Answer:
10
Step-by-step explanation:
32 - 12 (because C is 12 years younger) = 20
20 / 2 (because <em>twice</em> Anna's age, so we do the inverse) = 10
Anna is 10 years old.
Hope this helps!
Answer:
exactly one
Step-by-step explanation:
The system of linear equations have:
one solution, infinitely many solutions or no solution.
One solution if the lines intersect.
Infinitely many solutions if the lines are the same (overlap)
There is no solution if the lines are parallel (they do not have a common point).
In the graph, two lines intersect. Therefore, the system of equations has one solution (0, 3).
Answer:
1.2
Step-by-step explanation:
The x in each point is 3 so we can leave that alone.
Then we subtract.
2.6 - 1.4 = 1.2
Area of the figure = 112 in²
Solution:
The given figure is splitted into two shapes.
One shape is square.
Each side of square are equal.
Side = 10 inch
Area of the square = side × side
= 10 × 10
= 100
Area of the square = 100 in²
The other shape is triangle.
Base of the triangle = 10 in – 6 in = 4 inch
Height of the triangle = 16 in – 10 in = 6 inch
Area of the triangle = 

= 12
Area of the triangle = 12 in²
Area of the figure = Area of the square + Area of the triangle
= 100 in² + 12 in²
Area of the figure = 112 in²
Therefore, area of the given figure is 112 in².
Answer: x= 8
Step-by-step explanation:
According to the converse of basic proportionality theorem,
If in ΔABC , DE is a line drawn from AB to AC such that 
then, DE is parallel to the third side BC.
Applying converse of basic proportionality theorem, to get NO parallel to KJ, we must have

Hence, the value of x should be 8, so that Line segment N O is parallel to line segment K J.
