Answer:
90
Step-by-step explanation:
PVQ = 60 an RVS = 30, 60 + 30 = 90
To solve this, you distribute the -y to both terms, 2 and 4y.
It will look something like this: (2*-y)+(4y*-y)
When you simplify, look for any like terms that can be combined, and if none, then leave it as it is.
Your final answer will be: -2y-4y^2
Answer:
for a it would be 11/18 and for b it would be 4/9
Step-by-step explanation:
This is because I did the same butterfly method. 5 times 5 times 18 which is 90 for 5/9 and 9 times 18 is 99 for 11/18, you can also write it as 5/9 and 11/18 but cross multiply. This is also what I did with the second one.
You can use number patterns to find the LCM of 120 and 360 by multiplying 120 by 1,2,3,4,5,6,and so on and do the same with 360 until you find the least number that they have in common.
No. only elena is correct
explanation: in order to solve the equation you first need to subtract 2d from both sides so it’ll look like this
8d-2d = 2d-2d
then you need to combine like terms (the new terms you added are both negative so it cancels out the right side) and it’ll look like this
6d = 0
finally, to find d, divide both sides by 6 because its being multiplied by d
6d/6 = 0/6
zero divided by anything is zero so you are left with:
d = 0
