If both binomials have the same variables to the same powers, then it is true. In general, multiplying binomials gives four terms, one corresponding to each letter of the FOIL acronym. So, you only get a trinomial when the O and I terms combine.
For this case we must resolve the following inequality:
Subtracting 8 from both sides of the inequality:
Equal signs are added and the same sign is placed.
Thus, the solution is given by all values of "y" greater than or equal to -20.
Answer:
"y" belongs to the set [-20,∞)
Start by multiplying 15 by 5, and you get 75. then subtract that from 82, and you get 7. Since you are below the surface, the number is negative. So you get -7.
Answer:
Divide 15 by 12. The remainder, 3, will be 3/12, or 1/4. Add 1 and 1/4, and you'll get 1 1/4.
Step-by-step explanation:
Well lets see...If we did the math about the total ammount of bills we will make a formula starting off as 5(124-x)-10x=840 and using the 5 dollar bills equal to x
distribute the 5 first for 620-5X-10X=840 840 minus 620 gives us 220 and divide 220 by 5 which will give us 44 5 dollar bills, now we do the 10 dollar bills. let Y=10 for the next equation of 5Y+10Y=840, substitute the 10Y with your answer for 5 resulting in 5Y+10(44)=840 10 times 44 is 440 and now subtract 440 from 840 resulting in 5Y=400 divide the 400 by 5 and get a new answer of Y equals 80 for ten dollar bills
X=44
Y=80
44+80=124
