Let me see if I am correct I will get back to u
I: 2x+y=5
II:3x+2y=4
start by eliminating y
-2*I: -4x-2y=-10
II: 3x+2y=4
add both equations together
-2*I+II: -4x-2y+3x+2y=-10+4
-1x=-6
x=6
insert x=6 into I:
2*6+y=5
y=5-12
y=-7
so the solution is x=6, y=-7
B I’m pretty sure it’s that
Answer:

Step-by-step explanation:
Given
The above data
Required
The class width
To do this, we simply calculate the difference between the class limits of any one of the classes.
Taking 1187–1246 as a point of reference, the class width is:


102 would be the most reasonable estimate.
The experimental probability of owning fewer than 2 vehicles, based on the survey, is 15/50. We multiply this probability by the number of subscribers to the magazine:
15/50(340) = 102
