4x+4=-3+2x+15
Step 1: combine like terms
4x-2x=15-3-4
2x=8
Step 2: divide by 2 on both sides
x=4
Its the first One i think
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:
12%
Step-by-step explanation:
21/175 = ?/100%
21/175 = 12%/100%
Hey! Did you ever figure out the answer? I am stuck on this one as well!
