Answer:
$9
Step-by-step explanation:
Given I owe my friend $16 and my mom owes me $25
step 1-->take back money from mom
Mom gives back you $25
Now you have $25
Step 2: return the money you owe to friend
you owe $16
You have $25 and return $16
Thus , money you will have = money you have - money you return
money you have = $25 - $16 = $9
Thus, you will have $9 , after all is settled.
Answer:
=- , =
Step-by-step explanation:
3-4=2
3=2+4
3=6 (divide both sides by 3)
=2 (simplify)
x=±
R + g + b = 50
r = b + 6
g = b - 4
(b + 6) + (b - 4) + b = 50
3b + 2 = 50
3b = 50 - 2
3b = 48
b = 48/3
b = 16 <=== 16 blue marbles
r = b + 6
r = 16 + 6
r = 22 <=== 22 red marbles
g = b - 4
g = 16 - 4
g = 12 <=== 12 green marbles
Set side lengths equal to each other and solve for x. All sides are equal lengths in a square.
6x - 1 = 4x + 6
2x = 7
X = 3.5
Plug in x in one of the equations
4 x 3.5 + 6 = 20
Each side is 20 cm
