Answer:
-3
Step-by-step explanation:
first distribute 5 to x and 2 =5x+10 then combine like terms to 5x+4x=9x so on one side u have 9x+10 then on the other side of the equation u have 6x+1 now get the whole numbers on one side of the equation and variables on the other.
9x+10=6x+1
-6x -6x
3x+10=1
-10. -10
<u>3x</u>=<u>-9</u>
3. 3
-3=x

Answer:
Here is a generic way to set up this type of algebra problem.
d = total amount of dirt at the site (tons)
r = rate or removal (tons/hr)
t = time it takes to remove all of the dirt (hr)
d = rt
The total amount of dirt equals the removal rate times hours spent removing all the dirt.
Since you want to solve for t, divide both sides by r
t = d/r
Answer:
3x^2+27y^2-18xy
Step-by-step explanation:
3(x-3y)^2
3 [(x-3y)(x-3y)]
3 [x^2-3xy-3xy+9y^2]
3 [x^2-6xy+9y^2]
open d bracket
3x^2-18xy+27y^2
rearrange
3x^2+27y^2-18xy
Answer:
Step-by-step explanation:
First, you need to find the fraction of the passengers who are not senior citizens. Add 1/5 and 2/3 to get 13/15.
This means that 13/15 of the passengers aren't senior citizens and 2/15 of the passengers are senior citizens.
