Answer: there were 692 visitors on Saturday.
Step-by-step explanation:
Let x represent the number of visitors that were there on Friday.
Let y represent the number of visitors that were there on Saturday.
Let z represent the number of visitors that were there on Sunday.
The theme park had 1099 visitors in 3 days. It means that
x + y + z = 1099- - - - - - - - - - - - - -1
There were twice as many visitors on saturday than on Friday. This means that
y = 2x
x = y/2
There were 234 more visitors on Sunday than on Saturday. This means that
z = y + 234
Substituting x = y/2 and z = y + 234 into equation 1, it becomes
y/2 + y + y + 234 = 1099
Cross multiplying by 2, it becomes
y + 2y + 2y + 468 = 2198
5y = 2198 - 468
5y = 1730
x = 1730/5
x = 346
y = 2x = 2 × 346
y = 692
z = y + 234 = 692 + 234
z = 926
Answer:
8
Step-by-step explanation:
2log(x)=log(64)
By logarithms properties
log(x²)=log(64)
When you have log or ln in both sites, you delete them and...
x²=64
![\sqrt[]{x^{2} } =\sqrt{64} \\x=8](https://tex.z-dn.net/?f=%5Csqrt%5B%5D%7Bx%5E%7B2%7D%20%7D%20%3D%5Csqrt%7B64%7D%20%5C%5Cx%3D8)
Answer:
85%
Step-by-step explanation:
9+51 = 60
(51/3) ÷ (60/3) = 17/20
(17/20)% = 85%
