Answer:
3 markers. The equation is 15-3x.
Step-by-step explanation
You multiply the number of friends by the number of markers and then subtract from 15. You create the equation by taking the original number of markers you had and subtract it from 3 times whatever number.
Okay first
22x+11=5x-7
You need to move the variables so it eaquals 0
22x+11-5x+7=0
Now combine like terms
17x+18=0
Move 18 over to divide
17x=-18
X= -1.1 or just -1
Good luck! :D
So 5^2 -4^2 is 25-16 which is 9
6^2/9 is 36/9 which is 4 +9 is 13
13(13) is 169
Answer:
<h2>22ft</h2>
Step-by-step explanation:
Step one:
given that the orientation of the garden is a triangular shape(it has three sides)
the perimeter is given as=46ft
one side y=11ft
the second side z= 13ft
let the third side be xft
Step two:
the expression for the perimeter = z+y+x
46=11+13+x
46=24+x
solve for x
x=46-24
x=22ft
Therefore the third side is 22ft long
