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 number that occurs most often in a set of numbers
in this case, the number 100 occurs more than any other number in the set. This means that the mode for this set of data is 100.
Answer:956= _+_
Step-by-step explanation:
Put the Equations together,
734+356-134=956
956 = ?
make any equation that would equal 956
Ex: 955+1=956.
(I wouldn't make it that easy tho lol teacher might not get fond of you)
I think this was the right way. If not, sorry!
2.6 and 2.4. they are the decimals next to 2.5
