Answer: its either "10" or "70"
Answer:
Step-by-step explanation:
Cost of 1 kg of Potatoes = $ 2
Cost of 1 kg of Carrots = $ 2.40
Let the cost of 1 kg of Potatoes = x
Let the cost of 1 kg of Carrots = y
ATQ , 8x + 5y = 28 - 1)
2x + 3y = 11.20 - 2)
Multiplying 2) by 4
8x + 12y = 44.80 - 3)
Applying Elimination method in 1) and 3)
8x + 5y = 28.00
8x + 12y = 44.80
0 + -7y = - 16.80
y = 16.8/7
y = 2.4
Putting the value of "y" in 1)
8x + 5(2.4) = 28
8x + 12 = 28
8x = 16
x = 16/8
x = 2
Answer:
5x^5
Step-by-step explanation:
45x^7 ÷ 9x^2=45÷9 × x^7÷x^2= 5x^5
Answer:
16
Step-by-step explanation:
tan^-1 (2.1/ 7.2) = 16 .26...
The answer is 34.25
You must divide it like a regular problem because a negative divided by a negative is a positive
