2.) No, tip amount is more than what the waiter usually receives
Step-by-step explanation:
2.) The amount of tip the waiter receives = 20% of total money.

Hello from MrBillDoesMath!
Answer:
The first choice (2x + 4y >=3, 2x +4y <=3)
Discussion:
Suppose a variable M met these conditions: M >=3 and M <=3. The only way this can happen is that M = 3. In our case letting M = 2x + 4y, we find the inequalities give
2x + 4y = 3
which is the equation of a line. (The other choices do NOT include the boundary line because they use strict < or > signs.)
Thank you,
MrB
Well, first you need to distribute the .5 to everything in the parenthesis. so you would come out with:
.5g + 5 = 50
now, you want to isolate the variable. so subtract 5 from both sides. You're left with
.5g = 45
now, divide 45 by .5
you're left with g = 90!
Answer:
504 millimeters (or 50.4 cm)
Step-by-step explanation:
- Width of key in student calculator = 14 millimeter (1.4 cm)
- Width of key in demonstration calculator = 2.8 cm
<u><em>Thus, the demonstration calculator's dimensions are </em></u><u><em>twice</em></u><u><em> that of students' (in cm)</em></u>
<u><em /></u>
Also given, student calculator height as 252 millimeters (25.2 cm)
Thus demonstration calculator height will be twice of that = 50.4 cm (or 504 millimeters)
