Answer:
We are given that 4 lb of candies are bought for $9.00
Therefore, the price of 1 lb of candies is:
Now the amount of candies that can bought for $12.00 is:
lb
Therefore, 5.3333 lb of candies can be bought for $12.00
( 'x' is not 144 .)
The supplement of an angle is (180 - x) .
The problem says that (2/3) of 'x' is equal to (180 - x) .
180 - x = 2/3 x
Multiply each side by 3 :
( Note: 3 x 180 = 540 .)
540 - 3x = 2x
Add 3x to each side:
540 = 5x
Divide each side by 5 :
<u>x = 108°</u> .
