Answer:
<h2>x = 114</h2>
Step-by-step explanation:
0.2x – 1.8/5 = 4.2
0.2x - 1.8 = 4.2 (5)
x =<u> 21 + 1.8 </u>
0.2
x = 22.8 / 0.2
x = 114
Answer:
34 hours
Step-by-step explanation:
2:25 = x:425
25/2 = 12.5
425/12.5 = 34
so it is 34:425
She will need to read for 34 hours to read 425 pages
Answer:
5 cm
Step-by-step explanation:
The volume (V) of a cuboid is calculated as
V = lbh ( l is length, b is breadth and h is height )
Here l = 20, h = 12, V = 1200 and b is to be found, thus
20 × b × 12 = 1200, that is
240b = 1200 ( divide both sides by 240 )
b = 5
