The answer is
Let's build the expression piece by piece, translating sentences into formulas:
"3/5 times..."
"5 less than a number..."
So, the first block becomes
"3/5 times 5 less than a number..."
"...is no more than 27"
So, putting the pieces together, you have the answer
Answer:
1. 6/15, 0.4, 40%
2. 0.15, 15%
3. 18 green marbles
Step-by-step explanation:
Answer:
Here Ariel is wrong because 3x^3 is higher power than y^2
3x^3 goes first
then the mixed term -4x^2y
then the y^2
then the 2
So, Marcus is right
Standard form means that you write the terms by descending degree. here's main rules how to write polynomial expression in the standard form:
1. write the term with the highest exponent first (terms of third degree in our case 3x^3 );
2. write the terms with lower exponents in descending order (term -4x^2y followed by y^2
);
3. remember that a variable with no exponent has an understood exponent of 1 (here are no such terms);
4. a constant term (a number with no variable) always goes last (term 2).
10(x2) = 70(x)
10x2 - 70x
10x = 70
