Answer:3.86
Step-by-step explanation:
The longest side in the triangle is opposite to the largest angle of this triangle. If triangle is acute, then all angles are acute. Acute angle has cosine that is positive.
Use cosine theorem to determine the cosine of the largest angle:
where 
is the largest angle.
Then
Since 
then
Divide this inequality by 5:
Note that 
then the smallest possible whole-number value of x is 7.
Answer: correct choice is B

Answer:
x=8/5
Step-by-step explanation:
2/3(18x-12)=7-3(x-3)
2/3(18x-12)=7-3x+9
12x-8=-3x+16
12x-(-3x)-8=16
12x+3x-8=16
15x-8=16
15x=16+8
15x=24
x=24/15
simplify
x=8/5
The inequality that describes the calories burned is 7x + 9y ≥ 441
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
let x represent the number of minutes of running and y represent the number of minutes of swimming, hence:
7x + 9y ≥ 441
The inequality that describes the calories burned is 7x + 9y ≥ 441
