13. x= 27/4 or 6 and 3/4
14. x= 27
15. x= 191/7 or 27 and 2/7
16. x= 83/15 or 5 8/15
the key to solving these is cross-multiplying and finding a common denominator, you can use photomath if you want to see the solving steps, hope this helps!

Step-by-step explanation:
Equations in parentheses get solved first: 30-10=20 and 20x5=100
Answer:
Area of the square:
12 x 16 = 192
Area of the semi circle on top:
16 - 8 = 8 is your diameter
half of 8 is 4.
I got 8 from adding the two fours on the side of that semi circle on top.
4^2 x 3.14
16 x 3.14 = 50.24
50.24 divided by 2 = 25.12
Area of the semi circle on the side:
12 - 8 = 4
4 is your diameter and half of that which would be your radius is:
2 so
2^2 x 3.14
4 x 3.14 = 12.56
12.56 divided by 2 = 6.28
Now we are going to add all the areas:
192 + 25.12 + 6.28 = 223.4 is your answer
Answer:
yes.
Step-by-step explanation:
each x value is used once and never repeated.
