Answer:
x = 12z + 1 and y = 10z - 1
Step-by-step explanation:
To solve the system of equations, we can use the substitution method
If we call
3x - 4y + 4z = 7 I
x - y - 2z = 2 II
2x - 3y + 6z = 5 III
Clearing II x = 2 + y + 2z
Now, replacing II in III
2(2 + y + 2z) - 3y +6z = 5
4 + 2y + 4z - 3y + 6z = 5
10z - y = 1 from here y = 10z - 1
Finally, replacing y in I
3x - 4(10z - 1) + 4z = 7
3x -40z + 4 + 4z = 7
3x - 36z = 3
3x = 36z + 3
x = 12z + 1
Done
Answer:
A) 1:1
Step-by-step explanation:
Each leg is the same value and the hypotenuse is 
of the value.
Area of rectange = 5 x 8 = 40
area of green triangle = 1/2(8)(1) = 4
area of yellow triangle = 1/2(4)(8) = 16
area of blue triangle = 40 - (4+16) = 40 - 20 = 20
answer
C. 20
