1st multiply the top equation by -1 to get -3x - y = -17 then add the 2 equations together to get:
4x + y - 3x - y = 18 - 17
x = 1 (simplified down)
Now plug the 1 into either equation
4(1) + y = 18
4 + y = 18
y = 18 - 4 = 14
Your point is (1, 14)
The area of a parallelogram is the product of the length of the base and the height measured perpendicular to the base.
1i) (20 cm)*(12 cm) = 240 cm^2
2ii) (7 cm)*(7.5 cm) = 52.5 cm^2
3iii) 27 cm^2 = (6 cm)*h
.. h = (27 cm^2)/(6 cm) = 4.5 cm
Answer:
25.8
Step-by-step explanation:
divide
Answer:
R = V/I
Step-by-step explanation:
I = V/R
Multiply both sides by r
IR = V
Divide both sides by I
R = V/I
Ex:
2 = 6/3
3 = 6/2
