= 20y + 3y -4(-2y)
= 20y + 3y + 8y
= 31y
In short, Your Final Answer would be 31y
Hope this helps!
Answer:
Length: 25
Step-by-step explanation:
the ratio we use is 5:1
125÷5=25
5 is the width and 25 is the length
to check the answer find the area with those measurements
5x25=125 so its correct
Answer is D 2.75,-2.5,-2.25
Whats the question ? Are you trying to figure out how much he has left ?
Answer:
Step-by-step explanation:
Given system is-
-2x+2y+3z=0 -------------(1)
-2x-y+z=-3 ----------------(2)
2x+3y+3z=5 --------------(3)
From (1)-(2) we get
3y+2z=3 ----------------(4)
Again from (2)+(3),
2y+4z=2 ----------------(5)
Now multiplying equation (4) by -2
-6y-4z=-6 --------------(6)
Adding (5) and (6)
-4y=-4
dividing by -4
y=-4 / -4
=1
So, y=1 ,
using y=1 in (5)
2(1)+4z=2
or, 2+4z=2
or, 4z=2-2
or, 4z=0
or, z=0
using y=1 and z=0 in (3)
2x+3(1)+3(0)=5
or, 2x+3+0=5
or, 2x=5-3
or, 2x=2
or, x=2/2
=1
So, the solution is-
(x,y,z)=(1 , 1 , 0)
