You basically just get a equation that needs to be answered and grab the answer and minus it by one of the two digits in front. Example: 3+2=5 is equal to 5-2=3
Answer:
B) 128.3 square yards
Step-by-step explanation:
A = (n/360 deg)(pi)r^2
where n = central angle of sector.
A = (75/360)(3.14159)(14 yd)^2
A = 128.3 yd^2
You want to isolate the variable on one side of the equation so that you can see what it's value is with respect to the other terms
You want to try to isolate the x:
First subtract 6 from both sides so you get 2x=28
Then divide both side by 2 so you get x=14 which is your answer :)
ANSWER: x=14
