Answer:
Step-by-step explanation:
- Initial number = 10
- Weekly growth rate = 15% or 1.15 times
<u>Equation for this relationship:</u>
- V(t) = 10*1.15^t, where t - number of weeks
<u>Number of views in 5 weeks:</u>
- V(5) = 10*1.15^5 = 20 views (rounded)
<h3>Answer:</h3>
12 students
<h3>Explanation:</h3>
40% earned a B; 20% earned an A, so (40%+20% =) 60% got a "B or better."
60% of 20 students is ...
... 60/100 × 20 students = 1200/100 students = 12 students

Answer:
(3,-3) or x = 3
Step-by-step explanation:
I solved this problem with the help of graphing, you would start by sketching each equation. The x-value of the point where both equations intersect would be solution to your equations.
Answer:
x =25
Step-by-step explanation:
<M + <R = 180
We know M = 5x+10 R = 45
Substituting these values in
5x+10 + 45 = 180
Combine like terms
5x+55 = 180
Subtract 55 from each side
5x+55-55 = 180 -55
5x = 125
Divide each side by 5
5x/5 = 125/5
x = 25
