Answer:
Step-by-step explanation:
0.35
0.453
4/5
For the square part- 10*10=100sq in
For the half circle
r=5
5*5=25
3.14*25=78.5
Part A would be the second option, as well as part B
25%
If you are buying 2 shirts for the same price, you have to calculate the cost of the shirt at half price first (1 piece of the pie) and then add it the original price (2 equal pieces of the pie since you just divided that to the price of the second shirt). That would be considered 3 out of 4 pieces off the pie or 75%. Your savings would be 25%.

Let's solve ~
Here, 6x is present on both the sides of equation so they cancel out ~ therefore there is no one solution satisfying the equation ~
