Subtraction property of equality is used when u have 2 sides with an equal sign in the middle and u want to subtract from both sides.
Example :
2x + 3 = 7 ....subtract 3 from both sides
2x + 3 - 3 = 7 - 3
2x = 4
x = 4/2
x = 2
When subtracting real numbers..if the numbers are on the same side of the equal sign...u can just subtract on that one side
Example :
2x = 7 - 3
2x = 4
x = 4/2
x = 2
I’m pretty sure it’s 86, because you need to subtract 2 from the first side then you have 86 = X
We're comparing 80,000 with 80.
One way to do this is divide the two numbers: 80,000/80 = 1000.
80,000 is one thousand times greater than 80.
Answer:
Step-by-step explanation:
Since we are in quadrant 2, sine is positive. Since sine is positive and cosine is negative, then tangent is negative.
Now I'm going to find the sine value of this angle given using one of the Pythagorean Identities, namely 
.
If given 
, then we have 
by substitution of .
Let's solve:
for 
.
Subtract 4/9 on both sides:
Simplify:
Square root both sides:
===========
Multiplying top and bottom by 3 gives:
I'm going to move the factor of -1 to the top:
Answer: 3 square root of 2
