Answer 2

Hello @bob55555 and Welcome to OpenStudy!

to solve for r
we want to get r alone on one side

so let's try subtracting 16 from both sides first

16 + r/2 = -11
-16 -16
----------------
what would you get?

Answer 3

-32 and -5

Answer 4

not quite ^_^
we subtracted 16 to get ride of the original 16
16 - 16 = 0 right?
and -11 - 16 = -27

do you see how I got those numbers?

Answer 5

so thats the answer

Answer 6

is -27 the answer

Answer 7

Mle

Answer 8

not yet
we now have
r/2 = -27
but the 2 is still stuck to the r that we want

so we should multiply both sides by 2
(1/2) * 2 = 1
and (-27) * 2 = -54
so r = ^

Answer 9

whats the answer Mle

Answer 10

(1/2) * 2 = 1
and (-27) * 2 = -54
so r = ^

Answer 11

so its -54

Answer 12

that's right :)

Answer 13

Answer 15

What is the solution to this equation?
\large \mathbf{2(2-j) = 4(j + 10)}

j = _______

Answer 16

there it is

Answer 17

Mle

Answer 18

2(2-j) = 4(j + 10)

first we would use distributive property to multiply everything out
a(b - c) = ab - ac

so 2(2-j) = 4 - 2j

do you see how that works?

can you do 4(j + 10) = ?

Answer 19

idk

Answer 20

no i cant

Answer 21

ok
2(2 - j) became 2*2 - 2*j which is how it equals 4 - 2j

so for 4(j + 10) becomes 4*j + 4*10 = 4j + 40

so now we have 4 - 2j = 4j + 40

Answer 22

from there we can add 2j to both sides
4 - 2j = 4j + 40
+2j +2j
---------------- and get
4 = 6j + 40

then subtract 40 from both sides

4 = 6j + 40
-40 -40
------------- and get
-36 = 6j

6j = -36
all we have to do from there is to divide by 6

Answer 23

negative 36 divided by 6 = [answer]

Answer 24

6 right Mle

Answer 25

r = -54
