<u>Answer</u>
y = -x
y = (3/2)x - 5
<u>Explanation.</u>
the sum of 2 numbers is 0
That will be,
x + y = 0
Adding x both sides we get,
y = -x
The other statements is,
3x - 2y = 10
Adding 2y on both sides we get,
3x = 10 + 2y
Subtracting 10 both sides we get,
2y = 3x - 10
Dividing both sides by 2 we get,
y = (3/2)x -5
Answer:
her equation should be a² + 3² = 4²
Step-by-step explanation:
a² + 3² = 4²
a² + 9 = 16
a² = 7
a =
a ≈ 2.6 inches
The sum of the interior angles of all triangles is 180 degrees. This means you can set all the angles' expressions equal to 180 and solve algebraically for x.
180 = 3x + 2x + x
180 = 6x
30 = x
Answer:
30°
