Answer:
Lebeled Price of watch = Rs. 2000
Selling price pf the watch = Rs. 1600
Step-by-step explanation:
- ∴ S = L - 20% L
- ∴ S = 0.8 L ..... (1)
- ∴ S = P + (1/3)P
- ∴ S = (4/3) P ..... (2)
- As we know, P = 1200
- ∴ S (4/3) × 1200
- ∴ S = Rs. 1600
- 1600 = 0.8L
- ∴ L = 1600 ÷ 0.8
- ∴ L = Rs.2000
- ∴ Lebeled Price of watch = Rs. 2000
- Selling price pf the watch = Rs. 1600
<span>x2 − 7x + 18
is prime
there is no way you can make two numbers multiply to get positive 18 and add to get negative 7
</span><span>(x − 9)(x − 2) = x^2 - 11x + 18
(x − 9)(x + 2) = x^2 -7x - 18
(x + 9)(x + 2) = x^2 +11x + 18</span>
Answer:
-1 and -2, or 9 and 10
Step-by-step explanation:
If x is the smaller integer:
x (x + 1) = 14 + 4 (x + x + 1)
x² + x = 14 + 4 (2x + 1)
x² + x = 14 + 8x + 4
x² − 7x − 18 = 0
Factor using AC method:
(x − 9) (x + 2) = 0
x = -2 or 9
x is the smaller integer, so the larger integers are -1 and 10. Check each pair of solutions.
-1 and -2:
(-2) (-1) = 14 + 4 (-2 + -1)
2 = 14 + 4 (-3)
2 = 2
9 and 10:
(9) (10) = 14 + 4 (9 + 10)
90 = 14 + 4 (19)
90 = 90
Both solutions work.
Answer:
x+6<12
Step-by-step explanation:
Since it is going left from 6, we know that x must be less than 6
