I can only answer b. Baseboard is perimeter and carpet is area.
Answer:
The solution is x = -2 and y = 2.
Step-by-step explanation:
Given that:
14y - 8x = 44 Eqn 1
-7y = -x - 16 Eqn 2
In elimination method, you try to eliminate one variable in the equation by adding or subtracting.
Multiplying Eqn 2 by 2
2(-7y = -x - 16)
-14y=-2x-32
-14y+2x= -32 Eqn 3
Adding Eqn 1 and 3
(14y-8x)+(-14y+2x)=44+(-32)
14y-8x-14y+2x=44-32
-6x=12
Dividing both sides by -6
Putting x=-2 in Eqn 2
-7y=-(-2)-16
-7y=2-16
-7y=-14
Dividing both sides by -7
Hence,
The solution is x = -2 and y = 2.
Answer:
Part A: 6 Part B: Put a line from the top right corner to the bottom left corner. Each triangle's area would be 3.
Step-by-step explanation:
PART A
The formula to find the area for a parallelogram is A = bh (Area = base · height)
A = bh
A = 8 · 3/4
A = 6
PART B
Draw a parallelogram if you need to show work and then just connect the top right corner and the bottom left, or top left to bottom right. If 6 (area of the parallelogram) ÷ 2 (since there is two triangles) = 3, then the area of the triangles has to be 3.
1/3 divide by 1/4
flip the 2nd number and the sign from division to multiplication
1/3 x 4/1
multiply
4/3
