Answer: Kim is 16 and Alan is 20
Kim => x
Alan => y
Kim is 4/5 as old as Alan =>
In four years, she will be 5/6 as old as he will be =>
Solving the system we obtain x=16 and y=20
Step-by-step explanation:
1000 for 50 is store profit
Numbers are -29 and -24.
<u>Step-by-step explanation:</u>
Step 1:
Given the sum of 2 numbers is -53 and their difference is -5. Let the numbers be x and y.
Step 2:
Form equations based on the given data.
⇒ x + y = -53 ------ (1)
⇒ x - y = -5 --------- (2)
Subtract (2) from (1) ⇒ 2x = - 58 ⇒ x = -29
Step 3:
Find the value of y.
⇒ y = -53 -x = -53 + 29 = -24
The approximate solution you require is the x coordinate of the point of intersection of the 2 graphs.
Please find the attached file for a proper understanding of the question given here. The diagram in the file attached is the complete accompanying diagram of the question.
As per that diagram, (which is given)
and we know that (vertically opposite angles).
Thus, the only way ΔDSB ≅ ΔTSR by SAS is when as indicated in the diagram.
Thus, is the correct answer.
