Answer:
David=$8.8
Jo=$13.2
Mary=$22
Step-by-step explanation:
2+3+5=10
44/10=4.4
David=4.4x2=$8.8
Jo=4.4x3=$13.2
Mary=4.4x5=$22
8.8+13.2+22=44
Use this 3 following steps:
1)At first, we should find the roots :
3x+8=0 => x=-8/3
x-4=0 => x=4
2)Using a chart for the limits:

3)choose your solution:
[-8/3,-4)==> Sentence 3 is correct
Answer:
26
Step-by-step explanation:
→ Utilise Pythagoras theorem
a² + b² = c²
→ Substitute in the values
10² + 24² = c²
→ Simplify
100 + 576 = c²
→ Simplify further
676 = c²
→ Square root both sides to isolate c
26 = c
X/9=1
Multiply both sides by 9. So x=9.
In calculating
the average score, add the scores of each person and then divide it by the
number of scores present. In this problem, Tony has forty seven points for five
different quizzes. You are required to calculate for the average score of Tony.
The formula is A = T/n, where A is the average score, T is the score, and n is
the number of quizzes.
A = T/n
A = 47/5
<u>A = 9.4</u>

Therefore, Tony has an average of 9.4 points in five different
quizzes. </span>
