. 4, 9, 16
Option A "4, 6, 8".
This is because when we multiply 2x2, we get 4, then we add +2 with 4, we get 6, then we add again +2 with 6, we get 8. So, a list of three square numbers is completed.
Therefore, Option A is the correct answer.
Thank You...

The average of five numbers is 34. Two of the numbers are the same, and the other three are 49, 25, and 42. Find the value of the two numbers missing numbers.
Answer:
Both numbers = 27
Step-by-step explanation:
( x + x + 49 + 25 + 42)/ 5 = 34 Multiply both sides by 5
(2x + 49 + 25 + 42) = 34*5 = 170 Combine the left
(2x + 116) = 170 Remove the brackets.
2x + 116 = 170 Subtract 116 from both sides
2x = 170 - 116
2x = 54 Divide by 2
x = 54/2
x = 27
Check
27 + 27 + 49 + 25 + 42
170 / 5 = 34
It does check out.
27 is right.
f (8^9)p = 8^18, what is the value of p? (5 points)
A 2
B 9
C 10
D 18
Answer:
A
Step-by-step explanation:
I'm assuming p is an exponent.
You can multiply the exponent p with 9
8^9p = 8^18
Now we know that some number times the exponent 9 gives us 18.
Now, we isolate for p, by putting 9 on the other side, we know we can do this because both number have the same base (8)
therefore, 9p=18
p=18/9
p=2
What are the equations?
1. Two more than the product of 3 and a number is -10. Determine the number.
2. The sum of three times a number and 20 is 11. Determine the number.
3. Seven-tenths of a number is 5.6 Determine the number.
Step-by-step explanation:
1. Let the number be a
2 + 3a = (-10)
3a = -10 - 2
3a = -12
a = -12/3 = -4.
2. Let the number be x
3x + 20 = 11
3a = 11 - 20
3a = -9
a = -9/3 = -3
3. Let the number be n
7x/10 = 5.6
x = 5.6 × 10/7
x = 56/7
x = 8

what is rounded 6285 to the nearest hundred , would it be 6000? and why please
Answer:
6285 rounded to nearest hundred would be 6300.
6000 isn't right because you are rounding it to nearest thousand i.e. 6000.
Hope you get this
Answer:
No. It would be 6,300.
Step-by-step explanation:
To the nearest thousand, it would be 6,000.
To the nearest hundred, it would be 6,300.
To the nearest ten, it would be 6,290.

Number 75: Find the length of side x.
Answer:
Step-by-step explanation:
Unless you know that the top angle is a right angle (an assumption you should never make, but I will do it here because there is no other way to do it.)
Find the missing side of the triangle that is on the bottom triangle
b^2 = c^2 - a^2
b = ?
c = 11
a = 10
b^2 = 11^2 - 10^2
b^2 = 121 - 100
b = sqrt(21)
Now using the fact that
b / 10 = 10 / (x - b)
We know b from the previous problem
b = sqrt(21)
So now cross multiply
b ( x - sqrt(21) ) = 100
sqrt(21) * x - 21 = 100 Add 21 to both sides.
sqrt(21)x = 121 Divide by sqrt(21)
x = 121/sqrt(21)
x = 26.4
My first inclination is to tell your teacher it is unsolvable. Or you can ask him or her to show you how it is done. If they think the assumption I have made is correct, then you have the answer. Technically however, there is no answer.

Step-by-step explanation:
breadth=x
length is 5m long then breadth
length=x+5
Perimeter=2(length+breadth)
subtitute values in formula:
150=2(x+5+x)
2x+5=150/2
2x+5=75
2x=75-5
2x=70
x=70/2
x=35
breadth=35m
length= x+5
length=35+5
length=40m
[tex] \text{Let us assume the breadth be } \purple{\frak{a}}[/tex]
The length is 5m more than its breadth
[tex] \text{The length be} \: \green{\frak{a + 5}}[/tex]
Here we need to get both breadth and length by finding out a
