Answer:
No solution
Step-by-step explanation:
Given equation is,
if x ≠ ±1
[Squaring on both the sides of the equation]
4 = (1 - x)(4 + x)
4 = 4 - 4x + x - x²
0 = -3x - x²
x² + 3x = 0
x(x + 3) = 0
x = 0, -3
But both the solutions x = 0 and x = -3 are extraneous solutions, given equation has no solution.
Answer:
1)
Ratio is 1:1.
2)
The required number is:
Step-by-step explanation:
1)
Let us consider that Cecilia's has a total of 'x' CDs
and let 'y' represent the number of Jazz CDs.
Now we are given information that:
1/5 of her Jazz CDs represents 1/10 of all her CDs.
i.e.
i.e. the Jazz CDs are half of the total CDs.
Hence, the number of Non-Jazz CDs(z)
=
Hence, the ratio of Jazz to Non-Jazz CDs
Hence, the required Ratio is 1:1.
2)
How would you change to a number times 25?
We will find the number by dividing the quantity by 25 to find the required number.
i.e.
Hence the required number is:
Answer:
4 1/2
Step-by-step explanation:
2 1/3 pounds and 2 1/6 pounds
convert the 1/3 pounds into x/6 by multiplying both numerator and denominator by 2 which equals 2/6
Then add 2+2 which gives 4 and the 1/6 and 2/6 which is equal to 3/6 which simplifies into 1/2.
4 1/2
Answer:
16 servings
Step-by-step explanation:
5 cups per 10 servings = 0.5 cups per serving
1 quart = 4 cups so 2 quarts = 8 cups
8 cups / 0.5 cups per serving = 16 servings
