Answer:
Yes
Step-by-step explanation:
The intersection point of 10x+4y=18 and x+9y=19 is (1,2) on a graph.
Answer is 13.75 inches for each side of the square board
Step by step
A square with an area of 189 in sq. , take square root of 189 = 13.75 inches
$13 is your answer. Multiply 3x5 then subtract the total from 28
Area of a rectangle = length times width.
Here, the area is (5 yd)(4 yd) = 20 yd^2. We must convert this into ft^2:
20 yd^2 3 ft
------------ * { ----------- }^2
1 1 yd
The comes out to (20)(3)^9, or 180 ft^3, the area in square feet.
It is 1:2 since it is 7:14 then simplified. Hope this helps...
