Answer: D
Step-by-step explanation:
Let's take one of the equations and solve for a variable to use the substitution method.
Now replace this in the first equation.
Separate the terms.
Solve 20/5
Subtract 4 from both sides to isolate y.
Solve the difference.
Multiply by the reciprocal or the inverted fraction that is next to y to isolate it.
Now, in order to find x, replace y in any of the two equations.
False, an isosceles triangle has 2 equal sides.
Step-by-step explanation:
Perimeter= 62 cm
4 × side = 62
side = 62/4
=15.5 cm
Area = (side)²
= (15.5)²
=240.25 cm²
The paint required to cover 1 door is 5/4 liters.
Step-by-step explanation:
The paint required to cover 1 3/5 doors = 2 liters.
Convert mixed fraction into proper fraction.
Therefore, the paint required to cover 8/5 doors = 2 liters.
The paint required to cover 1 door = x liters.
To find x :
Comparing the given data and the unknown data.
8/5 door / 2 liters = 1 door / x liter
x = 2 × 5/8
x = 10/8
x = 5/4 liters.
The paint required to cover 1 door is 5/4 liters.
