Answer:
2.3 ×
is 20,000 times greater than 1.15 ×
Step-by-step explanation:
Given as :
The first number= x = 2.3 × 
The second number= y = 1.15 × 
Let The first number is z times greater than second number
i.e x = z × y
Or, z = 
Or, z = 
Or, z = 2 × 
∴ z = 20,000
So,The first number is 20,000 times greater than second number
Hence, 2.3 ×
is 20,000 times greater than 1.15 ×

Answer:
A, 1:4
Step-by-step explanation:
15:60 simplified:
3:12
1:4
so twice as much is 2 times x and she did 10 more than that quantity.
10 + 2x
We assume that we need to simplify the expression in two different ways.
Answer:
One way: Raise both, the numerator and denominator, to the third power, and then simplify the expression.
Second way: Simplify the terms inside parentheses, and then raise the result to the third power.
The result of both ways is the same: 
Step-by-step explanation:
<em>One way</em>
Raise both, the numerator and denominator, to the third power, and then simplify the expression:





This is the first simplification.
<em>Second way</em>
Simplify the terms inside parentheses, and then raise the result to the third power.
