Answer:
x = x+9
Step-by-step explanation:
well that is the only way you can do it as we do not know about what x is. also, if you meant by x + (x*9), you can represent that as x*10
Answer:
Option A
Step-by-step explanation:
The complete question is shown in the attachment.
The sum of angles in a triangle is 180 degrees.
This implies that:

m<A+138=180
m<A=180-138=42
Now we use the sine rule to find AC=b

This implies that:


Answer:
1 5/12
Step-by-step explanation:
12 1/3 - 10 11/12
We need to get a common denominator of 12
12 1/3 * 4/4 - 10 11/12
12 4/12 - 10 11/12
We need to borrow from the 12 (the whole number) because the 2nd fraction is bigger than the first
12 becomes 11 and the 1 becomes 12/12
11+ (12/12 + 4/12) - 10 11/12
11 16/12 - 10 11/12
Subtract the whole numbers
11-10 =1
Subtract the fractions
16/12 - 11 /12 = 5 /12
We are left with 1 5/12
