Answer:
25
Step-by-step explanation:
5(n-8)=3n+10
5n-40=3n+10
5n=3n+50
2n=50
n=25
Eric has 46 total marbles (4*10)+6
Answer:
B. Carl yearns more per hour
C. put line through points (1,15) and 3,45) on graph and you will have Carl's earnings per hr.
Step-by-step explanation:
Louis earns 12$ per hr (y=12x)
Carl yearns 15$ per hr (y=15x)
to find what carl yearns hourly you divide 45 by 3 which is 15.
(Explaination of answer for question b)
C isnt hard once you find y=15x.
A Pythagorean triple is a set of thre integer numbers, a, b and c that meet the Pythgorean theorem a^2 + b^2 = c^2
Use Euclide's formula for generating Pythagorean triples.
This formula states that given two arbitrary different integers, x and y, both greater than zero, then the following numbers a, b, c form a Pythagorean triple:
a = x^2 - y^2
b = 2xy
c = x^2 + y^2.
From a = x^2 - y^2, you need that x > y, then you can discard options A and D.
Now you have to probe the other options.
Start with option B, x = 4, y = 3
a = x^2 - y^2 = 4^2 - 3^2 = 16 -9 = 7
b = 2xy = 2(4)(3) = 24
c = x^2 9 y^2 = 4^2 + 3^2 = 16 + 9 = 25
Then we could generate the Pythagorean triple (7, 24, 25) with x = 4 and y =3.
If you want, you can check that a^2 + b^2 = c^2; i.e. 7^2 + 24^2 = 25^2
The answer is the option B. x = 4, y = 3
