Answer:
C is the answer ,got it right on EDG 2020
Step-by-step explanation:
Answer: What you must do for this case is to graph each of the ordered pairs that you have in the table to obtain the dispersion chart. Note that in your table you have eight ordered pairs, therefore, your scatter chart must have eight pairs.
20%=8
10%=?
by cross multiplications,
10×8=80
80÷20=4
Hence the answer is 4.
Answer: 102,400,000,000,000,000,000
First do 20^10 = 10,240,000,000,000.
Then, multiply 10,240,000,000,000 * 10,000,000 to get 102,400,000,000,000,000,000.

7x - 18 = 10x + 3
Subtract 7x from each side
7x-7x - 18 = 10x-7x + 3
-18 = 3x+3
Subtract 3 from each side
-18-3 = 3x
-21 = 3x
Divide by 3
-21/3 =3x/3
-7=x
