Someone answer i've ask this question 3 times and no one answers me.

a. write an expression based on the given statement

b. simplify the expression you just wrote

1. find the sum of -7g and 4g + 2

2. find the difference when 6ん is subtracted from 2ん - 4

1 a)

1 b)    

2 a)

2 b)

Step-by-step explanation:

Given statements:

1. Find the sum of -7g and 4g + 2

2. Find the difference when 6 is subtracted from 2 - 4

a) To write an expression based on the given statement

b) To simplify the expression

Solution:

1) The expression for sum of and  is given as:

1 a)

The above expression can be simplified by combining the like terms:

1 b) ⇒       [ As ]

2) The expression for the  difference when is subtracted from can be given as:

2 a)

The above expression can be simplified by combining the like terms:

2 b) ⇒    [ As ]

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

idk
