X=5.4 because that is how i figured out the answer and I didn’t even figure out
hello ....
the equation of a plane that is ; ax+by+cz +d =0
the vector perpendicular to this plane is : V(a,b,c)
in this exercice ; a = -4 b= -4 c = -1
then: the equation of a plane that is ; -4x-4y-z +d =0
but the plane passing through the point (−2,−5,5) :
-4(-2)-4(-5)-(5) +d =0
23+d =0
d =-23
the equation of a plane is : -4x-4y-z-23 =0
B=90
I think this is the answer
If Lianne has some dimes and nickels with a total value of $4.60. The number of dimes she has is 4 more than 3 times the number of nickels then 0.15 Nickels does Lianne has.
<h3>What is Equation?</h3>
Two or more expressions with an Equal sign is called as Equation.
Given,
Lianne has some dimes and nickels with a total value of $4.60.
The number of dimes she has is 4 more than 3 times the number of nickels.
We need to find number of nickels
From the given information
N+D=4.60
D=3N+4
N+3N+4=4.60
4N=4.60-4
4N=0.6
Divide both sides by 4
N=0.15
Hence, 0.15 Nickels does Lianne has.
