It’s d bec each x has one input
No, 600 mm is less that 5 m
1 meter = 1000 millimeters
That means that to find out how many millimeters are in 5 m, one way you could calculate it is by multiplying 5 by 1000
5 • 1000 = 5000, so 5 m = 5000. Since 600 < 5000, 600 mm < 5 m
2x + 3y = 1
y = 3x + 15
Get the same variables on each side
3y = 1 - 2x
y = 15 + 3x
Multiply both sides of that second equation by 3 so we can subtract.
3y = 1 - 2x
3y = 45 + 9x
Subtract the equations from each other.
0 = -44 - 11x
Solve.
44 = -11x
-4 = x
Use x in an earlier equation to find y.
y = 3x + 15
y = 3 * -4 +15
y = -12 + 15
y = 3
x = -4, y = 3
The answer is D) none of the above
Answer:
no
Step-by-step explanation:
The sum of the angles of a triangle must add to 180 degrees
115+55+20 = 190
This is not equal to 180 so it is not a triangle.
