The three positive integer that has mean of 5 and range of 10 will be 0, 5, 10.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Let the three positive number be (a – d), (a), and (a + d).
Then the mean of the number will be 5. Then we have
5 = (a – d + a + a + d) / 3
5 = (3a) / 3
a = 5
Then the range will be 10. Then we have
(a + d) – (a – d) = 10
a + d – a + d = 10
2d = 10
d = 5
Then the three positive integer that has mean of 5 and range of 10 will be 0, 5, 10.

<h3>Given:</h3>
<h3>To find:</h3>
How much is $100 in ZA rands.
<h3>Solution:</h3>
Let the unknown be "x"
We'll have to do cross multiplication.
So we'll have to multiply 100 and 17.

Answer:
y = 8x
Step-by-step explanation:
When the number of people increased by 10, the caterer charged an additional $80. Therefore, we estimate that the cost per person is $8. In order to verify:
$8/person * 15 people = $120. True. $8/person * 25 people = $200. True.
Therefore, if we let x represent the number of people being cater for and y represent the cost, the equation to model the situation is simply y = 8x.
hope it helps!
