1. “Which one doesn’t belong?”

2. “ Sago in Jar”

In figure 1, each jar has the same number of sago inside. How many sago are in each box?

Indentyfy the equation that does not belong with the other three. Explain your reasoning?

(a) S + 14 = 27(b) 12 + s = 25(c) S – 16 = 29(d) S – 4 = 9

The answer is (c) because s = 45, it must be s = 13 and (a), (b), (d) satisfies the equations

Explain your answer!

Step 1: remove 2 jars of sago from each side. This leaves 1 jar and 2 sago on the left and 8 sago on the right.

Step 2: remove 2 sago from each side. This leaves 1 jar on the left and 6 sago on the right.

Thus, 1 jar contains 6 sago.

4. LENGTH OF SHARK

a Shirt Rp 55.000,-

When Disna pays for the shirt plus tax with Rp 100.000,- , She recieves Rp 50.500 .Find equation represent this situation if t is the tax on the shirt?

Tax is an amount of money added to the cost of an item. The amount you pay minus your change is what the item costs.

So, the equation is:

55.000+t=100.000−50.500

555.000 + t = 100.000 – 50.500

There are three kinds of shark at the shark aquarium in Sea world Ancol such as Leopark Shark, Bombo Shark, and Coral Catshark. They have a total lenght 670 cm.

The Leopark lenght 13 of the lenght of the

Bambo shark. The Coral catshark shark length 270 cm more than Leopark shark. How much does different length of Bambo shark and Coral catshark?

Before we determine the different length of bambo shark and coral catshark we must find the length of the three kinds of shark. Let, x = the length of Leopark shark3 x = the length of Bambo sharkx+270= the length of Coral cat shark.We get: ( x )+(3 x)+ ( x+270 )=670So, x=80The length of Bambo Shark is 240 cm and Coral cat shark is 350 cm.the diferencess between Bambo shark and coral cat shark is 110cm.

5. “International Trevelers”

The table shows the results of a survey given to 500 International travellers. Based on the data, which statement about international travellers is true? Explain your reasoning.

Vacation PlansDestination PercentsThe tropics 33

Europe 18Asia 19

Other 21No vacation 9

A Fifty have no vacation plans B Fifteen are going to AsiaC One sixth are going to the tropicsD Ninety are going to Europe

6. “Selling the book”

Two students, Farida and Dewi, decide to raise money y selling second hand Mathematics and Physics books to other students. They sold a total of 27 books for $100. If the Mathematics books were sold for $ 3 each and the Physics books were sold for $ 4 each, how many of each book did they sell?

Define:Let xbe the number of Mathematics books The number of Physics books is 27−x.Construct Income from Mathematics books + Income from physics books = total income

3 x+4 x (27−x )=100Solve :

3 x+108−4 x=100−x=−8x=8

Mathematics books, 8Physics books, 27 – 8 = 8Answer : They sold 8 Mathematics books and 19 physics books.

We must check that :The trevelers of the tropics is 33% x 500 = 165 The trevelers of the Europe is 18% x 500 = 90The trevelers of the Asia is 19% x 500 = 95 The trevelers of the otrher is 21% x 500 = 105 The trevelers of the no vacation is 9% x 500 = 45The statement thats true is D (Ninety are going to Europe)
