Answer:
DF=20 bc find the number it is being multiplied by and it's 4. 5 × 4 is 20.
Answer:
A. 9 × (11 – 4) is three times as much as 3 × (11 – 4)
Step-by-step explanation:
9 is 3×3, so we can write the expression involving 9 as ...
... 9 × (11 - 4) = 3 × 3 × (11 - 4)
... = 3 × (3 × (11 -4))
This clearly shows that 9 x ( ) is 3 times as much as 3 × ( ).
Each person gets 2 2/3 cups of ice-cream
Step-by-step explanation:
First, you convert 6 quarts to cups. For every quart, there are 4 cups so you do 6 times 4 and you get 24 then you divide 24 by 9 and you get 2 2/3
First do distributive property
2x + 10 + 3x = 30
Now combine like terms
5x + 10 = 30
Subtract 10 from both sides
5x = 20
Divide both sides by 5
x = 4
Answer: 2 cups
Step-by-step explanation: Olivia spends 4$ and nothing more. 1$ is her profit that can continue to gain and can be represented as 1x or x. x-4 is the equation to represent her profit. Nathan spends 5$ and 0.50$ is his profit which can be shown as 0.5x. 0.5x-5 is the equation to represent his profit.
Set those two equations equal to each other.
Isolate x.
Solve for x.
Since x represents the amount of cups sold, you cannot have a negative amount of cups sold. Therefore, Olivia and Nathan must sell 2 cups to make the same profit.
