(A) 5a +10b -36
(B) 19p + 921
(C) -4a +7b
(D) 7x -9y + 10z
Answer:
a^3 (a^4) = a^7
(2a)(5ab) = 10a^2b
Step-by-step explanation:
1. you have to figure out what 3/4 of Ella's time is.

(You find that out by multiplying 5x1. Then add 3.)
2. Convert the fractions into decimals. (This will help make it easier when dividing.)


3. Next you are going to divide 1.6 by .75

4. Now multiple 2.13 by 5.

Answer is 10
Answer: 2
Step-by-step explanation:
Recall from the laws of Logarithms:
Log a - Log b = Log ( a/b )
That means
Log 200 - Log 2 = Log ( 200/2)
= Log 100 , which could be written as
Log 
Recall from laws of Logarithms:
Log
= b Log a
Therefore:
Log
= 2 Log 10
Also from law of Logarithm
Log 10 = 1
Therefore 2 Log 10 = 2 x 1
= 2
Answer:
When X=Y every number on either side is the same, for example 1(X)=1(Y)
Step-by-step explanation:
This is because when X=Y the X value isn't altered in any way to equal Y, so they are the same number, hope this helped!
