Answer:
Im 25% Italian And 50% dutch
Step-by-step explanation:
A^2 + b^2 = c^2....a and b are the legs and c is the hypotenuse
6^2 + b^2 = 12^2
36 + b^2 = 144
b^2 = 144 - 36
b^2 = 108
b = sqrt 108
b = 10.39 cm <== length of the other leg
=============================
q + d = 17....d = 17 - q
0.25q + 0.10d = 3.05
0.25q + 0.10(17 - q) = 3.05
0.25q + 1.7 - 0.10q = 3.05
0.25q - 0.10q = 3.05 - 1.7
0.15q = 1.35
q = 1.35/0.15
q = 9 <=== there is 9 quarters
B divided by 10 looks like this . . .
b/10
b divided into 10 looks like this . . .
10/b
The difference is that they are inverse of each other.

hopefully i’m right
Answer:
(10, 3)
Step-by-step explanation:
Solve by Substitution
2x − 4y = 8 and 7x − 3y = 61
Solve for x in the first equation.
x = 4 + 2y 7x − 3y = 61
Replace all occurrences of x with 4 + 2y in each e quation.
Replace all occurrences of x in 7x − 3y = 61 with 4 + 2y. 7 (4 + 2y) − 3y = 61
x = 4 + 2y
Simplify 7 (4 + 2y) − 3y.
28 + 11y = 61
x = 4 + 2y
Solve for y in the first equation.
Move all terms not containing y to the right side of the equation.
11y = 33
x = 4 + 2y
Divide each term by 11 and simplify.
y = 3
x = 4 + 2y
Replace all occurrences of y with 3 in each equation.
Replace all occurrences of y in x = 4 + 2y with 3. x = 4 + 2 (3)
y = 3
Simplify 4 + 2 (3).
x = 10
y = 3
The solution to the system is the complete set of ordered pairs that are valid solutions.
(10, 3)
The result can be shown in multiple forms.
Point Form:
(10, 3)
Equation Form:
x = 10, y = 3
