4:3 for 21 balloons is essentially
4x + 3x = 21
7x = 21
x = 3
We can multiply 4 and 3:
4*3 = 12
Kali had 12 blue balloons at her party
Answer:let us compare the following pairs of power of 10,9×10^6 ÷3×10^12=3×10^-6
Step-by-step explanation:
Comparing pairs of power of 10 involve applying principle of indices.in what is known as the laws of indices
Law1 states that X^a ×X^b=X^(a+b) meaning that multiplication of indices results to addition of the indexes raise as exponenet of 10, similarly a division as in the answer above always lead to substraction of the indexes as seen in the example 9×10^6/3×10^12 will becomen9÷3×10^(6-12)=3×10^-6.
Answer:
The answer is 9x + 18
