Answer:
C. 
Step-by-step explanation:
Given the two equations:
To find:
The correct option when value of y is substituted to 2nd equation using the 1st equation.
Solution:
First of all, let us learn about the substitution method.
Substitution method is the method to provide solutions to two variables when we have two equations and two variables.
In substitution method, we find the value of one variable in terms of the other variable and put this value in the other equation.
Now, the other equation becomes only single variable and then we solve for the variable's value.
Here, we have two equations and value of one varible is:
Let us put value of y in 2nd equation:
So, the correct answer is option C.
Let Us Call <span>better</span>
translate 5 hours and 15 min into all min to find the total for us cell u. 5*60=300, so 315 minutes. So then multiply .15 by 315 and you get 47.25$.
<span>Now do Call for us. so first multiply 5 by 10.50. you get 52.50$.</span>

Answer:
Given that,
In right triangle ABC, C is the right angle.
sin A=0.4
To find cos B,
we get the triangle as,
we know that,
Hypotenuse of the triangle is AB
For the angle A, opposite side is CB
For the angle B, adjacent side is CB
From the definition of sine and cosine we get,
Also,
Comparing both we get,
It is given that sinA=0.4
Hence we get, cosB=0.4
Answer is: 0.4
The answer is 90x2y3 since 18 and 15 have an LCM of 90, and x2y3 and xy2 have an LCM of x2y3.
