Answer:
The solution of the inequality is a < 0.2870
Step-by-step explanation:
* Lets talk about the exponential function
- the exponential function is f(x) = ab^x , where b is a constant and x
is a variable
- To solve this equation use ㏒ or ㏑
- The important rule ㏒(a^n) = n ㏒(a) OR ㏑(a^n) = n ㏑(a)
* Lets solve the problem
∵ 13^4a < 19
- To solve this inequality insert ㏑ in both sides of inequality
∴ ㏑(13^4a) < ㏑(19)
∵ ㏑(a^n) = n ㏑(a)
∴ 4a ㏑(13) < ㏑(19)
- Divide both sides by ㏑(13)
∴ 4a < ㏑(19)/㏑(13)
- To find the value of a divide both sides by 4
∴ a < [㏑(19)/㏑(13)] ÷ 4
∴ a < 0.2870
* The solution of the inequality is a < 0.2870
Well it would make sense that Jenny had 6 marshmallows and Julie did not put any in, Hope this helped a little
Answer:
Cost of dinner: $10.85
Money to add: $1.40
Step-by-step explanation:
1. Calculate the cost of the chicken and broccoli: 3(3.15)+1(1.40)=$10.85
2. Subtract Jared's money from the cost of dinner: $10.85-$9.45=$1.40
The answer is 6 inch sandwiches. You will have 7 sandwiches.
