Given:
Triangle EFG and EHG are two right triangles.
To find:
The values of x and y.
Solution:
In triangle EFG,
[Angle sum property]
In triangle EHG,
[Angle sum property]
Therefore, the value of x is 25 and the value of y is also 25.
Start off by finding 18% of 13.90.
18%=18/100=0.18
0.18(13.9)=2.5
An 18% tip would be $2.50.
Now, to find out if Lana has enough money, add $2.50 to $13.90 to find out the total amount she would leave. You get $16.40. Since $16.40>$15, the answer is no because the total cost including the 18% tip is greater than $15.
First, distribute the 2.
2(3p+1)>-4
6p+2>-4
Second, subtract 2 from both sides.
6p+2>-4
-2 -2
_______
6p > -6
Third, divide both sides by 6.
6p > -6
--- ---
6 6
______
p>-1
So the answer is p>-1.
10 - (y - 6) - y
10 - y - 6 - y
10 - 6 - y - y
4 -2y
