The concept of determining which reactant is limiting and which is in excess is akin to determining the number of sandwiches tha

Alona [7]

Answer: There are 22 whole cheese sandwiches that can be prepared.

Step-by-step explanation:

Since we have given that

Number of slices of bread = 44

Number of slices of cheese = 75

According to question, a cheese sandwich consists of 2 slices of bread and 3 slices of cheese.

So, we need to find the number of whole cheese sandwiches that can be prepared.

Number of sandwich containing only slice of bread is given by

$\dfrac{44}{2}=22$

Number of sandwich containing only slice of cheese is given by

$\dfrac{75}{3}=25$

As we know that each sandwich should contain both slice of bread and slice of cheese.

So, Least of (22, 25) = 22

Hence, there are 22 whole cheese sandwiches that can be prepared.

14+14p=21 solve for p

11Alexandr11 [23.1K]

Answer: 0.5

Step-by-step explanation: In this problem, we're asked to solve the following equation for p. Let's first switch 14 and 14p around so we have 14p + 14 = 21.

To solve this equation for p, we must first isolate the term containing p which in this case is 14p.

Since 14 is being added to 14p, we need to subtract 14 from both sides of the equation.

14p + 14 = 21

-14 -14

On the left side of the equation, the positive 14 and negative 14 cancel each other out and we have 14p. On the right side of the equation, we hav 21 - 14 which gives us 7.

Now we have the equation 14p = 7.

Since p is being multiplied by 14, to get p by itself, we divide both sides of the equation by 14.

On the left side of the equation the 14's cancel and we are left with p. On the right side of the equation, 7 divided by 14 is 0.5 which is our answer.

Therefore, p = 0.5 which is the solution for our equation.

Remember, you can always check your solution by substituting a number in for a variable to make sure the equation is true.

students in each van = 7
number of vans used = unknown; x

The number sentence that can be used to find out how many vans are needed to take the students to the game is:

7 * x = 56

x = 56/7
x = 8 vans needed.
