Create a ratio and cross multiply
20x - 75 = 14x + 63
6x = 138
x=23
hope this helps :)
is interest per 1 year? if so:
interest per year=9%×1000
=90
interest for .5 years=90÷2
=45
1000+90+45=1135
Ans: 1135
E. II or IV only because it will have different signs if point Q was in either of those quadrants
To write the polynomial in descending order, arrange the terms from the highest to the lowest degree. Simply base on the exponents of the variable x. You have 3, 12, 1 and 7. In descending order, that would be: 12, 7, 3 and then 1. The answer is D.
The partial would be
40x5=200
2x5=10
210
Your just breaking them apart
