Multiply -1 (the - sign is equal to -1) to both numbers in the parenthesis.
-1 * 3x = -3x
-1 * -8 = 8
So now the equation looks like....
10x - 3x + 8
Now combine like terms.
10x - 3x = 7x
7x + 8 is the answer.

Step-by-step explanation:
When we draw out our triangle, we should see that we are given the horizontal leg and are trying to find the vertical leg. We use tan∅ to help solve:
tan53° = x/3.5
3.5tan53° = x
x = 4.64466
Answer:
-3/ 20
Step-by-step explanation:
-3/8 * 2/5
Rewriting
-3/5 * 2/8
Simplify the right term by dividing the top and bottom by 2
-3/5 * 1/4
Multiply the numerators and then the denominators
-3/ 20
Well it seems if you round you would get 1.81 try it
