The answer is $7.75 -3.25-2.75x-4=$7.75
Alright so
Surface area = (width x height) + (length x width) + (length x height) + (length x side)
The expression 15t – 2t not equivalent to 2t – 15t because the negative sign in 15t – 2t belongs to the term 2t.
Solution:
Given expressions are 15t – 2t and 2t – 15t.
To determine 15t – 2t is equivalent to 2t – 15t or not.
Substitute t = 2 in above two expressions.
15t – 2t = 15(2) – 2(2)
= 30 – 4
= 26
2t – 15t = 2(2) – 15(2)
= 4 – 30
= –26
The values of the expressions are different when t = 2.
So, 15t – 2t is not equivalent to 2t – 15t.
Hence the expression 15t – 2t not equivalent to 2t – 15t because the negative sign in 15t – 2t belongs to the term 2t.
-12x/-4= -27
(-4)-12x/-4 it will cancel the 4 but you gotta multiply on the other side by 4 too
now have -12x =108
-12x=108
divide 108 by -12x which x=-9
Sorry if I'm wrong - This is how I learned to subtract fractions in the 7th grade
First, I would line up the fractions side-by-side:
5/6 1/8
Then, my teacher would tell me to look at the numerators and subtract those - The answer would be 4
Next, she would say to do the same to the denominators - The answer is 2
4/2 is your answer I believe
Hope this helped! :)
