Janns Scribe Post

Sorry this scribe was waaay late

This scribe is about the algebra test 2.0 and ill tell you all about it and what the answers are!

This is part 1 of the test ill give you 3 possible answers for each one.

1) 2x-9 - 2 times a number decreased by 9
- twice a number decreased 9
- 2 groups of a numbers decreased by 9

2) 10-4x - 10 decreased by 4 times a number
- 10 decreased by 4 groups of a number
- 10 deminished by 4 sets of a number

3) 5(x-8) - 5 groups of the difference of a number and 8
- a number decreased by 8 times 5
- 5 times a number decreased by 8

4) 7(x+5) - 7 sets of the sum of a number and 5
- the sum of a number and 5 times 7
- a number combined with 5 times 7

This is part 2 of the test , there is only one answer possible for each
5) 6 centimeters more than two thirds of length X = 6 + 2/3 X
6) three times the sum of a number and 2 = 3(n+2)
7) nine decreased by 2 times a number = 9 - 2n
8) four less than five times a number = 5n - 4

This is the chart questions on the other page.

The following Graph shows the first 4 terms of a pattern

A) Create a Chart that shows the first 10 terms of the pattern



B) Write the algebraic Express for the relation ship between hours spent walking and the number of kilometres walked

- Hours x 4 -1 = Km walks
- 4x -1 = y
X = hours
Y= Km walked

C) Using your algebraic expression determine how far they could walk after 50 hours

50 = 4x - 1
= 4(200) - 1
= 199 Km

This test was out of 16. Thanks!
