Answer:
d) ordered pairs are equal
e) ordered pairs are not equal
Step-by-step explanation:
d) ( 3+4 , 2 - 1)
x-co ordinate = 3 + 4= 7
y-co ordinate = 2 - 1 = 3
(3+ 4 , 2-1) = (7 , 3)
(3+4 , 2-1) & ( 7 ,3) are equal
f)Compare the x -co ordiante and y - co ordiante of the two pairs
p +q = q + p {addition closed under commutative property}
but q - p ≠ p - q {Subtract is not closed under commutative}
(p +q, q - p) & ( q + p , p -q ) are not equal
Let the numbers be x and y; x being the larger number and y being the smaller.
Given,
x + y = 2* (x - y)
x + y = 2x - 2y
x = 3y
Also given,
x = 6 + 2y
3y = 6 + 2y
--- y = 6
Thus, x = 3y = 3*6 = 18.
Therefore, the numbers are 18 and 6.
Answer:
12
Step-by-step explanation:
Since 15 is 3 times the ratio you multiply 4 by 3
