Answer:
x=12
Step-by-step explanation:
Both these angles are *supplementary* to each other, this means that (10x-20) and (6x+8) will both equal 180 degrees.
1. Add 10x - 20 and 6x + 8 together
By adding them together, you get 16x - 12
2. Since both of them added together would also equal 180, this means that 16x - 12 = 180
3. Use the additive inverse property and add 12 to both sides. This gives you 16x = 192
4. In order to isolate x, divide 16 on both sides.
192/16 = 12
Therefore, x is 12
Six hundred and seventy six million, five hundred and fourty three thousand seven hundred and eighty nine
(g₀f)(x)=g(f(x))
=g(2x-2)
=5(2x-2)^2-3
=5(4x^2-8x+4)-3
=20x^2-40x+17
Answer: 1430
Step-by-step explanation: x + y + z = 2680
x = 2z - 100
y = 3z + 80
x + y = 5z - 20
6z - 20 = 2680
z = 450
y = 1430
Solution:
x = 800, y = 1430, z = 450
