Answer:
-7
Step-by-step explanation:
Lets assume the number Peggy is thinking of be "x".
Now as given, when twice the number is added to three times one more than the number. We can write it as
∴
--- Equation 1
Again, it is given that Peggy gets the same result as when she multiplies four times one less than the number.
∴
-- equation 2
Next, we can equate both the equation 1 and 2 as it is given that result is same.
![2x+3(x+1)= 4(x-1)](https://tex.z-dn.net/?f=2x%2B3%28x%2B1%29%3D%204%28x-1%29)
Let´s distribute 3 into
and 4 into ![(x-1)](https://tex.z-dn.net/?f=%28x-1%29)
⇒ ![2x+3x+3=4x-4](https://tex.z-dn.net/?f=2x%2B3x%2B3%3D4x-4)
⇒ ![5x+3=4x-4](https://tex.z-dn.net/?f=5x%2B3%3D4x-4)
Subtract both side by 4x and 3
∴ ![x=-7](https://tex.z-dn.net/?f=x%3D-7)
∴ Peggy was thinking of -7
You would multiply 2 1/2 and 3 3/4, which would give you 9.375 or as a mixed number 9 7/8
Here is the value of each decimal digit value
.4⇒ tenths place
.01⇒hundredths place
.006,thousandths place
So .416 is .416 rounded since there is nothing to round to
In other words, its already rounded to the nearest thousandths
Its kinda a trick question to make sure you know your place values
Answer: ![9-(0+1+2)](https://tex.z-dn.net/?f=9-%280%2B1%2B2%29)
Step-by-step explanation:
We have given the numbers = 2,0,1,9
We can use addition and subtraction operation to the given numbers such that the answer will be equals to 6.
We can add 2 ,0 and 1 and then subtract from 9 , we will get 6.
So the required expression can be
![9-(0+1+2)\\=9-(3)\\=9-3\\=6](https://tex.z-dn.net/?f=9-%280%2B1%2B2%29%5C%5C%3D9-%283%29%5C%5C%3D9-3%5C%5C%3D6)
hence, the required expression can be ![9-(0+1+2)](https://tex.z-dn.net/?f=9-%280%2B1%2B2%29)
The slope is -2/3.
You have to do -2-2 and you get -4.
Then you do 12-6 and you get 6.
The final step is to do -4 divide 6 and you get -2/3.
