Answer:
18 Weeks
Step-by-step explanation:
$39.50=17 + (5*x)
$39.50-17=17-17 + (5*x)
$22.5/5=(5*x)/5
It will take 4.5 months to save up. If each month has 4 weeks it will take 18 weeks
He would have to work 17 hours.
Answer: the other two sides are 5 feet and 12 feet
Step-by-step explanation:
Length of one side be x , that means the other side is x + 7
by Pythagoras theorem:
+
= 
expanding , we have:
+
+ 14x + 49 = 169
+ 14x + 49 - 169 = 0
+ 14x - 120 = 0
divide through by 2 , we have
+ 7x - 60 = 0
By factorizing , we have
(x - 5)(x+12) = 0
Therefore:
x = 5 or x = -12
Since , the side can not be negative , so
x = 5
That means the other side will be 5+ 7 = 12
Problem 1
1 ft = 12 inches
2 ft = 24 inches (multiply both sides by 2)
Multiply by 1/3 to get (1/3)*24 = 24/3 = 8
<h3>Answer: 8 inches</h3>
========================================
Problem 2
1 yard = 3 feet
3 yards = 9 feet (multiply both sides by 3)
1 ft = 12 inches
9 ft = 108 inches (multiply both sides by 9)
so overall, 3 yards = 108 inches
Multiply this by 1/6
(1/6)*(108 inches) = 108/6 = 18 inches
<h3>Answer: 18 inches</h3>
note: 18 inches = 12 inches + 6 inches = 1 ft, 6 inches = 1.5 ft
