Zhao Xue wants to buy milk and yogurt. She wants to buy a total of at least 6.5 gallons of dairy products (condition A), and she has a budget of $20 (condition B). The graph represents the constraints on the number of gallons of milk M and yogurt Y Zhao Xue buys. Zhao Xue buys 4 gallons of milk. how many gallons of yogurt can she buy to meet both her constraints? A.) Exactly 2.5 gallons
B.) At least 4 gallons and at most 6.5 gallons
C.) At least 2.5 gallons and at most 4 gallons
D.) Zhao Xue doesn’t have enough money left to buy any yofurt

Answer: The answer is (D). Zhao Xue doesn’t have enough money left to buy any yofurt
Step-by-step explanation: Given that Zhao Xue is buying buy milk and yogurt, a total of at least 6.5 gallons of dairy products and she has a budget of $20. The given graph represents the constraints on the number of gallons of milk 'M' and yogurt 'Y' Zhao Xue buys. Zhao Xue buys 4 gallons of milk. We need to calculate the number of gallons of yogurt she can buy to meet both her constraints.
From the graph, we can write
Condition A :
Condition B :
Now, if she buys 4 gallons of milk, the the conditions become
Here, there will be no solution to these constraints.
Therefore, she does not have enough money left to buy any yogurt.
Thus, the correct option is (D).
Answer: exactly 2.5 gallons

I'm guessing you mean to say that sum of 5 consecutive odd numbers is 135. In that case, let x be the first number. Then
x + (x + 2) + (x + 4) + (x + 6) + (x + 8) = 135
5x + 20 = 135
5x = 115
x = 23
So the numbers are 23, 25, 27, 29, and 31.
If you really did mean 555 consecutive odd numbers summing to 135,135,135, the process is the same, but you would find a non-integer solution so that wouldn't be possible.

y = root(12)
4/(root(6)*root(12)) = 4/root(72) multiply top and bottom by root(72)
4root(72)/72 =root(72)/18

Hey there! :)
Answer:
g(3) = 11.
Step-by-step explanation:
Given g(x) = x² + 2
Plug '3' into 'x' to solve for g(3):
g(3) = (3)² + 2
g(3) = 9 + 2
g(3) = 11.
Answer: g(3)=8
Step-by-step explanation:
If g(x)=x2+2 and you wish to find g(3), you simply sub in the 3 from g(3) into the x from the original equation, making it g(3)=3x2+2. 3 times 2 is 6, plus 2 equals 8.

Answer:
7 teachers
Step-by-step explanation:
you decide 100 by 15 which equals 6.7 since you can't have half a teacher you round it to 7 teachers.
Answer:
The minimum number of teachers needed is 6
Step-by-step explanation:
To find minimum number of teachers we have to divide 100 and 15 so the answer is 6.666.....but if we
multiply 6 and 15 we get 90 , so it means that 6 teachers can only provide for 90 students , unfortunately there are 100
students , so we need 1 more teacher for the rest ten students that's why the answer came in decimal point . so the answer could be 6.66 or 7 .
