Answer: 75+50x= 105+35x , required equation.
Step-by-step explanation:
There are three kinds of rock: igneous, sedimentary, and metamorphic.
Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of minerals containing silicon and oxygen, the most abundant elements in the Earth’s crust.
Answer:
120
Step-by-step explanation:
1. Find the value of x.
The angles in a triangle have a sum of 180 degrees. To find x, add up the other two inside angles and subtract the sum from 180.
87 + 33 = 120
180 - 120 = 60 degrees.
x = 60
2. Angle y is supplementary to angle x, meaning that the sum of the two angles equals 180.
180 - 60 = 120
y = 120
Answer:
That's correct
Step-by-step explanation:
In math, we define a quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2. The standard form of a quadratic is y = ax^2 + bx + c, where a, b, and c are numbers and a cannot be 0. Examples of quadratic equations include all of these: y = x^2 + 3x + 1. y = x^2.
