Answer:
A
Step-by-step explanation:
Given
= 8 + 4A
Multiply through by 3 to clear the fraction
2A = 24 + 12A ( subtract 12A from both sides )
- 10A = 24 ( divide both sides by - 10 )
A = - 2.4 → A
Look at the left side of the polygon. Since they are both real numbers, we can use those to set up a proportion:
16:12=(x-1):6
Now, we can cross multiply and solve:
96=12(x-1)
96=12x-12
108=12x
9=x
The value of x is 9

Answer:
75 %
Step-by-step explanation:
To solve for the above question,
The percentage of pupils that submitted their project on time
= Number of pupils that submitted their project on time/Number of pupils × 100

Number of pupils = 40 pupils
= 30/40 × 100
= 75 %
The percent of the pupils that submitted their project on time is 75%
