Joe's Painting: 20x + 100 = y
Steve's Painting: 15x + 120 = y
x = hours worked
y = total income
We can find when the two equations intersect by making them equal to each other. That means we put an equal sign in the middle. So, it would look something like this:
20x + 100 = 15x + 120
First, we have to move the 100 by subtracting it from both sides.
20x = 15x + 120 - (100)
20x = 15x + 20
Then, we need to move the 15x by subtracting it from both sides.
20 - (15x) = 20
5x = 20
Lastly, we need to divide 5 from both sides.
5x = 20/5
x = 4
Therefore, Joe and Steve would have to work for 4 hours in order for their models to be equal to each other.
The value of 2/7 expressed as a truncated decimal to the nearest thousandth is 0.286
Rational numbers are numbers written as the ratio of two integers. For example, the fraction 2/7 given is a rational number.
Expressing 2/7 as a decimal number will give;
2/7 = 0.2857142... (It gave repeated decimal values)
Truncating the repeating decimal to the nearest thousandth means writing the decimal to 3 decimal places
0.2857142 = 0.286 (to the nearest thousandth)
Hence the value of 2/7 expressed as a truncated decimal to the nearest thousandth is 0.286

Answer$32
Step-by-step explanation:
125 divided by 2 = 31.25 +00.05+32
Translating this word problem into an algebraic equation, we get:
3x - 2/5 = 8/5.
Let's combine the constants: adding 2/5 to both sides of this equation yields
3x = 10/5, or 3x = 2.
Solving for x: x = 2/3
Answer:
Step-by-step explanation:
The standard form of an equation is when both variables, x & y, are on the same side of the equation with a number on the other side.
To transform this equation from slope-intercept form to standard form, just switch sides for the y and the 9 like follows.
I hope this helped you :D
