Answer:
First equation x=2, Y=9, Second Eq, x=2, y=1
Step-by-step explanation:
X+Y=11
2X-Y=-5 by substitution Y=11-X
So, 2x-(11-x)=-5, 2x-11+x=-5, 3x=6, x=2. Thus, Y=11-2=9
2x+y=5
3x-2y=4
so, y=5-2x
Thus, 3x-2(5-2x)=4
3x-10+4x=4, 7x=14, x=2, Thus, Y=5-2(2)= 1
Answer:
you in jacksonville
Step-by-step explanation:
Cross multiply.
75 / x = 25 / 35
25x = 35(75)
25x = 2625
/25 /25
x = 105
Therefore 105 students liked skating.
Proof:
105 + 35 = 140.
140 * 0.75 = 105
140 * 0.25 = 35
140 (total) split into quarters.
35 + 35 + 35 + 35 = 140
35 + 35 + 35 = 105 (3 quarters liked)
35 = 35 (1 quarter disliked)
The amount of electricity required to run the manufacturing operations and lighting is given by: y = 12 x + 24.
When no parts are manufactured : x o= 0.
y o = 12 * 0 + 24
y o = 24
Answer:
( x o, y o ) = ( 0, 24 )
When no parts are manufactured, 24 watts is used ( only for lighting the facility ).
