Let the original price = x
then 76.50 = 0.90x
x = 76.50 / 0.90 = 85
1/6+2/3+1/4
First find the highest common multiple of the denominators=12
Then multiply each term by the quotient of 12/denominator
So...it becomes 2/12+8/12+3/12
Add all the numerators and keep the denominator constant
It becomes (2+8+3)/12=13/12
=1 1/12
A squared plus b squared equals c squared. 5 squared is 25. 2 squared is 4. 25 plus 4 is 29. The square root of 29 is 5.385. Therefore, x=5.385. The equation for this would be •square root symbol• (25+4).
Answer: the two numbers are 7 and -27
Step-by-step explanation:
Let the two numbers be a and b
From the question,
a + b = -27.......eqn 1
a - b = 41............eqn 2
Sum the two equations
2a = 14
Divide both sides by 2
a = 14/2; a = 7
Substitute a = 7 into equation 2
a - b = 41
7 - b = 41
Make b the subject of the equation
-b = 41 -7
-b = 34
b = -34
Check:
a + b = -27, slot the values of a and b
7 + (-34) = -27
7- 34 = -27
I hope this is clear, please mark as brainliest answer
