Both are correct they just chose a different variable to solve for first. they will both get correct answers if they do the rest correctly.
Answer:
Explanation:
4x + 2x = 180 degree
6x = 180
x = 180/6
x = 30
Therefore, x = 30 degree
The answer is 14. This is because 63=3+x+3x-4. Then You just subtract it and then you get 64=4x. Then you just divide it and then you get x=16.
The question tells us to find or to calculate how much would Chris pay for the coat during the sale. So to calculate the you must first analyze the formula that is given which is C=0.765+0.06(0.765x) while the variablec is the cost of an item and the X represents the price of the coat and the price of the coat on sale would be 81.09
