The - change every sing -m-3n+12
<span>here is some introduction.
A common
language is needed in order to communicate mathematical ideas clearly and
efficiently. Exponential notation is one example. It was
developed to write repeated multiplication more efficiently. For example, growth
occurs in living organisms by the division of cells. One type of cell divides 2
times in an hour. So in 12 hours, the cell will divide 2 • 2 • 2 • 2 • 2 • 2 • 2
• 2 • 2 • 2 • 2 • 2 times. This can be written more efficiently as

Slope: 1.5
y-intercept: -2
Explanation:
The slope is the number attached to 'x' in the equation. In this case, 1.5 would be the slope because it's attached to x.
The y-intercept is the constant the number not attached to any variables. In this case, -2 is all by itself.
Hope that helps!

Answer: choice a
Step-by-step explanation:
Set up your variables. For this question lets use x, y, and z.
the equations will be . .
x + y + z = 165
x = 2y - 65
z = y -10
If we now substitude the equations for x and z with the first equation we cans solve for y. Hence the equation will be . . .
2y - 65 + y + y -10 = 165
y = 60
then substitude the equations for x and z with y.
your answer should match choice a.
Answer: the answer is 54
Step-by-step explanation: The error in the expression was that it was multiplied by 1 so it can't be one unless it was also 1 and it's not it is 54.
