Answer:
( , ) or x = y =
( 2.57 , 4.18) or x = 2.57 y = 4.18
Step-by-step explanation:
Use elimination:
Find the least common multiple between x or y in this case use -6 and 5 (make sure there are opposite signs)
11x - 6y = 2 multiply entire problem by 5
-8x + 5y = 3 multiply entire problem by 6
55x - 30y = 10 combine problems
<u>-48x + 30y = 18</u>
7x + 0y = 18
7x = 18 = Plug into one equation to find y
11() - 6y = 2
- 6y = 2
-6y = -
y=

Answer:
C.
Step-by-step explanation:
Since both terms are perfect squares, factor using the difference of squares formula to get you the answer
(7x+9)(7x-9)
Answer:
9/2
2+2+2+2=8
9-8=1
2 can go into 9 four whole times
4 1/2
Step-by-step explanation:
Answer:
Data set B has less variability then Data Set A because the range of B is 29 and the range of A is 30.
Step-by-step explanation:
The range of Set A is 44-14 = 30 and the range of B is 38-9 = 29.
