Question

Solve this linear equation for p:

2.6(5.5p – 12.4) = 127.92

1. Distributive property:

2. Addition property of equality:

3. Division property of equality:

4. Solution:

14.3p – 32.24 = 127.92

14.3p – 32.24 + 32.24 = 127.92 + 32.24

14.3p = 160.16

StartFraction 14.3 p Over 14.3 EndFraction equals StartFraction 160.16 Over 14.3 EndFraction.

p =

Answer 1

One question at a time

Do you know the distributive property?

It's really simple
a(b+c) = ab + ac
So we just multiply everything inside the parenthesis by a

So for example,
5(3x + 2)
= (5 * 3x) + (5*2)
=15x + 10

Answer 2

yeah i think i know the answer
is it
p+11.2

Answer 3

So now for your question, distribute the 2.6

Tell me what you get
2.6(5.5p - 12.4) = 127.92

another version of the distributive property is
a(b-c)
= ab - ac
So that minus sign stays

Answer 4

i think i know the answer to it

Answer 5

is it 11.2

Answer 6

Bingo, you got it!

Answer 7

ok now i have another one

Answer 8

Let's make another post for it :)

Answer 9

ok

Answer 10

Oh I didn't realize that was all your work in the question, I thought that was a whole separate question LOL
