y=x4−7; y=2
Y=2 (2)=x.4-7
2+4x-7
4x-7=2 get the variable alone by doing the same thing to both sides
4x=9
4x/4=9/4
y=9/4
x=9/4
Since Barb has 9 and Trisha has 3 times as many you can use the equation 9x3 which equals 27

Answer:
745.31
Step-by-step explanation:
1. 12.5^2 * 2 = 312.5
2. (3,14 * 156,25)/2 = 245.31
3. (30 * 12.5)/2 = 187.5
4. 187.5 + 245.31 + 312.5 = 745.31
