Answer:
a = -5
Step-by-step explanation:
15 - a = 20
Move the constant of 15 to the other side by subtracting it.
-a = 5
Divide by -1 to make a positive.
a = -5
Check.
15 - (-5) = 20
15 + 5 = 20
20 = 20
Minus 3y both sides
2y-6=-20
add 6 to both sids
2y=-14
divide 2
y=-7
Answer: No triangles can be formed.
Step-by-step explanation: Given Dimensions = 15cm , 7cm , 5cm
Inequality property = Sum of 2 shorter sides ≥ 3rd side
∴ 7 + 5 is not greater than 15
∴<u><em> No triangles can be formed.</em></u>
