This is a simple question, where the calculation has to be done with clarity for understanding.
Let us assume the unknown number = x
Then we can write the equation as
120x/100 = 160
120x = 160 * 100
120x = 16000
x = 16000/120
= 1600/12
= 133.33
So the unknown number is 133.33. It is not a perfect result but on approximation it can be seen that it is the nearest answer that can be reached. I hope the procedure of doing such problems is clear to you.
For the total costs to be the same a pair of skis must be rented for 3 hours.
Two shops rent pairs of skis for a rental fee plus a fee per hour.
Let, the number of hours must a pair of skis be rented = x
Equation for Shop A,
3 + 9x equation 1
Equation for Shop B,
9 + 6x equation 2
Total cost for Shop A and Shop B is same so we can equate equation 1 and equation 2 as mentioned below:
3 + 9x = 9 + 6x
3x = 6
x = 3
Thus we can write, for the total costs to be the same a pair of skis be rented for 3 hours.

3 balls of wool would make 6 hats.
The value of x is 34. Since segment ED bisects the triangle, it makes both of the sides equal. Segment GD equals 35 cm which mines Segment DH should also equal 35cm. When you plug in x with 34, (34+1)cm that equals 35cm
Step-by-step explanation:
3. Slope is postive
x1=6
x2=3
y1=10
y2=6
m=6-10/3-6
m=4/3
y=mx+b find b
10=4/3*3+b
10=4+b
b=6
y=4/3x+b
4.slope is zero
y=b
Y=3
