An example of Algebra 1 Houghton Mifflin Harcourt is quantitative reasoning such as Rewrite the term 9a+4b+(-18).
<h3>What is a algebra in math?</h3>
Algebra is known to be a part of mathematics that handles problems with symbols or variables and it is known to often uses arithmetic operations such as (+, –, ×, ÷) to look for an unknown quantities.
To rewrite the terms, known that the terms are part of the expression that are said to being added. Therefore, for one to be able to rewrite subtraction as addition in the expression,
9a+4b+(-18)
Then it will be
9a, 4b, - 18

Answer:
69.0
Explanation:
69.0 g of pcI5 will be produced from the given masses of both reactants.
Yes they did. You could even get the death penalty if you killed a cat.
They treated them so well because they protected their grains and other foods from rodents
Cats also helped protect their ancient libraries.
The theory of plate tectonics cannot be used in explaining: the origin of the Earth's core.
<h3>What is a tectonic plate?</h3>
A tectonic plate is also known as lithospheric plate and it can be defined as an enormous, solid, irregularly shaped rock slab, that comprises two (2) plates:
- Continental plates
- Oceanic plates
<h3>The theory of plate tectonics.</h3>
The theory of plate tectonics states that the solid outer crust of planet Earth (lithosphere) is typically divided into enormous (massive) slabs of solid rock (plates) that move over the asthenosphere, including the upper portion of the mantle.
<h3>The uses of the theory of plate tectonics.</h3>
- It can be used to explain the presence of magnetic anomalies on the ocean floor.
- It can be used to explain the geographical distribution of earthquakes and volcanoes.
- It can be used to explain the presence of glacial deposits in tropical areas.
- It can be used to explain the origin of mountains.

The volume occupied by this oxygen gas is equal to 10.0 Liters.
<u>Given the following data:</u>
- Mass of oxygen gas = 4.8 grams
- Temperature = 133°C to Kelvin =
- Molar mass of oxygen gas =
= 31.998 g/mol.
<u>Scientific data:</u>
- Ideal gas constant, R = 0.0821 L⋅atm/mol⋅K
To determine the volume occupied by this oxygen gas:
First of all, we would calculate the number of moles of oxygen gas;
Number of moles = 0.15 moles.
Now, we can determine the volume by using the ideal gas law equation;
<u>Where;</u>
- n is the number of moles of a gas.
- R is the ideal gas constant.
Substituting the given parameters into the formula, we have;
Volume, V = 9.9998 ≈ 10.0 Liters.
