Each page from 10 to 99, inclusive (so total of 90 pages) needs two digits (for example page 12 needs two digits: 1 and 2); Each page from 100 to 200, inclusive (so total of 101 pages) needs three digits (for example page 123 needs three digits: 1, 2 and 3)
The quadrilateral have equal opposite sides, for example:
Then, (4x + 6) must be equal to (7x - 3), and (4y - 3) is equal to (3y + 1), therefore
We can solve that equation for x
Hence, x = 3. Now let's solve the other equation
Then the value of y is 4.
Final answers:
x = 3
y = 4
39.5 %
39.5 / 100
39 1/2 / 100
79/2 / 100
79 / 200
Answer:
126
Step-by-step explanation:
A Nonagon has 9 sides. To answer this, the polygon has to be regular.
The Perimeter is 9*14 = 126
This is an expression if she only gets pedicure
y = 35
If she wants to get massage, multiply the cost for a minute with the number of minutes.
Find cost per minute first
cost = 50/20
cost = 2.5
So the expression would be
y = 35 + 2.5x
y = 2.5x + 35
