Answer:
Step-by-step explanation:
Can the sides of a triangle have lengths 5, 8, and 11?
You can just plug in one of the points to each equation until you get an equality that is true.
I chose to use (-3,2)
1. 5x+3y=1
5(-3)+3(2)=1
(-15)+ 6 = 1
(-9) = 1 <<<(FALSE)
2. x+5y=3
(-3)+5(2)= 3
(-3)+10= 3
7=3 <<<(FALSE)
3. 3x+5y=1
3(-3) + 5(2)= 1
(-9)+10=1
1=1<<<(TRUE)
So, the correct equation is 3x+5y=1.
Make sense?
Add 4/5 and 1/5 to make 5/5 or 1 mile the subtract 1 from 2 1/2 to equal 1 1/2 miles

Step-by-step explanation:
Here you go mate
Step 1
10=3c-2 Equation/Question
Step 2
10=3c-2 Simplify
10=3c-2
Step 3
10=3c-2 Add +2
3c=12
Step 4
3c=12 Then you divide the exponents by 3
answer
c=4
