Scibe Post For June 5, 2006

In class today we looked through some of our worksheets in our duotang and answered the questions. We answered the questions because on the test, there are some similar questions.

18) Using the equation 2x+1=y, create a table of values where x equals 2, 3, 5, 7, and 8.


19)Complete the table

8)What does n equal in the diagram below?
4 diamonds(n)=32
(n)=32/4 n=8

9)What does n equal in the diagram below?

n/3=8x3
x3
n=24

2)Six friends are going to equally share a sum of money. Each friend will receive $9.76. Write an equation which shows the original sum of money.
n=(9.76)x6

3)Write an equation to show "sixty by a number equals three".
60/n=3

4)When a number is added to twelve, the sum is seventeen. Write this equation.
12+n=17

5)Express 4n=14
Four multipled by a number equals 14.

6)Using the table above, when did the temperature rise the most?


85-30=55 According to the table, the temperature rose the most between 0 to 5 minutes.
130-85=45
155-130=25
170-155=15

7)Predict the temperature of the oven at the 12 minute mark.
25/5=5 degrees celcius 130+5+5=140

8)What algebraic expression would explain the relationship between Bob's and Doug's pens?
B=Bob's pens D=Doug's pens
B=2D-2 B/2+1=D

9)a)How many pens would Doug have if Bob had 16 pens.
16/2+1=9
b)If Doug had 10 pens, how many would Bob have?
2(10)-2=18

Remember that the rule has to work out with all the possibilities or else it won't work.

Lastly, we watched a brain-pop video on solving equations.
