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.

2. 2x = 4 2. Subtraction Property of Equality
3. X = 2 3. Division Property of Equality
Add up 3+3=6, number has to be bigger than 9 so the answer is false.
Answer:
1.02 as a decimal
1 and 1/50 as a fraction
Step-by-step explanation:
Answer:
it was -5 and then it fell 8 degrees
-5 -8 = -13 degrees F
Step-by-step explanation:
the answer is 78 kilometers.
1 cm=15 kilometers
so, 6 cm is equal to 90 kilometers.
0.8 millimetres is approximately 12 kilometers.
90 kilometers minus 78 kilometers is equal to 12.
