All you have to do is make a equation. Which would be p5+3 =v  the answer should be 8 because if you plug 8 in you get (8)5+3=v  40+3= 43 then you add 8 to 43 and get 51 so i believe the answer to your question is 8

Answer: There are 8 pepperoni pizzas she order.

Step-by-step explanation:

Since we have given that

Number of vegetable pizzas and pepperoni pizzas for the eighth grade party = 51

Let the number of pepperoni pizzas be 'p'.

Let the number of vegetable pizzas be 'v'.

According to question,

v=5p+3

So, it becomes,

v+p=51\\\\5p+3+p=51\\\\6p+3=51\\\\6p=51-3\\\\6p=48\\\\p=\dfrac{48}{6}\\\\p=8

Hence, there are 8 pepperoni pizzas she order.

Rasek [7]

Answer:

The answer to your question is 10.7 units

Step-by-step explanation:

To solve this problem, just calculate the distance from the House to the Library, then the distance from the Library to the Post office and finally to the Post office to the house.

I hope this helps! Also, pls mark me as the brainliest!

AlSO IF YOU WANT THE STEP BY STEP EQUATION IT IS--->

dHL = \sqrt{(-2 + 3)^{2} + (-2 - 2)^{2}}

dHL = \sqrt{(1)^{2}+ (-4)^{2}}

dHL = \sqrt{17} = 4.1

dLP = \sqrt{(-2 -2)^{2} + (-2-2)^{2}}

dLP = \sqrt{(-4)^{2} + (-4)^{2}}

dLP = \sqrt{32} = 5.7

dPH = \sqrt{(2 + 3)^{2}+ (2 - 2)^{2}}

dPH = \sqrt{(5)^{2}+ (0)^{2}}

dPH = \sqrt{25}

dPH = 5

Minimum distance = 4.1 + 5.7 + 5

Minimum distance = 10.7

A farmer from Whidbey Island: A man claims his whalebone can detect water. You design an experiment using a set of 4 cans, 3 emp
tatyana61 [14]

Answer:

The value is E(x) =  1.25

Step-by-step explanation:

From the question we are told that

The number of cans is n = 4

The number of can that are empty is N = 3

The number of can filled with water is k = 1

The number number of sets of cans is w = 5

Generally probability of detecting the correct can is mathematically represented as

p  =  \frac{k}{n}

=> p  =  \frac{1}{4}

=> p  = 0.25

Generally probability of not detecting the correct can is mathematically represented as

q =  1- p

q =  1- 0.25

q = 0.75

Generally the number of cans expected of the farmer to correctly identify by chance is mathematically represented as

E(x) =  w  *  p

=> E(x) =  5  * 0.75

=> E(x) =  1.25

Let u=  (-1,3) and w =(2,4) Find the resulting vector of 2u-4w  in component form..
IgorLugansk [536]
Very simple. You just use the vectors as normal numbers, and multiply the coordinates with 2 and 4 like this: 

2*u = 2* (2,4) = (4,8)
4*w = 4* (-1,3) = (-4,12)

(4,8) - (-4,12) = (8,-4)

So the vector has the coordinates (8,-4)

Please solve and show steps for both 23 and 24
const2013 [10]
23. The answer is D. If you multiply 0.8 by 5 you get 4 meters which means it would take 5 minutes. Multiplying it by 5 will give you a whole number therefore easier to find on the graph.

24. The answer is G. The square root of 5 is 2.23 and the square root of 2 is 1.4
