How do i solve this problem to this fraction 2/3-1/6

Answers

Find the common denominator of 3 and 6. which is 6. now just subtact 2 and 1 which is 1. ur answer is 1/6
You can do crisscross multiple.
2x6=12 then 3x1=3 than multiple the denominators 3x6=18 now you have 9/18 which can be simplified 9 goes into 9 one times and 9 goes into 18 two times. Your answer is 1/2. Hope this helps

The function c(x) = 3x − 4 determines how many cupcakes need to be purchased for a birthday party, where x is the number of kids at the party. The party planner uses d(c(x)) to find the amount of money to bring for the cupcake purchase. The function d(x) = 2x + 5. Solve for how much money to bring when there are 7 kids at the party.

Answers

Answer: $39

Step-by-step explanation:

Given: The function determines how many cupcakes need to be purchased for a birthday party, where x is the number of kids at the party. The party planner uses d(c(x)) to find the amount of money to bring for the cupcake purchase. The function

Now,

To find the amount of money to bring when there are 7 kids at the party, put x in d(c(x)), we get

Hence, the amount of money to bring when there are 7 kids at the party = $39

The answer of d(c(x))=39. hope it will help you

Three rectangular prisms have a combined volume of 518 cubic feet. Prism A has one-third the volume of Prism B, and Prisms B and C have equal volume. What is the volume of each prism?

Answers

Answer:  The volume of Prism A is 74 cubic feet, volume of Prism B is 222 cubic feet and the volume of Prism C is 222 cubic feet.

Step-by-step explanation:  Given that three rectangular prisms have a combined volume of 518 cubic feet. Prism A has one-third the volume of Prism B and Prisms B and C have equal volume.

We are to find the volume of each of the three prisms.

Let, a, b and c represent the volumes of Prism A, Prism B and Prism C respectively.

The, according to the given information, we have

a+b+c=518~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\n\na=(1)/(3)b~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)\n\nb=c~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(iii)

Substituting the values of a and c from equations (ii) and (iii) in equation (i), we get

a+b+c=518\n\n\n\Rightarrow (1)/(3)b+b+b=518\n\n\n\Rightarrow (1)/(3)b+2b=518\n\n\n\Rightarrow (b+6b)/(3)=518\n\n\n\Rightarrow 7b=1554\n\n\n\Rightarrow b=(1554)/(7)\n\n\n\Rightarrow b=222.

From equation (iii), we get

b=c=222,

and from equation (ii), we get

a=(1)/(3)*222\n\n\n\Rightarrow a=74.

Thus, the volume of Prism A is 74 cubic feet, volume of Prism B is 222 cubic feet and the volume of Prism C is 222 cubic feet.

  • The volume of Prism A is 74 cubic feet.
  • The volume of Prism B is 222 cubic feet.
  • The volume of Prism C is 222 cubic feet.

Further explanation

Given:

Three rectangular prisms have a combined volume of 518 cubic feet.

  • Prism A has one-third the volume of Prism B, and
  • Prisms B and C have equal volume.

Question:

What is the volume of each prism?

The Process:

Prism A has (1)/(3) the volume of Prism B. From the denominator 3, let us draw a diagram representing the volume of Prisms B and C, then Prism A. Remember, both prisms have the same volume.

Prism B: \boxed{\circ}\boxed{\circ}\boxed{\circ}

Prism C: \boxed{\circ}\boxed{\circ}\boxed{\circ}

Prism A: \boxed{\circ} or 1 of 3 units.

From all the diagrams above, it appears that the total units are 3 + 3 + 1 = 7 units.

Three rectangular prisms have a combined volume of 518 cubic feet. Therefore, we can calculate the volume of one unit diagram.

\boxed{ \ 7 \ unit = 518 \ cubic \ feet \ }

\boxed{ \ 1 \ unit = ? \ cubic \ feet \ }

Then \boxed{ \ 1 \ unit = (518)/(7) \ cubic \ feet \ }

Hence, \boxed{\boxed{ \ 1 \ unit = 74 \ cubic \ feet \ }}

And now, let us calculate the volume of each prism.

The volume of Prism A: 1 \ unit = \boxed{ \ 74 \ cubic \ feet \ }

The volume of Prism B:3 \ unit = 3 * 74 = \boxed{ \ 222 \ cubic \ feet \ }

The volume of Prism C:3 \ unit = 3 * 74 = \boxed{ \ 222 \ cubic \ feet \ }
