X= 9 1/4 or 9.25 in decimal form
Answer:
(-4,2)
Step-by-step explanation:
First we have to find a common multiple to use to add and find the system of equations. We need to eliminate one of the variables in order to solve.
Since 5 * 3 = 15, and 3 * -5 = 15, -15x and 15x will cancel each other out. Therefore x will be eliminated.
Before:
5x + 2y = -16
3x + 7y = 2
After:
15x + 6y = -48 <----------Now we solve for y
-15x + -35y = -10
+----------------------
-29y = -58
-29 -29
y = 2
Now what we do is we choose and equation and solve for x, since it is still unknown. Any equation is fine but I will choose the second one since it has easy numbers.
3x + 7y = 2
3x + 7(2) = 2
3x + 14 = 2
-14 -14
----------------------
3x = -12
3 3
x = -4
Therefore our final answer is (-4,2)
<u>PERIMETER</u>
Answer:
Answer is 28 m
Step-by-step explanation:
Breadth= 2m
Length= 2X6m
= 12m
Perimeter of a rectangle = 2X (Length+ Breadth)
= 2X (2+12)
= 2X14
= 28m
<u>AREA</u>
Answer:
Answer is 24 m
Explanation:
Length= 12
Breadth= 2
Area of a rectangle= Length X Breadth
= 12X2
= 24 sq. m

Answer:
0.43
Step-by-step explanation:
2+3+1+1=7
7*4+28==Area of full shape
(2*4)+(1*4)=12==Area of shaded shapes
12/28=0.428571>rounded up>0.43
