Answer:

Option B : 38/2 is the correct answer.

Step-by-step explanation:

Given that:

Distance to travel = 38 miles

Speed of object = 2 miles per hour

Distance = Speed * Time

To find the time, we will divide the distance by speed.

Time = $\frac{Distance}{Speed}$

Putting values of distance and speed in the formula.

Time = 38/2

Hence,

Option B : 38/2 is the correct answer.

The sum of three numbers is 3. if the second number is subtracted from the sum of the first and third numbers, the result is 9.

Margaret [11]

Let the three numbers be x, y, and z.

If the sum of the three numbers is 3, then x+y+z=3

If subtracting the second number from the sum of the first and third numbers gives 9, then x+z-y=9

If subtracting the third number from the sum of the first and second numbers gives -5, then x+y-z=-5

This forms the system of equations:
[1] x+y+z=3
[2] x-y+z=9
[3] x+y-z=-5

First, to find y, let's take do [1]-[2]:
x+y+z=3
-x+y-z=-9
2y=-6
y=-3

Then, to find z, let's do [1]-[3]:
x+y+z=3
-x+-y+z=5
2z=8
z=4

Now that you have y and z, plug them into [1] to find x:
x+y+z=3
x-3+4=3
x=2

So the three numbers are 2,-3, and 4.

I believe you did it correctly but over the wrong line. You were supposed to do it over line M and it looks like you did it over the X-axis.
