Answer:
B. 0
Step-by-step explanation:
If you subtract the right side expression and simplify, you get ...
4/5(20x +5) -(16x -2) = 0
16x +4 -16x +2 = 0
6 = 0 . . . . . . . . . . . . false
There is no value of x that will make this true. There are no solutions.
Answer:multiply 2.50 by 25 I think
Step-by-step explanation:
Well, they are equivalent, but I'm not sure if that's exactly what you're asking. :)
To find 10% divide by 10 so 1.07 or round to 1.08 if you like then double to
get 20% so 2.14 or 2.16 so if the bill is 10.75 you would pay 12.89 with a 20% tip
Answer:
No
Step-by-step explanation:
We know that the 3-4-5 and 9-12-15 right triangles are similar. If you add 6 units to the length of each side of both of these triangles, you obtain 9-10-11 and 15-18-21 triangles, which are not similar since 9/15 is not equal to 10/18.
