Solve for zzz. 42=-7(z-3)42=−7(z−3)
xxTIMURxx [149]

Answer:

False

Step-by-step explanation:

Well to solve for z we single it out, distribute, use the communicative property, and combine like terms.

42 = -7(z - 3)42 = -7(z - 3)

Distribute

42 = -7z + 21*42 = -7z + 21

42 = -7z + 882 = -7z + 21

-42 to both sides

-7z + 840 = -7z + 21

-21 to both sides

-7z + 819 = -7z

+7z to both sides

819 = 0

<em>Thus, </em>

<em>the given equation is false.</em>

<em>I hope this helps :)</em>

It will cost $73 perhour to rent a sailboat and $88 to rent a ski boat.how much more will it cost to rent a ski boat than a sail
seraphim [82]
Well we want to find out how much more will it cost to rent a ski boat than a sailboat for four hours. 

All we have to do is Multiply 73 by 4 for the sailboat which gives you $292 

Now we do the same for the ski boat. $88 * 4 = $352 

So we now have to find out how much more it will cost for a ski boat than a sail boat. All we do is subtract 352 by 292 

352
