The first property is commutative ( the numbers 38 and 677 are swapped over)
Then we have the associative property ( where the paretheses are moved to get 38 and -38 together)
then the additive inverse ( 38 + (-38) = 0
and finally to get the 677 we use the additive identity property.
Step 1: move 64 to a left side, -13 - 64 = 7d
Step 2: -77 = 7d
Step 3:
= d
Step 4: d = -11
Get all the x terms on one side, and the w on the other.
Add 37x on both sides to get 56x+rx=w.
Use the distributive property backwards to get x(56+r)=w.
Divide by 56+r on both sides to get x=w/(56+r)
There are 4/7 groups of 7/4 in 1 and 3 divided by 7/4 is 12/7
<h3>How to evaluate the expressions</h3>
<u>1. How many groups of 7/4 are in 1</u>
Here, we have:
Groups = 7/4
Entity = 1
The number of groups is calculated as:
Number =Entity/Groups
So, we have
Number = 1/(7/4)
Evaluate
Number = 4/7
Hence, there are 4/7 groups of 7/4 in 1
<u>2. 3 divided by 7/4</u>
Here, we have:
Divisor = 7/4
Dividend = 3
The quotient is calculated as:
Quotient = Dividend/Divisor
So, we have:
Quotient =3/(7/4)
Evaluate
Quotient = 12/7
Hence, 3 divided by 7/4 is 12/7
