Answer:I think the answer is d.25
Step-by-step explanation:
General rule for multiplication or division between 2 numbers:
if you multiply or divide by:
1. same signs, answer is postive
2. different signs, answer is negative
so we have a -12 and a +9.9 so the answer is negative
then you divide 12 by 9.9
so the answer is negatiive, remember that
then divide as if positive
do
12/9.9
multiply by 10/10
120/99
simplify
120/99
factor out the 3/3
40/33
do the division (you can use calculator)
1.212121212121212121212121212
then it is negative so
-1.212121

Formula
Answer:
x = 90
Step-by-step explanation:
First, you'll want to take the three equations you see and set them up in an addition equation to add up to 360 like so...
- 4x + 2y + x + 2y - x = 360
Since two opposites add up to zero, they can be removed from the equation, therefore, removing (+ x) and (- x) from this equation:
Collect like terms (2y and + 2y):
Move the variable (+ 4y) to the right hand side of the equation and change its sign:
Divide both sides of the equation by 4.
x = 90 - y
Ignore the i y and you got your answer. x = 90. Hope this helped!
5(x+(x+1)+(x+2))=150
5(3x+3)=150
15x+15=150
15x=135
x=9
Your three consecutive integers are 9, 10, and 11.
