Answer:
26
Step-by-step explanation:
8/2 first and 24 - 4 + 6 = 26
The sum of tax and discount will given by:
(15+7.25)%
=22.25%
Total percentage of the total cost will be:
100+22.25%=122.25%
the selling price of the court will be:
122.25/100×275
=4336.187
The answer is 4336.20
(3 - 2i)(3 + 2i) . Its form is (a - b)(a + b) = a² - b²
( a = 3 and b = 2i)
(3)² - (2i)²
= 9 - (4i²) , but 1² = -1
= 9 - (-4) = 9+4 = 13
So (3-2i)(3+2i) = 13
Answer:
Step-by-step explanation:
P = pigs D = ducks
P + D = 17
P = 17 – D
4P + 2D = 50 because pigs have 4 feet
and ducks have 2 feet.
4(17 – D) + 2D = 50
68 – 4D + 2D = 50
.68 – 2D = 50
–2D = –18
D = 9
P = 17 – D
P = 17 – 9
9 = 17 – D
D = 8
