Answer:
A
Step-by-step explanation:
Remark
The trick here is convert what you have to Ax + By = C
Solution
<u><em>Given</em></u>
y - 3 = 1/2 ( x + 6) Multiply both sides by 2
<em><u>Solve</u></em>
- 2(y - 3) = 2 * 1/2 (x + 6) Do the multiplication
- 2(y - 3) = x + 6 Remove the brackets
- 2y - 6 = x + 6 Add 6 to both sides.
- 2y - 6 + 6 = x + 6 + 6 Combine
- 2y = x + 12 Subtract x from both sides.
- -x + 2y = x - x + 12 Combine
- -x + 2y = 12
Answer
or
- When you multiply through by - 1 you get x - 2y = - 12 which is A
Answer:
x = 21
Step-by-step explanation:
3x = 16 * 4 = 64
x = 64/3
x = 21
Well when you round to the nearest 10 it will be 1 number after the point (this is due to that 10 only has one 0.) now we know that if there is a number bigger than 5 besides the number they ask you in this case the first after the point you will add 1 to that number. in this case you will add 1 to the 3. this will give you the answer of 56.4
