Answer:
i cannot help you get the answer to the question without more information but i can explain how to solve it, what your question is, is called a "permutation"
Step-by-step explanation:
To calculate permutations, use the equation nPr, where n is the total number of choices and r is the amount of items being selected. To solve this equation, use the equation nPr = n! / (n - r)! , an exclimation point means the factorial, say we need the factorial of 4, we would do this 4x3x2x1 go left to right, and it is not all at once. you multiply 4 times 3 which equals 12, then multiply 12 times 2... so on and so forth
Hey there!
Let us take Michael's score as ' x '
Let us take Kathryn's score as ' y '
Michael - 70 less than twice Kathryn's
x = 2y - 70
y = y
Add them, we get , 425
2y - 70 + y = 425
3y - 70 = 425
3y = 495
y = 495/3
y = 165
Kathryn's score = 165
Michael - 2 ( 165 ) - 70
= 260
Hope it helps!
