Answer:
259
Step-by-step explanation:
You could set up an equation that looks like:
Then solve for 
1. subtract 92 from 251
2. add 100 to both sides
When you set up 3 * (1/3), you're both multiplying and dividing by a 3. these two cancel out, and you're left with one. 3 *(1/3) is simply 1.
12 * (1/3), when you set it up, doesn't cancel out the same. multiply straight across the top (12 * 1), then divide by the bottom (3). 12/3 = 4, so 12*(1/3) is 4.
9 * (1/9) gives you the same result as the first one. the multiplied 9 and the divided 9 cancel out, and you're left with 1.
The number of cars that have passed through the intersection is 245.
<h3>How many cars passed through the intersection?</h3>
Direct variation is when two variables move in the same direction. If one variable increases, the other variable increases.
The equation that represents direct variation is; c = wk
Where:
- c = number of cars
- w = number of wrecks
- k = constant of proportionality
1085 = k31
k = 1085 / 31
k = 35
c = 7 x 35
c = 245

Answer:
A) DEBBIE: 1p+4t=29
B) JOEY: 5p+2t=28
Step-by-step explanation:
-x+5y=20
5y=x+20
12y=2x+60
6y=x+40
x+20+y=x+40
-x from each side:
20+y=40
-20 from each side:
y=20
-x+5*20=20
-x+100=20
-100 from each side:
-x=-80
x=80
y=20
x=80
Hope this helps :)
