Answer:
(a) 3d=81
(b) 27
Step-by-step explanation:
every day, kojo write 3 pages
number of days he has written his story= d days
therefore number of pages he has written= 3d
from the final sentence,
3d= 81
<h3>(a) the equation to describe the situation: </h3><h3>3d= 81</h3>
(b) number of days kojo has been writing his story
3d= 81
dividing through by d
3d/3= 81/3
d = 27
<h3>therefore number of days = 27</h3>
Answer: 6
-3x-8=10
-3x=18
x=6
When g(x) is equal to 10, x is equal to 6. So, g(6)=10
Answer:
Area of a circle- <em>pi </em>x <em>r </em>square
3.14 x 2 x 2
= 3.14 x 4
= 12.56
Round off- 13
Pythagorean theorem(√82)^2 = 9^2 + x^2
x = 1 cm
15^2 = 9^2 + y^2
y = 12 cm.
12-1 = 11
Area = 9*11 = 99 cm^2
