Answer: 72 nickels and 15 quarters
Step-by-step explanation:
72 times .05 = 3.6 or $3.60
15 times .25 = $3.75
Total = $7.35
.05 is representing the nickels and .25 is representing the quarters and if you take a calculator and do 87-72 you get 15 and you can set it up yourself to double check. But I wouldn't recommend doing it with pennies that's how I got confused so many times and you can also give yourself a similar problem if you want to make sure you know how to do it. Sorry if this was confusing.
Kathy=k
John=k+6
''Together their ages equal four times Kathys age.''
→k+6+k=4k ; 2k+6=4k ; 2k=6 ;k=3
Kathy=3
John=3+6=9
Answer:
50%
Step-by-step explanation:
22 is half of 44.
So, this means 50% of 44 is 22.
The value of y, the length of each leg, must be greater than 7.

What is Isosceles triangle?</h3>
This is a type of triangle with two equal sides.
<h3>Rules for side length of triangles</h3>
- The sum of any two sides of a triangle must be greater than the third side.
Let the first, second and third side = a, b and c respectively
(b - a) < c < (a + b)
For an isosceles triangle with base of 14 units, the two other sides must be equal.
c < (a + b)
c = 14
a = b = y
14 < (y + y)
14 < 2y
7 < y
Thus, the value of y, the length of each leg, must be greater than 7.
