Answer:
The two such fractions are: 113/100 and -22/25.
Step-by-step explanation:
Let us assume two such fractions are P and Q.
⇒ P x Q = -1
and P + Q = 1/4
Now, to solve for the values of P and Q:
P + Q = 1/4 ⇔ Q = 1/4 - P
Substitute this value of Q in P x Q = -1, we get:
P x Q = -1
Now, solving this with the help of QUADRATIC Formula:
We get: P = 1.13 or P = -0.8825
Now, if P = 1.13, Q = -1/1.13 = -0.88 = -88/100 = -22/25
If P = -0.88, then Q = 1/0.88 = 1.13 = 113/100
Hence, The two such fractions are: 113/100 and -22/25.
Answer:
Brand A: $0.05
Brand B: $0.07
Brand A is the better buy
Step-by-step explanation:
Brand A: 72x = 3.89
Brand B: 96x = 6.62
Brand A:
72x = 3.89
/72 /72
x = $0.05 (this one is the better buy)
Brand B:
96x = 6.62
/96 /96
x = $0.07
Hope this helps!
