Camillo needs 2,400 oz of jelly for the food challenge. If 48 oz of jelly cost $3.84, how much will Camillo spend on jelly? Expl
olga2289 [7]

My Answer:

Well he will spend I a lot I will say. But the steps to get to find out the answer are not that hard. The first step is to find out how much he needs. For this challenge he need 2,400 oz of jelly. Next we will divide that number by 48 oz. That number is how many jellies you will get if you spend $3.84. When you divide that you will get 50. Now you will multiply 50 and 3.84. After you multiply that you will get $192. That is how much Camillo is spending on jellies. I hope this has answerd your question

Another possible answer:

First, find the unit price of the jelly. The unit cost of jelly is $0.08 per ounce. Next, find the total price of 2,400 oz by multiplying the unit price by the quantity. The total price is $192.

Farmer brown has ostriches and llamas. Altogether she counts 98 feet and 33 heads. How many ostriches does she have?
Ronch [10]

Answer: She has 17 ostriches.

Step-by-step explanation:

We know , ostrich has 2 legs where as llama has 4 legs.

Let x be the number of ostriches and y be the number of llamas.

Then, as per given , we have the following linear equations :

2x+4y=98---(i)\\\\ x+y=33---(ii)

Multiply 2 to eqn (ii) , we get

2x+2y=66---(iii)\\

Subtract (iii) from (i) , we get

2y=32\\\Rightarrow\ y=16

Put this in (ii) , we get x+16=33\Rightarrow\ x=17

Hence, there are 17 ostriches and 16 llamas.

PLEASE HELP ME!!! ILL GIVE THE FIRST PERSON BRAINLIEST!!!

Problem 2

Midpoint: Think 1/2. A midpoint cuts a line segment in 1/2 (in this question). That means that the left segment = the right segment. Remember: midpoint means 1/2.

LN is given as 14.

LM is 1/2 the distance of 14

LM = 1/2 * 14

LM = 7

Problem 3

If the midpoint = the 1/2 way point, the two halves are equal. Remember a midpoint divides the 2 parts into 2 EQUAL parts.

4a - 2 = 18          Add 2 to both sides

4a = 18 + 2

4a = 20

a = 20 /4

a = 5

Problem 4

Remember that midpoint means 1/2. That a midpoint cuts a segment into 2 equal segments

Equation

2n + 2 =  5n - 4      

Solve

2n + 2 = 5n - 4      Add 4 to both sides

2n + 2 + 4 = 5n     Subtract 2n from both sides.

6 = 5n - 2n

6 = 3n                    Divide both sides by 3

6/3 = n

n = 2

<u>Answer:</u> B

Problem 5

And again the whole line segment is divided into 2 equal parts.

<u>Equation</u>

6p - 12 = 4p           Add 12 to both sides

6p = 12 + 4p           Subtract 4p from both sides.

6p - 4p = 12

2p = 12                   Divide by 2

p = 12/2

p = 6           <<<<< Answer
