Answer: 13kg potatoes=9.36 2.5 of carrots=155p
Step-by-step explanation:
potatoes 5kg=3.6 carrots .5kg=31p
value of each kg of potatoes is...
so
value of each kg of carrots is...
31x2=62
so (I assumed when you typed 21/2 it meant 2 1/2 or 2.5)
2.5x62=155
So since x= sand bags replace x with 0 so 7y=105 is left divide by 7 and you get y=15 so 15 bags
Answer:
The width of the foil = w = 2.5 inches
Step-by-step explanation:
We know that the Area of a rectangular piece:
Here:
Given that area of the rectangular piece of foil:
Area = A = 11 1/4 square inches
= 45/4 square inches
= 11.25 square inches
Length = l = 4 1/2 inches
= 9/2 inches
= 4.5 inches
Using the Area formula
inches
Thus, the width of the foil = w = 2.5 inches
Answer:
1 3/14
Step-by-step explanation:
You divide everything by 2 because it is a fraction.
Answer:
x³ - 3x² - 9x + 27
= x²(x - 3) - 9(x - 3)
= (x² - 9)(x - 3)
= (x -3)(x + 3)(x - 3)
= (x + 3)(x - 3)²
