Answer:
Explanation contains answer.
Step-by-step explanation:
Question 1:
I would perfer to solve the first equation for y because there is only one operation to perform on both sides and it is subtraction of 2x on both sides.
The other equation requires two steps to isolate y; subtracting 3x on both sides then multiplying both sides by -1.
So basically solving the first one for y because it has coefficient 1.
Question 2:
They solved the 2nd equation for y and plugged into itself instead of plugging it into 1st equation.
Answer:
let the numbet of formal attires with Clara be X
Clara lended susan 1/2 = X/2
Clara buys 4 = X/2 +4
Answer = X/2 + 4
( as the number of formal attires originakly with Clara is not specified)
Answer:
The correct answer is B.
Step-by-step explanation:
-1/2 is equal to -2/4, so if you do -3/4 + -2/4, you get -5/4
That would be 4/6, or 2/3 simplified. As a percent, that would be 66%.

Answer:
15. a, 16. ∠GOH = 26
Step-by-step explanation:
15. A straight angle looks as a line.
16. ∠GOI = ∠GOH + ∠HOI
47 = ∠GOH + 21
∠GOH = 47 - 21 =26
∠GOH = 26
