![\sf-4R-2r+5](https://tex.z-dn.net/?f=%5Csf-4R-2r%2B5)
is already in simplest form.
But if you meant to say
![\sf-4r-2r+5](https://tex.z-dn.net/?f=%5Csf-4r-2r%2B5)
, we would combine the first two terms.
Adding/subtracting like terms is the same as adding/subtracting whole numbers.
![\sf-4-2=-6](https://tex.z-dn.net/?f=%5Csf-4-2%3D-6)
Therefore:
![\sf-4r-2r=-6r](https://tex.z-dn.net/?f=%5Csf-4r-2r%3D-6r)
Which gives us:
The statement that best describes the two expressions is
D. A is irrational, but B is rational
square root of 64 plus square root of 5 is 8 plus square root of 5, the square root of 5 is an irrational number which makes the entire expression an irrational number
square root of 64 plus square root of 4 is 8 plus 2 which is equal to 10 and is a rational number
Answer:
formula for ratio: you can write a ratio with :, or, /
x axis is horizontal
0= x axis 6= y axis
Step-by-step explanation:
Alright so all we are doing is adding 7/10 and 1/2
But sometimes that can be difficult because they don’t have the same denominator
In that case, we want to give them the same denominator (bottom number if the fraction)
So we do this by multiply 1/2 by 5/5 which will get you 5/10
We now have 5/10 and 7/10 which both have the same denominator (10)
So add them together and you will get 12/10
Now that’s more than 1 gallon so let’s figure out how much more
So 12/10 -10/10 (full gallon) = 2/10
So she used 1 2/10 gallons
If you want it in decimal form then it’s 1.2 (divide 2 by 10)
Hope that helped!
