Answer:
The prices for a calzone and for soda as an ordered pair (c,s) is (5,1)
Step-by-step explanation:
Let c be the prize of calazone
Let s be the prize of soda
She buys two calzones and three sodas she pays $13
So, 2c+3s=13
She buys three calzones and two sodas she pays $17
So, 3c+2s=17
Plot the equations on graph
2c+3s=13 --- Green
3c+2s=17 --- Blue
Intersection point will give the intersection point
So,(c,s)=(5,1)
So, Option c is correct
The prices for a calzone and for soda as an ordered pair (c,s) is (5,1)
-10 -10y = 10
+10 +10
-10y = 20
20/-10 = -2
Y = -2
Answer : 153 miles
Explanation : first take 134.29 & subtract the 14.95 base fee which give you 119.34 . now divide 119.34 by 78 which gives you 1.53. so he drove 153 miles.
equation : 14.95+ 0.78x = 134.29 . to double check just multiply 153 x 0.78 and add $14.95 which gives us the total of $134.29
Answer:
x = 
Step-by-step explanation:
4x-y+2z = 8x+y-4
4x-8x-y+2z = 8x - 8x +y-4
-4x -y +2z= y-4
-4x -y+y +2z = y+y-4
-4x +2z = 2y-4
-4x+2z-2z = 2y-2z-4
-4x = 2y-2z-4
=
