Answer:
The equation for charge is = current x times
Answer:
X=3
Y=1
Step-by-step explanation:
In solving simultaneous equations, there are three methods, we have the elimination method, substitution method or graphical method. But for the purpose of this question, we would be using Elimination method.
5y-4x =-7 Equation 1
2y+4x=14 Equation 2
Since x has the same coefficient, it's easy to eliminate by adding up the two equations
5y+2y=7y
-4x+(+4x)=0
-7+(+14)=7
We have 7y=7
Divide both sides by 7,
y=7/7
y=1
Substituting for y in equation 2.
2(1)+4x=14
2+4x=14
4x=14-2
4x=12
x=12/4
x= 3
Answer:
$291.00
hope it helps
Step-by-step explanation:
12 x 8.75 = 105
6 x 12.50 = 75
12 x 9.25 = 111
105 + 75 + 11 = 291
This is not a quiestion but the area of this shape is 401.92inches. A=2πrh+2πr2
