Answer:
4x
Step-by-step explanation:
Answer:
Jesicaa=$59
Ashley=$71
Devyn=$98
Step-by-step explanation:
Let Jessica's earning be x:
![Jessica=x\\\\Ashley=x+12\\\\Devyn=2x-20](https://tex.z-dn.net/?f=Jessica%3Dx%5C%5C%5C%5CAshley%3Dx%2B12%5C%5C%5C%5CDevyn%3D2x-20)
-Given that the total earnings for the three was$228. earnings per person is calculated as:
#Equate their earnings to the 228 to solve for x:
![x+(x+12)+(2x-20)=228\\\\4x-8=228\\\\4x=236\\\\x=59](https://tex.z-dn.net/?f=x%2B%28x%2B12%29%2B%282x-20%29%3D228%5C%5C%5C%5C4x-8%3D228%5C%5C%5C%5C4x%3D236%5C%5C%5C%5Cx%3D59)
#Substitute for x in each earning equation to determine individual earnings:
![Jessica=x=59\\\\Ashley=x+12=59+12=71\\\\Devyn=2x-20=59\times 2-20=98](https://tex.z-dn.net/?f=Jessica%3Dx%3D59%5C%5C%5C%5CAshley%3Dx%2B12%3D59%2B12%3D71%5C%5C%5C%5CDevyn%3D2x-20%3D59%5Ctimes%202-20%3D98)
Answer:
B: 304in^2
Step-by-step explanation:
One triangle face: (8)(15) ÷ 2 = 60
Four triangle faces: 60 x 4 = 240
Bottom Face: (8)(8) = 64
Total Surface Area: Four triangle faces + Bottom Face
Total Surface Area: 240 + 64
Total Surface Area: 304in^2
146.66 because you have to subtract then divide
