Answer:
x= -6 | I only have an answer for #7 but you should use a website called Symbolab :)
Step-by-step explanation:
x+16+x+12+2x+15=19
<em>group like terms: </em>
4x+43=19
<em>subtract 43 from both sides:</em>
4x+43=19
-43 -43
<em>simplify</em>:
4x=-24
<em>divided both sides by 4:</em>
x=-6
Answer:
2 3/4
Step-by-step explanation:
Well, this is absolute value, so as a mixed fraction you would have to times the denominator to the whole number, and then add the answer of that to the numerator (2 x 2 x 1). After that, you should get a whole number as an answer, but make it as a fraction. (put the whole number you got on top of the denominator before (2) to make it a fraction). Then, again, since it's absolute value, then it into a negative. Hope this helps and hope it not confusing!!
