Answer:
D
Step-by-step explanation:
2y=10x
Divide both sides by 2.
y=5x
Now substitute this into the second equation.
The equation that best describes the distance traveled is y = 190 + 65x.
Finding the values of the variables that lead to the stated equality being true is a step in the process of solving an equation with variables. Equation solutions are the amounts of the unknowns that meet the equality, whereas unknowns are the variables with which the equation must be solved.
Identity equations and conditional equations are the two types of equations. For every possible value of a variable, an identity holds true. The variables in a conditional equation can only have certain values.
An equation is made up of two expressions connected together by an equals symbol ("=").
The Distance traveled by car is 190 miles
The Speed of the car is 65 miles per hour.
Let x be the total number of hours traveling by car and y be the total distance remaining.
Then,
Total distance = 190 miles + 65 miles per hour × Number of hours traveled.
y = 190 + 65x
Consequently, the equation is y = 190 + 65 x.

I think it’s 6
Sorry if I’m wrong
Answer:
Step-by-step explanation:
we know that
The formula of law of cosines is equal to
where
a, b and c are sides. C is the angle opposite side c
In this problem we have
substitute the given values
so 1.25 is the right answer not sure tho
