Answer:
51
21
Step-by-step explanation:
Let x be larger number
Let y be smaller number
x - 2y = 9
==>
x = 9 + 2y
AND
x + y = 72
SO
(9 + 2y) + y = 72
==>
3y = 72 - 9 = 63
==>
y = 21
SINCE
x = 9 + 2y = 9 + (2×21)
==>
x = 51
S(x,y)
(0+x)/2=5 x=10
(4+y)/2=-8 y=-20
So the coordinates for S is (10,-20)
Answer:
Amount Dan has = $17
Amount Ann has = $27
Amount Pablo has = $34
Step-by-step explanation:
Total amount they have = $78
Let
Amount Dan has = x
Amount Ann has = x + 10
Amount Pablo has = 2x
Total = Dan + Ann + Pablo
78 = x + (x + 10) + 2x
78 = x + x + 10 + 2x
78 = 4x + 10
78 - 10 = 4x
68 = 4x
x = 68/4
x = 17
Amount Dan has = x = $17
Amount Ann has = x + 10
= 17 + 10
= $27
Amount Pablo has = 2x
= 2(17)
= $34
Answer:
C
Step-by-step explanation:
The linear inequality has the same properties of its equation as slope intercept does. This means 
where m is the slope and b is the y-intercept. The y-intercept here is 2 and it has a positive slope of 4. This means only C or D are options. Then test a point to determine in the shaded region to determine the sign.
(0,0) --->
--->
is true so (0,0) is in the shaded portion. C is the solution.
Answer:
The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number in the distribution from the highest.
