The model suggests the equation 3x-4 = 6-2x and the solution is x = 2.
What is equation?
In arithmetic, associate equation could be a formula that expresses the equality of 2 expressions, by connecting them with the sign =
Main body:
According to question,
there are 3 bars for x and 2 bars for -x so it shows
The equation becomes :
3x - 4 = 6-2x
5x = 10
x =2
Hence the solution to this equation is 2.

For this case we have to represent the following expression algebraically:
"10 less than x is -45"
So:
10 less than x is represented as: 
Then, the complete expression is represented as:
Adding 10 to both sides of the equation:
Thus, the value of the variable is 
Answer:
Answer:
24 miles per hour
Step-by-step explanation:
A cyclist travels 6 miles in 15 minutes. What is her average speed in mph?
Step one:
given data
distance= 6 miles
time= 15 minutes
convert minutes to hours
15 minutes is 0.25hours
Step two:
speed= distance/time
speed= 6/0.25
speed= 24 miles per hour
Answer:
The last one.
Step-by-step explanation:
The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope. (Atomic mass is also referred to as atomic weight, but the term "mass" is more accurate.)
