Answer:

4. 6 cups

6. 50 dollars

7. 27000 words

8. 300 dollars

Step-by-step explanation:

2 cups x cups

-------------- = -----------

6 people 18 people

Using cross products

2 * 18 = 6x

Divide by 6

36/6 =6x/6

6 =x

12 cans 30 cans

-------------- = -----------

20 dollars x dollars

Using cross products

12x = 20*30

12x = 600

Divide by 12

12x/12 =600/12

x = 50

3 hours = 3*60 minutes/hour = 180 minutes

30 minutes 180 minutes

-------------- = -----------

4500 words x words

Using cross products

30x = 4500*180

Divide by 30

x = 4500*180/30

x=27000

45 dollars x dollars

-------------- = -----------

15 burgers 100 burgers

Using cross products

45*100 = 15x

Divide by 15

45*100/15 = x

300 =x

2/3(x-2)=-2<br>how would I solve this

xeze [42]

Answer:

x =(5/3)

Step-by-step explanation:

The given expression is $\frac{2}{3(x-2)} = -2$

Now to simplify it,

The first step is to cross multiply.

So, the expression becomes

$\frac{2}{(-2)} = 3(x-2)$

or, -1 = 3x - 6

⇒ 3x = -1 + 6

⇒ 3x = 5 , or x =(5/3)

Convert 0.50 sen /g to RM/kg

IgorC [24]

the conversion is:

0.50 sen /g = 5 RM/kg

<h3>How to change the units?</h3>

First, we know that

1sen = 0.01RM

Then we can change:

0.50 sen /g = 0.50*(0.01 RM) /g = 0.005 RM/g

Now we use the relation:

1g = 0.001kg

So we can rewrite:

0.005 RM/g = 0.005 RM/(0.001kg) = 5 RM/kg

So the conversion is:

0.50 sen /g = 5 RM/kg
