Answer:
47/5 or 9 2/5
Step-by-step explanation:
12/1-13/5
60-13/5
=47/5
1/x + 1/y = 8
x + y = 8
6/x + 12/y = 72n
X² + 2x +3
If the discriminent Δ = b²-4.a.c <0 , that means the roots (or the zero value) are nit REAL Number (they are imaginary or complex)
Δ = 2² - 4(1)3) = 4 - 12 = -8
since Δ = - 8 < 0 there are no real roots
The rectangular form is 3c/30=z
Z=10 3c//30
10z+70x + 17x-10z
The original price was $70.2. (If it’s not supposed to have cents then it’s just $70).
This is because you convert 35% to 1.35. Then, you multiply 52 by 1.35. That’ll give you 70.2.
