You can square the whole problem to cancel out the square root. Might make things easier.
A <u>reasonable tip </u>would be $5.00
Rosita paid $27.08 an wants to tip a whole dollar <u>closest to 20%. </u>
The first step is therefore to find out 20% of $27.08.
= 20% x 27.08
= $5.42
The closest whole dollar depends on the first decimal point.
If it is 5 and above, the tip would be $5 as we would round down.
If it is 4 and below, the tip would be $6 as we would round up.
The<u> first decimal </u>is 4 so we would round down to $5.00
The tip would therefore be $5.00

Would be the correct answer because you can't add the two values together, they both need to have 'x' to be able to.
Step-by-step explanation:
1. 4 3/4=19/4
53/2=13/2
the total change of square will be. 19/4 + 13/2= 19+26/4=45/4
2. total change is 0.7+0.4=1.1
3.-7 1/6= -43/6
3 5/6= 23/6
-43/6 + 23/6 =-20/6 = -10/3
4. metals=2.625(m)
paper=5.58(p)
glass= x
total = 9.5(t)
m + p + x = t
2.625 + 5.58 + x =9.5
8.205 + x = 9.5
x = 9.5 - 8.205
x = 1.295
