1. Ms. Enigma said, " Five less than one third of my age is 14." How old is Ms. Enigma?

x-5, 1/3 x---> x/3 x/3 -5=14 let x= Ms. Enigma's age.
+5 +5 Substitute to check...
x/3=19 x/3 -5=14
x3 x3 57/3 -5=14
x=57 19-5=14
14=14 Ms. Enigma is 57.

2. Suppose you have \$50 and earn \$8 per hour. How many hours must you work until you have \$170?

8x+50=170 Let x = hours of work
-50 -50 Substitute to check...
8x=170 8x+50=170
/8 /8 8(15)+50=170
x=15 170=170 I must work 15 hours.

3. Valley Vudei charges a \$12 annual fee plus \$3 per movie for rentals. Last year., Jennifer spent \$90 at the store. How many movis did she rent?

3x+12=90 Let x = # of rented movies
-12 -12 Substitute to check...
3x=78 3x+12=90
/3 /3 3(26)+12=90
x=26 90=90 Jennifer rented 90 movies.

4. Kimo's car needed work. The mechanic charged him \$130 for parts plus \$40 per hour for labour. If the bill totaled \$270, how many movies did she rent?

40x+130=270 Let x = hours of labour required

-130 -130 Substitute to check...
40x=270 40x+130=270
/40 /40 40(3.5)+130=270
x=3.5 270=270 Kimo will labor 3.5 hours.
5. Suppose you are a salesperson for Quark Computer company. Each month you earn \$400 plus one sixth of your sales. What amount must you sell this month to earn \$2000?

1/6 x-->x/6 x/6+400=2000 let x = amount I must sell
-400 -400 Substitute to check...
x/6=1600 x/6 + 400=2000
x6 x6 9600/6 + 400 =2000
x=9600 2000=2000 I must sell 9600.

Today in class, we were given a worksheet for homework. On one side, there are eight geometry questions. Here are the first four of these questions:

1. The length of a rectangle is 3 times the width. The perimeter id 96cm. Find the width and length.

2. The length of a rectangle is 5m greater than the width. The perimeter is 150m. Find the width and length.

3. The width of a rectangle is 12 cm less than the length. The perimeter is 156cm. Find the width and length.

4. The length of a rectangle is 2cm less than 7 times the width. The perimeter is 60cm. Find the width and length.

BUT WAIT!!

Before you attempt to solve these questions, take a look at the slide show beneath. It tells you 7 Steps to Solving the questions. It should make solving easier for you.

And now back to the questions.

1. The length of a rectangle is 3 times the width. The perimeter id 96cm. Find the width and length.

2. The length of a rectangle is 5m greater than the width. The perimeter is 150m. Find the width and length.

3. The width of a rectangle is 12 cm less than the length. The perimeter is 156cm. Find the width and length.

4. The length of a rectangle is 2cm less than 7 times the width. The perimeter is 60cm. Find the width and length.

For question 4 I got it wrong because I was supposed to put decreased and not less than.
For question 6 I got it wrong because I was supposed to put the 7 infront of 4x
So as you can see I would have gotten it right if only I wrote them opposite from each other.

I got write the algebriac expression or equation for the pattern you notice wrong because I rushed and The answer on the very right lower corner isn't even understandable.

My T-Chart has the (x) axis on the left and the (y) axis on the right because that is the order it has to be in.
