Step-by-step explanation:
(a + b)² = 9
(b + c)² = 25
(a + c)² = 81
Taking the square root:
a + b = ±3
b + c = ±5
a + c = ±9
By adding these three equations together and dividing both sides by 2, we get the value of a + b + c.
Possible combinations for a + b + c such that the sum is greater than or equal to 1 are:
a + b + c = (-3 + 5 + 9)/2 = 11/2
a + b + c = (3 − 5 + 9)/2 = 7/2
a + b + c = (3 + 5 + 9)/2 = 17/2

so basacilly the answer to all of the question is a
Step-by-step explanation: you welcome!
Answer:
190 is 76% of 250
Step-by-step explanation:
We have, 76% × x = 190
Multiplying both sides by 100 and dividing both sides by 76,
we have x = 190 × 100/76
x = 250
If you are using a calculator, simply enter 190×100÷76, which will give you the answer.
