Answer:
The number is 9.
Step-by-step explanation:
Lets write this as an equation first. We'll substitute the number for the variable <em>x</em>.
80 - 3x = 5x + 8
First, let's add 3x to both sides.
80 - 3x + 3x = 5x + 3x + 8
80 = 8x + 8
Next, let's subtract 8 from both sides.
80 - 8 = 8x + 8 - 8
72 = 8x
Finally, let's divide both sides by 8.
72/8 = 8x/8
9 = x
<em>"x" is 9.</em>
<em>So the secret number is 9.</em>

Answer:
305 and 793
Step-by-step explanation:
LCM * HCF = product
3965 * 61 = 241,865 = 5*13*61*61
HCF = 61 so
61*5 = 305
61 * 13 = 793
Answer:
Tyler is right
Step-by-step explanation:
Given that:
Lenght of wooden plank used = 3.5 feets
Placement of tick marks = 1 1/3 inches apart
Number of tick marks placed = 20
Recall:
1 foot = 12 inches
Hence, length of wooden post in inches :
3.5 * 12 = 42 inches on length
Total length covered by the ticks placed :
1 1/3 inches * Number of ticks placed
1. 333 * 20 = 26.6667 inches
Unmarked length = length of post - length covered by tickmark
Unmarked length = (42 - 26.6666) inches
Unmarked length = 15.3333 inches.
Hence,
Within 15 - 16 inches are yet to be marked.
