Answer: (88+x)/2

Explanation: In order to find average, add all the numbers and divide it by how many numbers you added. So,

(88 + x)/2

Nothing else was given so I could only find this equation.

Brainliest please if I am correct. Hope it helped!

LUCKY_DIMON [66]

Answer:

Step-by-step explanation:

Having the information on how many events there are and how many people in each event there would help me personally solve this

what i can tell you is its a probability thing a tree diagram is starting with something, like flipping a coin, and creating a branch for heads and tails, 0.5 for each branch. like the attachment I have on here. there's only 2 probable results from a coin, but if I have 5 events with 50 competitors I've created a lot more probable outcomes, it also depends on the events, if one of my competitors in 6'9" and ones 5'2" and the event is a dunk contest it would be slightly unfair and the probability of the person who is 5'2" changing your tree diagram :)

Question 10
kozerog [31]

The regular selling price per unit for the laptop is $298.6.

<h3>How to calculate the price?</h3>

Let the regular price per unit be x.

The expense is 19% of the selling price and profit is 25% of the selling price. This will be illustrated as:

x + (19% × x) + (25% × x) = 430

x + 0.19x + 0.25x = 440

1.44x = 430

Divide

x = 430 / 1.44

x = 298.6

The price is $298.6

Answer:

165 is greater than or equal to 17.75x+5.25; 9 is greater than or equal to x

Step-by-step explanation:

The problem states that they have no more than $165. This means that they either use all the money, or they have leftover money, which means you need to use the 'greater than or equal to' sign. It says that tickets are $17.75 a person, and we're trying to find the number of people (x). You can write this as 17.75x. There is also a parking fee to add on to the equation, which is represented as +5.25. Now, we can solve!

I'm going to use an equal sign to replace the inequality symbol, but make sure to add the symbol at the end of the problem.

165=17.75x+5.25

159.75=17.75x

9=x

Our final answer is 9 is greater than or equal to x. Hope this helps!

one third of a land is on maize, a fifth of the remainder is on potatoes and the rest which is 0.5 ha is on beans. how much of t
disa [49]

Answer: 1250\ m^2

Step-by-step explanation:

Let x= Total land.

Then for Maize = \dfrac{x}{3}    

For Potatoes = \dfrac15(x-\dfrac {x}{3})=\dfrac15(\dfrac{2x}{3})=\dfrac{2}{15}x

For beans = x- (\dfrac{x}{3}+\dfrac{2}{15}x)=0.5 \ ha

\Rightarrow\ x- (\dfrac{5x+2x}{15})=0.5 \ ha\\\\\Rightarrow\ x- (\dfrac{7x}{15})=0.5 \ ha\\\\\Rightarrow\  \dfrac{15x-7x}{15}=0.5 \ ha\\\\\Rightarrow\  \dfrac{8x}{15}=0.5 \ ha\\\\\Rightarrow\  x=0.5\times\dfrac{15}{8} \ ha\\\\\Rightarrow\  x=0.9375 \ ha

1 ha = 10000.00 m²

0.9375 ha = 9375 m²

Land for potatoes = \dfrac{2}{15}(9375) =1250\ m^2

Hence, 1250\ m^2 of the land is on potatoes.
