1) x + 2xyz
2) 3x + y + z
3) 2x³y + y²x - 3x + 4
4) 9x³yz
Least to greatest: 2 , 1, 4, 3,
Let us assume that x = 3; y = 2; z = 1 and we disregard the coefficients
1) x + 2xyz ⇒ 3 + (3)(2)(1) = 9
2) 3x + y + z ⇒ 3 + 2 + 1 = 6
3) 2x³y + y²x - 3x + 4 ⇒ (3³)(2) + (2²)(3) - 3 = 63
<span>4) 9x³yz </span>⇒ (3³)(2)(1) = 54
Least to greatest ; 2) 6 ; 1) 9 ; 4) 54 ; 3) 63.
We disregarded the coefficients because the expressions are organized based mainly on their degree.
Answer:
y=3.01x
Step-by-step explanation:
We can see that since 19 gallons cost $57.19 and 18 gallons cost $53.18, 1 gallon (19-18) must cost $3.01.
Therefore, y=3.01x
You can check this with algebra

Answer:
1. 6n - 15
2. x + 10
3. -4d + 15
4. true, associative property
5. distributive, commutative
Step-by-step explanation:
1. distribute 3/4 into the parentheses, so multiply 3/4 * 8 and 3/4 * -20
2. distribute the 2 into the parentheses so multiply 2 * 3x and 2 * 5, then combine like terms
3. distribute -3 into the parentheses so -3 * 4D and -3 * -5 then add like terms
4. add like terms on both sides of the equal sign and you get 10x on both sides. this is the associative property because it doesn't matter what's inside or outside the parentheses you get the same answer no matter how you add them up
5. the first part is distributive because you distributed the three into the parentheses and the second part is commutative because you switch them around and you can get the same answer
