Elga's age = x
Alvin's age = x + 7
x + x + 7 = 97.
Simplify the left side of the equation
2x + 7 = 97.
Subtract 7 from each side
2x = 90.
Divide each side by 2
x = 45
Since x is equal to Elga's age, Elga is 45 years old
Answer: The similar figures are 1,4,6. The figure 2 and 5 have different shape. The figure 3 have different ratio of side lengths.
Explanation:
The given figure is a rectangle with length 6 yd and width 2 yd.
The figure 2 shows a triangle and figure 5 shows a parallelogram, therefore the figure 2 and 5 have different shape.
Two figure are called same if their corresponding sides have same proportion.
The figure 1 and 4 have two sides having length 2 yd and 6 yd, So, the figure 1 and 4 shows the similar figure.
The figure 6 have sides 4 and 12 which is twice of side length of given figure, therefore the sides increased by same proportion 2.
Thus, the figure 1,4,6 shows the figure similar to given figure.
In figure 3 the length is 6 and width is 3. The length is same but the width is different.
Therefore the figure 3 have different ratio of side lengths.
Answer:
13n+20
Step-by-step explanation:
If 20 is the flat rate, then you dont put x to it. X is how many books you are going to get and 13 is how much you have to pay for each book. If that makes sense.

Answer:
Step-by-step explanation:
In any triangle, the Law of Sines states that the proportion of the sine of each angle and its opposite side is maintained throughout all 3 angles and their corresponding sides of a triangle:
Thus, we have
