Answer: B
Explanation:
We can substitute burgers for m and drinks for p, since all burgers are the same price and drinks are the same price, substitute the 3 burgers and 2 drinks into
3m+2p
The only right answer for this equation is $13.50, substitute the 5m+4p=$23.50 and your only right answer is B

Answer:
x = -7
Step-by-step explanation:
The given equation is :
-30=5(x+1)
We need to solve the equation.
Use associative property on RHS.
-30 = 5x+5
Subtract 5 from both the sides.
-30-5 = 5x+5-5
-35 = 5x
x = -7
Hence, the value of x is -7.
