Answer:
Lisa spends $138.40 on school lunches in 16 weeks.
Step-by-step explanation:
You have to multiply 8.65 by 16, since 8.65 is how much money Lisa spends each week for lunch, then you multiply by 16 since the problem calls for 16 weeks, then you get your final answer of $138.40.
Answer: The first option.
Step-by-step explanation:
1. You need to remember that:
- An even function is a function with the following property:
f(-x)=f(x)
- An odd function is a function with the following property:
f(-x)=-f(x)
2. By definition, the contangent is an odd function, therefore you have that:
cot(-θ)=-cot(θ)
Then:
3. So, you can coclude that the first step is wrong. Therefore, the answer is the first option.
Step-by-step explanation:
Vamos resolver sua equação passo a passo.
10-7c=10+2(3-5c)
Etapa 1: simplifique os dois lados da equação.
10-7c=10+2(3-5c)
10+-7c=10+(2)(3)+(2)(-5c)(Distribuir)
10+-7c=10+6+-10c
-7c+10=(-10c)+(10+6)(Combine os termos semelhantes)
-7c+10=-10c+16
-7c+10=-10c+16
Etapa 2: adicione 10c a ambos os lados.
-7c+10+10c=-10c+16+10c
3c+10=16
Etapa 3: subtraia 10 de ambos os lados.
3c+10-10=16-10
3c=6
Etapa 4: divida os dois lados por três.
