Answer:
5 cakes
Step-by-step explanation:
13 1/3 ÷ 2 2/3
40/3 x 3/8
= 5 cakes
You might have made an error the first time you solved for x. I got x = -0.5.
When you have your log base 4, the way you cancel that out is by making 4 the base on both sides, so you get 4^(log4) to reduce to 1, and you're left with:
2x + 3 = 4^(1/2) ... Simplify
2x + 3 = 2
2x = -1
x = -1/2
If you plug that back in, everything checks out. Maybe double check your use of logarithm/exponent properties?
The answer is C. Because if g equals 4 you multiply 11 times 4 to get 44 then it is a quite simple problem 44 + 5 = 49
In decimal form that would be 36.052
Standard Form: 79,031
Expanded Form: 70,000 + 9,000 + 30 + 1
