Answer:
x = 11, y = 9
Step-by-step explanation:
Given the 2 equations
x + y = 20 → (1)
3x - 3 = 30 → (2)
In (2) add 3 to both sides
3x = 33 ( divide both sides by 3 )
x = 11
Substitute x = 11 into (1)
11 + y = 20 ( subtract 11 from both sides )
y = 9
Using the old equation, a squared + b squared = c squared. C would be your hypotenuse
so yes it is a correct right triangle
This means that you have to move the decimal point 4 decimal places to the left, as denoted by the negative sign. Thus, this would add 3 zeros before 5. The answer would be 0.00059.
I hope the explanation was clear to you. Have a good day.
I believe the answer is
7(1)-1 =6
7(2)-1 =13
7(3)-1 =20
7(4)-1 =27
7(5)-1 =34
