Answer:
1 and 3
Step-by-step explanation:
Step 1 is clearly elaborated. Tax is impliedd on the discounted price.
In step 3, the steps of deductions are skipped.
Like 1 + 10% = 110% and 1 - 20% = 80%
Step 2 is simply wrong. Because the percentages are implied on different values.
Answer:
All you do is replace the variable with the numbers given to replace them.
So your new equation is 10-4(2) this was given to you C=10 , D=2
Okay, let's solve it 10-4(2)
4*2 equals 8 so now it's 10-8
10-8

Answer:
1.80m + 3 ≤ 25
Step-by-step explanation:
We have a flat rate of $3, which means that's the base value. Now, we see that Jennifer has to pay $1.80 per mile, which means that when she has ridden m miles, she has to pay 1.80m. However, remember to add 3 to this:
1.80m + 3
Jennifer only has $25 to spend, so she can't spend any more than 25. This means that the money she can spend must be less than or equal to $25:
1.80m + 3 ≤ 25
Hope this helps!
Answer:
Step-by-step explanation:
y= -(1/2)x - 5
Answer:

Step-by-step explanation:
Let A and B events. We have defined the probabilities for some events:

Where A' represent the complement for the event A
The complement rule is a theorem that provides a connection between the probability of an event and the probability of the complement of the event. Lat A the event of interest and A' the complement. The rule is defined by:
So for this case we can solve for P(A) like this:

And now we can find
using the total probability rul given by:

And if we replace the values given we got:

And that would be the final answer.
