It's already in scientific notation form;
Answer of your question,
3x+46 = 10x-80
7x = 34
x = 4.85
Answer: 4. (-1,-1) 3. (3,-2)
4)
Set the equations equal to each other.
4x+3=-x-2
Subtract 3 from both sides
4x=-x-5
Add x to both sides
5x=-5
Divide both sides by 5
x=-1
Next, replace x with -1 in either equation to find y.
-(-1)-2=y
-1=y
3)
Do the same thing for this one and set them equal to each other
-2x+4=-1/3x-1
Add 1 to both sides
-2x+5=-1/3x
Add 2x to both sides
5=5/3x
Divide both sides by 5/3
x=3
Next, replace x with 3 in either equation
-2(3)+4=y
-2=y
To get from 40% to 100%, divide by 2 and multiply by 5.
I.e. 40/2 = 20
20 x 5 = 100%
Do the exact same for 102
102/2 = 51
51 x 5 = 255 students
If x, then not y, if not y, then z. Y is true. So: X is true, Z is True
<h3>How to Interpret Conditional Statements?</h3>
A conditional statement is a type of structure to express the relationship between two dependent variables. Its structure is as follows:
If P, then Q...
Now, from the question we are told that;
If x, then not y, if not y, then z.
Y is true. So:
Now, when looking at conditional statements in depth, and comparing to this question we can easily see that since Y is true, then it means that if X is true, then Z is also true.
Thus,
If x, then not y, if not y, then z.
Y is true. So: X is true, Z is True
