(not sure if this is right but)
x (to the 2nd power) + y (to the 2nd power) = cos (90) (to the 2nd power)
Answer:
the answer would be A
Step-by-step explanation:
(a) 3x=4(x-2.25) (or simplified: 3x=4x-9)
(b) 3x=4x-9
0=x-9
x=$9
(c) 3x9=27
4x9=36
36-9=27
and 27=27 therefore they spent the same and it is correct
(d) Tanya's items cost $9 each and Tony's items cost $2.25 less than this, or $6.75
Answer:
2) $25.01 3) $25.98
Step-by-step explanation:
2) 23.6 x 7% = 23.6 x .07 (move the decimal 2 places to the right) 23.6 x .07 = 1.652 but its money so round to $1.65 + 23.36 = $25.01
3) 24 x 8.25 = 24 x .0825 (again to the right twice) 24 x .0825 = 1.98+24 = 25.98
