Rewrite equations
Y/7=15/3 Y/7=5 Now multiply out 7 Y=5×7 Y=35 To check
35/7=15/3
5=5 it checks
9514 1404 393
Answer:
see attached
Step-by-step explanation:
Each point moves to the same distance on the other side of the mirror line. The slope of the mirror line is 1, so the points move along a line perpendicular to that, one with a slope of -1. You can make sure the distances are the same by counting the grid squares.
I would use elimination
2x+3y = 7
2x-y = -5
Subtract those equations
4y = 12
Y = 3
Now plug in 3 for any y value
2x - 3 = -5
2x = -2
X = -1, y = 3
Answer:
220 candy bars
Step-by-step explanation:
Let the number of candy bars sold=c
Let the number of fruit snacks sold=f
A total of 650 items were sold.
Candy bars are sold for $2.50
Fruit snacks are sold for $1.50
Total Income =$1,195
- Therefore: 2.5c+1.5f=1195
We solve the resulting system of equation for c, the number of candy bars sold.
From the first equation, f=650-c
Substitute f=650-c into 2.5c+1.5f=1195
2.5c+1.5(650-c)=1195
2.5c+975-1.5c=1195
Collect like terms
2.5c-1.5c=1195-975
c=220
Therefore, 220 candy bars were sold.
