Answer:
X = 9
Step-by-step explanation:
<span>For a system of equations to have infinitely many solutions, the equations have to be lineary dependent, (i.e. one of the equations is a multiple of the other equation). For the given equation to have infinitely many solutions, the second equation have to be a multiple of the first equation.
The first equation can be rewritten as y - 2x = -5
The second equation is the first equation multiplied by 2, i.e. 2(y - 2x= -5) = 2y - 4x = -10
Therefore, the correct answer is -10 (option a).</span>
Answer:
6
Step-by-step explanation:
1/2 + 1/2 = 1
1/2 + 1/2 = 1
1/2 + 1/2 = 1
There are 6 halves that equal 3.
Another way to do this is:
1/2x = 3
3 / 1/2 = 6
x = 6
Answer:
630
Step-by-step explanation:
Answer:
15771 > - 7
Step-by-step explanation:
Comparing the elevation of the two points ;
Point with elevation of 15771 is positive meaning it occurs above sea level and this higher than the point with an elevation of - 7 which is occurring below sea level
Hence, to compare both elevations :
Montblanc has higher elevation than Rhone river delta
Montblanc elevation > Rhone river delta
15771 > - 7
