Answer:
(2, - 1 )
Step-by-step explanation:
2x + y = 3 → (1)
x - y = 3 → (2)
adding the 2 equations term by term will eliminate y
3x + 0 = 6
3x = 6 ( divide both sides by 3 )
x = 2
substitute x = 2 into either of the 2 equations and solve for y
substituting into (1)
2(2) + y = 3
4 + y = 3 ( subtract 4 from both sides )
y = - 1
solution is (2, - 1 )
The measure of the angles would be: m<b=12 and m<e=12.
I would say the object will float because the density of water is 999.99kg/m which is slightly less than 1g but still more than the object.
Answer:
Step-by-step explanation:
3x-2y=24......eqi
x+2y=48........eqii
now solving eq i&ii
4x=72
x=72/4
x=18
now putting the value of x in eqii
18+2y=48
2y=48-18
y=30/2
y=15
