How do you combine like terms to simplify algebraic expressions?
Answer: To combine like terms, we must first understand what they are. Like terms are, well like. An example will make more sense. See the equation 2 + 4x - 5y * 0.2xy. Here, we have no like terms. Why? Because 2 has no variable while 4x has x. However, 4x and 5y don't have the same variable so they are NOT like either. Do not fall into the 0.2xy trap either because that is not like with 4x or 5y. Now that you (hopefully) understand let us try an example.
5x * 2x - 24 = 16
As you can see, the like terms here are 5x and 2x as well as 4 and 16. Now let us simplify by bringing the like terms together.
5x * 2x = 16 + 24
10x^2 = 40 (Be careful here! since we are multiplying x twice it will become x^2)
x^2 = 40/10
x^2 = 4
x = 2 (or -2)
And there you go! You just simplified using like terms.

A car is traveling at a steady speed. It travels 2 1/2 miles in 3 1/3 minutes. How far will in 49 minutes? In 1 hour ?
2 1/2 miles / 3 1/3 minutes = 3/4 mile per minute
A. 3/4 mile per minute x 49 minutes = 35 3/4 miles
B 3/4 miles per minute x 60 minutes (1 hour) = 45 miles
Answer:
2 1/2 miles = 5/2 miles
3 1/3 minutes = 10/3 minutes
Here,
in 10/3 minutes travels = 5/2 miles
in 1 minutes travels = (5/2)/(10/3) miles
in 49 minutes travels = (49*(5/2))/(10/3) miles = 36.75 miles
in 60 minutes (1 hour) travels = (60*(5/2))/(10/3) miles = 45 miles

Arsenic-74 is used to locate brain tumors. It has a half-life of 17.5 days. 90 mg were
used in a procedure. Write an equation that can be used to determine how much of
the isotope is left after x number of half-lives.
The exponential function that can be used to determine how much of the isotope is left after x number of half-lives is given by:
[tex]A(x) = 90(0.5)^x[/tex]
What is an exponential function?A decaying exponential function is modeled by:

In which:
A(0) is the initial value.r is the decay rate, as a decimal.In this problem, the initial amount is of A(0) = 90 mg, and we are working with half-lifes, hence r = 0.5, which means that the equation is:

Each statement describes a transformation of the graph of f(x) = x. Which statement correctly describes the graph of g(x) if g(x) = f(x-11)?
Step-by-step explanation:
f(x) = x
g(x) = f(x - 11)
g(x) = x
g(x) = (x - 11)
g(x) = x - 11
So, g(x) = x - 11

You use 4 gallons of water on 30 plants in your garden. At that rate, how much water
will it take to water 45 plants?
gallons
6 gallons
If you have 4 gallons for 30 plants, half of 4 gallons is 2, which will water 15 plants. Add 4 gallons plus 2 gallons, it gives you 6 gallons and 45 plants.
It use 6 gallons of water to water 45 plants.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
WE have been given that;
Let 4 gallons of water ... 30 plants
Let x gallons of water = ? ... 45 plants
The water will it take to water 45 plants, it can be calculate this using the following steps;
4 * 45 = x * 30
180 = 30 * x /30
x = 180 / 30
x = 6 gallons of water
Therefore, We will use 6 gallons of water to water 45 plants.

Answer:
For the function f(x) = 3x - 8,
f(0) = -8
f(4) = 4
f(-4) = -20
f(1/3) = 7
Step-by-step explanation:
Given:
f(x) = 3x - 8
f(0) = 3(0) - 8
f(0) = 0 - 8
f(0) = -8
f(4) = 3(4) - 8
f(4) = 12 - 8
f(4) = 4
f(-4) = 3(-4) - 8
f(-4) = -12 - 8
f(-4) = -20
f(1/3) = 3(1/3) - 8
f(1/3) = 1 - 8
f(1/3) = 7

The mass of a lorry and its load is 2.87t. What is the mass of the load in kg, if the mass of the lorry is 1.225 tonnes?
a) 1.645kg
b) 1645kg
c) 1225kg
d) 0.001645kg
The mass of the load in kilogram is an illustration of subtraction operation
The mass of the load in kilogram is (b) 1645 kg
The complete mass is given as:
[tex]\mathbf{m_t = 2.87\ tonnes}[/tex]
The mass of the lorry is given as:
[tex]\mathbf{m_l = 1.225\ tonnes}[/tex]
The mass of the load is calculated by subtracting the mass of the lorry from the mass of the lorry and its load.
So, we have the following equation:
[tex]\mathbf{m_{load} = m_t - m_l}[/tex]
Substitute known values
[tex]\mathbf{m_{load} = 2.87\ tonnes- 1.225\ tonnes}[/tex]
Subtract
[tex]\mathbf{m_{load} = 1.645\ tonnes}[/tex]
Convert to kilogram
[tex]\mathbf{m_{load} = 1.645 \times 1000kg}[/tex]
Multiply
[tex]\mathbf{m_{load} = 1645 kg}[/tex]
Hence, the mass of the load in kilogram is (b) 1645 kg
