First, solve for x
x + y = 6
+
2x - y = 9
——————
3x = 15
x = 5
then just substitute that into one of the equations
(5) + y = 6
y = 1
then make into an ordered pair (x,y)
(5, 1)
Answer: 7/24
Step-by-step explanation:
Five-eighths means 5/8
One-third means 1/3
The difference between 5/8 and 1/3 is
5/8 - 1/3 = 7/24
Therefore, the smallest number of equally sized pieces each fraction bar can be broken into 7/24
The absolute value is 10/7
Answer:
n = -1.25
Step-by-step explanation:
S(ABCD) = AB × AD

S(ABCD) = CD × AD
2n × (4n + 5) = CD × (4n + 5)
n = -1.25
