Someone answer i've ask this question 4 times and no one answers me.
things to do for #1-2:
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. –3g + 2  

2. –4λ – 4

Step-by-step explanation:

1. Given data: –7g and 4g + 2

Now, let us find the sum of –7g and 4g + 2.

Sum of –7g and 4g + 2 = (–7g) + (4g + 2)

                                      = –7g + 4g + 2

                                      = –3g  + 2

2. Given data: 6λ and 2λ – 4

Now, let us find the difference when 6λ is subtracted from 2λ – 4.

6λ subtracted from (2λ – 4) = (2λ – 4) – 6λ

                                             = 2λ – 4 – 6λ

                                             = –4λ – 4

Hence the sum of –7g and 4g + 2 is –3g + 2 and the difference when 6λ  is subtracted from 2λ – 4 is –4λ – 4.

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1
