Freddies gas milage is 23 miles per galloon because 155.25 divided by 6.75 is 23
Step-by-step explanation:
Wai 1unit+45
Cheryl 1unit
Zheng 4units+180
Altogether 6units+225=510
6units = 510-225
6units=285
1unit=285÷6
= $47.5
So Wai =47.5+45 = 92.5
Cheryl =47.5
Zheng =4×47.5+180 =370
370-47.5=$322.5
Answer $322.5
<span>two divided by the difference of a number and 3 minus 4 divided by a number plus 3, equals 8 times the reciprocal of the difference of the number squared and 9.
let x=number
2/(x-3)-4/(x+3)=8/(x^2-9)=8/(x+3)(x-3)
LCD: (x+3)(x-3)
2(x+3)-4(x-3)=8
2x+6-4x+12=8
-2x+18=8
-2x=-10
x=5</span>
