Answer:
Each slice of bread costs $0.06.
Step-by-step explanation:
To find how much each slice of bread costs, you need to divide the cost (0.90) by how many slices there are (15). When you divide the two, you get 0.06. To check your answer you can do 0.06x15 and that will equal $0.90.
Answer:
width: 50 yards
length: 80 yards
Step-by-step explanation:
I would write an equation to start
x = width
260 = 2x + 2(x + 30)
260 = 4x + 60
200 = 4x
x = 50
Width = 50 yards
Length = width + 30
Length = 50 + 30
Length = 80 yards
Answer: 6
Step-by-step explanation:
From the prime factorization of 54 you get:
54 = 2×3×3×3
So ,
You can write it as,
54 = 2×3^2×3,
Make sure all of the factors are in square form, so we add a another 2 and a three to the factors to make them all in square form
You get
=2×3^2×3×2×3 (the last 2×3 is added because one 2 and 3 were not having another pair so they were added to make them squares)
So k is basically 2×3 which is 6
And 54×6 gives us 324, which is a perfect square.
