QUESTION 5

The given expression is

[tex]-5x-3x+7x[/tex]


All of these are like terms because all of them contain [tex]x[/tex].


Let us combine the first two terms to obtain an expression which is

[tex]=-8x+7x[/tex]


We finally simplify to obtain an expression which is

[tex]=-x[/tex]


The correct answer is B


QUESTION 6

The given expression is

[tex]x+x+x-10x[/tex]

All the terms in the expression are like terms because they contain [tex]x[/tex].


We combine the first three terms to obtain an expression which is

[tex]=3x-10x[/tex]


We finally simplify to obtain an equivalent expression which is

[tex]=-7x[/tex]


The correct answer is B


QUESTION 7


The given expression is

[tex]8t-9t+4t-12t[/tex]


All the terms in the given expression are like terms because they all contain [tex]t[/tex].


We combine the first two terms to obtain an equivalent expression which is

[tex]=-t+4t-12t[/tex]

We again combine the first two terms to obtain an equivalent expression which is


[tex]=3t-12t[/tex]


We finally simplify to obtain an expression which is

[tex]=-9t[/tex]


The correct answer is A


QUESTION 8

The given expression is

[tex]x+4x-6y+7y[/tex]


The first two terms in the expression are like terms because they contain [tex]x[/tex]. The last two terms in the expression are also like terms because they contain [tex]y[/tex].


When we combine the first two terms we obtain an equivalent expression which is

[tex]=5x-6y+7y[/tex]

When we again combine the last two terms we obtain an equivalent expression which is

[tex]=5x+y[/tex]

This final expression cannot be combined again because they are not like terms.

Therefore the correct answer is D


QUESTION 9

The given expression is

[tex]3ax+3x+5ax-x+5a+10ax[/tex]


We group like terms to obtain,

[tex]3ax+5ax+10ax+3x-x+5a[/tex]


We combine the first three terms to obtain,

[tex]18ax+3x-x+5a[/tex]


We combine the middle two terms to obtain,


[tex]18ax+2x+5a[/tex]


The correct answer is B


QUESTION 10


The given expression is

[tex]4m+6mn-2m-2mn+7m[/tex]


We group like terms to obtain an equivalent expression which is

[tex]=4m-2m+7m+6mn-2mn[/tex]


We combine the first three terms to get,

[tex]=9m+6mn-2mn[/tex]


We now combine the last two terms to get,

[tex]=9m+4mn[/tex]


The correct answer is A
