Answer:
Statements Reasons
1. 2x + 11 = 15 1. Given
2. 2x = 4 2. Subtraction Property of Equality
3. X = 2 3. Division Property of Equality
Step-by-step explanation:
An equation can be solved and its solution proven using algebraic theorems and properties. To create a proof, form two columns. Label one side Statements and the other Reasons.
Begin your proof listing the any information given to you. List as the reason - Given.
Then list the next step which here would be to subtract by 11 on both side. The reason is Subtraction Property of Equality. Subtraction is the inverse of addition. Inverse axiom is another acceptable reason.
Then divide both sides by 2. The reason is Division Property of Equality or Inverse axiom once again. See the proof below.

Answer:
The sales tax is $19.80
The total cost is $349.80
Step-by-step explanation:
To find the sales tax, multiply 330 by 0.06 (6%)
To find the total cost add the sales tax, 19.80 with 330
Since the sandwich cost 3 times as much as the chips and the sandwich is $6 then the chips must cost $2.
C = 6(5) + 2b
42 = 30 + 2b
12 = 2b
6 = b
Answer: Casey bought 6 bags of chips
Answer:
A
Step-by-step explanation:
Just take b in another side by neg-
and divide by 2 , that's it.
