The subtraction property of inequality can be used to proof that x = 7 from x + 8 = 15
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Given that x + 8 = 15
Hence:
x + 8 - 8 = 15 - 8 (subtraction property of inequality)
x = 7
The subtraction property of inequality can be used to proof that x = 7 from x + 8 = 15

Step-by-step explanation:
f(0) = -5^0 = -1
Answer:
30+(2x+7)+63=180(sum of angles of triangle )
30+2x+7+63=180
2x+100=180
2x=180-100
x=80/2
x=40

Explanation:
The complete question is:
<em>Between the time iko woke up and lunchtime, the temperature rose by 11º. Then by the time he went to bed, the temperature dropped by 14º.</em>
<em />
<em>Write an addition expression for the temperature relative to when iko woke up. </em>
<em />
<h2>Solution</h2>
It is said that between the time Iko woke up and lunchtime, the temperature rose by 11 degrees. A rise means the temperature increased and you must add 11º.
Then, relative to when Iko woke up the temperature is:
Then, by the time Iko went to bed, the temperature dropped by 14º. A drop means that the change is negative. This means that you must add a negative number, and the additive expression is:
If you want the overall change in temperature you do the operation:
- 11 + (-14) = 11 - 14 = - 3. A net decrease of 3º.
But the answer to this question is the additive expression:
