Answer:

$13*[4+(9-2)]=143$

Step-by-step explanation:

we have

$13*[4+(9-2)]$

step 1

Solve $(9-2)$

$(9-2)=7$

substitute

$13*[4+7]$

step 2

Solve $[4+7]$

$[4+7]=11$

substitute

$13*[11]$

step 3

Solve $13*11$

$13*11=143$

therefore

$13*[4+(9-2)]=143$

Add the two expressions. −2.4n−3 and −7.8n+2

Sphinxa [80]

Answer:

-10.2n - 1

Step-by-step explanation:

We have two expressions in variable n and we have to add the two expressions.

An important thing to note is that only like terms can be added. i.e. the term with "n" can only be added or subtracted to the term with "n". Similarly a constant can only be added or subtracted to a constant.

$(-2.4n-3)+(-7.8n+2)\\=-2.4n-3-7.8n+2\\=-2.4n-7.8n-3+2\\=-10.2n-1$

Thus, the two given expressions add up to -10.2n - 1
