Answer:
d = 5
Step-by-step explanation:
We want to know what d would be when x = -1, so we can start off by plugging in -1 for x to get the following equation: 
. On the left hand side, 2 negatives become a positive sign, so the -(-1) becomes a +1, and 8+1 would equal 9. On the right hand side, we just multiply 2 and -1 to get -2. So, the equation now looks like this: 
. We know that 
= 3, so we would get 3 = d-2. THen we would add 2 to both sides to get d = 5. Hope this helps!
Answer:
-19/132
Step-by-step explanation:
To add fractions, find the lowest common multiple of the two denominators and multiply accordingly to make both denominators the same. In this case, the lowest common multiple of 11 and 12 is 132, so we need to multiply the first number by 12 and the second by 11. So we get 
= 
=
Move all terms that don't contain x to the right side and solve.
x=−5/3−y/3

Answer:
here you go
Step-by-step explanation:
35+a+b+c=270
35+a=90
a+b=180
35+90+c=180
Andy was correct
2639456 is rounded to 2640000 because the 9 from 39,456 rounds up to 0 and the three changes to a 4
Elizabeth rounded down instead
