Answer:
x = 39
Step-by-step explanation:
The Pythagorean theorem tells you the sum of the squares of the sides of a right triangle is the square of the hypotenuse.
x² +80² = 89²
x² = 89² -80² = 7921 -6400 = 1521
x = √1521
x = 39
Answer:
x=0;y=-2
Step-by-step explanation:
multiply first equation by 6: 18x-24y=48
Subtract 2nd equation from 1st: -19y=38
y=-2
Sub into 1st equation: 3x-4(-2)=8
3x+8=8
3x=0
Therefore, x=0;y=-2
Answer: She paid $66.33
Step-by-step explanation:
The overall amount that you paid for the video game was 87.95. She got 27.79 back as a refund. So you subtract what she paid from her refund. 87.95-27.79 = 60.16. She also had to pay a fine for the video game. So you add the fine to the amount. 60.16+6.17 = 66.33.
Overall, she paid 66.33.
