Answer:
Error: Sariah treated every term as though it were an x-term. 5 and -4.5 are constants that cannot be combined with the x-terms. They can only be combined with each other.
Correct solution: 31x + 0.5
Strategy: Pay attention to the variables.
Step-by-step explanation:
In her first step, it appears Sariah added 13x and 5 to get 18x. These terms are not <em>like terms</em>, so cannot be added in this way. An appropriate strategy is to first identify all the terms with the same <em>variables</em> (x in this case), then add their <em>coefficients</em>.
... = x(13 +17 +1) +5 -4.5
Likewise, all the <em>constant</em> terms can be added.
... = 31x +(5 -4.5)
... = 31x + 0.5
Answer:
The first answer is 1/3 the second answer is also 1/3
Step-by-step explanation:
If you count the number of names there are and take two out that would round down from 2/6 to 1/3. The answer is the same for both questions.
A to the second power is the answer to this problem
-8c^3/d^6 is equivalent to the expression
A bar graph or line graph. Hope I helped!!
