All you do is subtract what John is spending from the amount he has. 20.43-15.39= $5.04
Answer:
False
Step-by-step explanation:
Correlation measures the strength of the relation between two variables.
Further, Correlation is said to be positive if increasing/decreasing the one variable, also increases/decreases the values of another variable.
Correlation is said to be negative if increasing/decreasing the one variable, also decreases/increases the values of another variable.
Since we don't know here exists a positive correlation or negative correlation.
So here are two possible conditions:
The person who has Gum disease also has heart disease.
And, the person has Gum disease can never have heart disease.
Thus, the given statement is false.
First you divide 17.5/ 3 and then the answer multiply by 15 and get 87.5 i think
Given the system of equations below:

The first equation is y-isolated so we can substitute in the second equation.

Use the distribution property to expand in and simplify.

The another method is to divide the second equation by 2.

Arrange in the form of y = mx+b.

When we finally arrange, compare the equation to the first equation. Both equations are the same which mean that both graphs are also same and intersect each others infinitely.
For more information, when the both sides are equal for equation - the answer would be infinitely many. If both sides aren't equal (0 = 4 for example) - the answer would be none. If the equation can be solved for a variable then it'd be one solution.
