Answer:
(2/3,2)
Step-by-step explanation:
3*2/3+4
simplify 2=2
-3x-1 = 2-(-3)
-3x-1 = 2+3
-3x-1 = 5
-3x = 5+1
-3x = 6
x = 6/(-3)
x = -2
7x + 2y = 48
7x + (2x3) =48
7x + 6 = 48
7x = 48 - 6
7x = 42
--> x = 6
Lets label hot dogs as 'h' and soft drinks as 'd'
6h + 4d = 13
3h + 4d = 8.50
We can solve by process of elimination.
Subtract the first equation from the second one.
We get:
3h = 4.5
Solve for h
<span>h = 1.5 </span>
<span>That means that the hot dog costs $1.50 which is answer choice </span>D.
<span>Hope that helps :)</span>
If you replace c with -4 and y with 2, your equation becomes -4 - 14. Evaluate and you get -18, which is your answer.
