1/3minus5/6 is equal to negative 9 over 6 and negative 9/6 divided by 5/6= negative 9/5
Answer: A. The molten mixture of rock-forming substances, gases, and water from the mantle
Magma is a mass of molten rock that is found in the deepest layers of the Earth at high temperature and pressure, and that can flow out through a volcano.
The composition of this mass is a mixture of liquids, volatile and solids that when they reach the surface in an eruption becomes lava, which when cooled crystallizes and gives rise to the formation of igneous rocks.
The total number of rooms in the apartment building is 816
linear pairs are supplementary so their sum equals 180°
(3x - 30) + (x + 76) = 180
4x + 46 = 180
4x = 134
x = 33.5
∠1: 3x - 30 = 3(33.5) - 30 = 70.5
∠2: x + 76 = (33.5) + 76 = 109.5
Answer: ∠1 = 70.5°, ∠2 = 109.5°
