Answer:
When we add polynomials, we ADD the coefficients but keep the VARIABLES the same.
Step-by-step explanation:
"coefficients" are the numbers right next to a variable. "Variables" are the letters we use for unknown numbers in a math phrase(expression) or sentence(equation).
So you only add the number besides the variable when the terms have the same variable.
Example:
4x + 3m + 5x + 2m
= 9x + 5m
See we only added the 4 and the 5 bc they were both beside the x and we added the 3 and the 2 bc they were both beside the m. See image for another example.
There are four numbers of 3-coin combinations if we can choose from nickels, dimes, quarters, and half-dollars.
<h3>How to solve probability combinations?</h3>
The coins to select from are nickels, dimes, quarters, and half-dollars;
Thus;
Coins (n) = 4
The number of coin to select is:
Coin (r) = 3
The coin combination is then calculated using:
Combination = ⁴C₃
Apply the combination formula, we have;
Combination = 4
Thus, there are four number 3-coin combinations if we can choose from nickels, dimes, quarters, and half-dollars.

Based on the table, Josie is paid $43.75 for 5 hours work. For 1 week's work, the pay will be for 40 hours, 8 times that amount, or
.. Josie's weekly pay = 8*43.75 = 350.00
Based on the graph, Salvador gets paid $15.00 for 2 hours work. For 1 week's work, the pay will be for 40 hours, 20 times that amount, or
.. Salvador's weekly pay = 20*15.00 = 300.00
Josie earns 350 -300 = 50 more each week than Salvador. For Josie to earn 1000 more, we can solve the equation
.. 50*weeks = 1000
.. weeks = 1000/50 = 20
It will take Josie 20 weeks to earn $1000 more than Salvador does in the same period.
