Answer:
The equations whose solutions are -1/2 are:
1. 4x + 1 = 6x + 2
2. 3x + 7 = 5x + 8
Step-by-step explanation:
Using the digits 0 to 9 at most one time each, the equations whose solutions are -1/2 are:
1. 4x + 1 = 6x + 2
-2x = 1
x = -1/2
2. 3x + 7 = 5x + 8
-2x = 1
x = -1/2

Answer:
<u>v = √(LT/m)</u>
Step-by-step explanation:
Given :
Multiply both sides with L :
- T × L = mv²/L x L
- LT = mv²
Divide both sides by m :
- LT × 1/m = mv² × 1/m
- LT/m = v²
Take the square root on each side :
- √v² = √(LT/m)
- <u>v = √(LT/m)</u>
When drawn out, the answer becomes the sum of the bases of two triangles
Answer: 70 m
