Answer:

A. 33x + 92y

Step-by-step explanation:

Set up the problem like this and combine like terms:

    40x + 58y

   - 7x  + 34y

--------------------

    33x + 92y

Or, set up the problem like this and combine like terms:

(40x + 58y) + (-7x + 34y)

40x + 58y - 7x + 34y

40x - 7x + 58y + 34y

33x + 92y

You should get the same answer with either method.

Six times the number of cattle less 87 is 999
AveGali [126]
You have to translate the statement into a mathematical expression...

Six times the number of cattle, if we let c be the number of cattle is:

6c

Less 87 means to subtract 87 so

6c-87

is 999 means

=999

so all together we have:

6c-87=999  now we need to isolate the variable by itself on one side of the equal sign....

6c-87=999  add 87 to both sides

6c=1086  divide both sides by 6

c=181

So there are 181 cattle.
