Hey there! :)
Answer:
Anna's number = 13.
Olga's number = 52.
Step-by-step explanation:
We can express this situation as an equation to solve for both of their numbers.
Let x be Anna's number
Let 4x be Olga's number
Their numbers sum up to 65, therefore:
4x + x = 65.
Begin by combining like terms:
5x = 65
Divide both sides by 5:
5x/5 = 65/5
x = 13 = Anna's number.
Find Olga's number by plugging 13 into 4x:
4(13) = 52. This is Olga's number.
The answer is: AASProving that two triangles are congruent by AAS can be verified when two angles and a non-included side in the first triangle are equal to their corresponding two angles and non-included side in the second triangle.
For the given parallelogram (check attachment):angle AXB = angle CXD (opposite angle)
angle ABX = angle CDX (alternate angles)
AB = CD (opposite sides in parallelogram are equal)
Therefore,
<span>Triangle AXB is congruent to triangle CXD.</span>
Answer: -4x+2
Step-by-step explanation: Simplify
10.50 x 0.2 = $2.10
Therefore, 20% of $10.50 is $2.10
With 20% off, the book will cost
10.50-2.10 = $8.40
15 square meters. 1.5 times 10 = 15. 15 times 2 equals 30. Divide 30 in half, 15.
