Answer:
4th degree binomial
Step-by-step explanation:
x^3y + 5xyz
Add the exponents on each term
3+1 = 4 1+1+1 =3
The highest power is the degree, so it is a 4th degree
It also has 2 terms so it is a binomial
4th degree binomial

1/5 is the answer. How to slove: You turn the mixed number into an improper fraction which would be 15/4 =, because 4(3)= 12 + 3 = 15 and the denominator stays the same so it would be 15/4. Next, multiply ( the but dont forget to "flip" the improper fraction so it's 4/15) 3/4(4/15)= 1/5
Answer:
x = -87
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction

First, subtract 265 from both sides of the equation:
3x + 265 (-265) = 4 (-265)
3x = 4 - 265
3x = -261
Next, divide 3 from both sides:
(3x)/3 = (-261)/3
x = -261/3
x = -87
x = -87 is your answer.

All you have to do for this problem is take 3, over the 20, and then turn into a percent. Your final answer is D. 15%, because if you multiply 3/20 by 5, you get 15/100, which is easier to turn into a percent, leaving you with 15%
