Answer:
Step-by-step explanation:
Let x represent the number of videos viewed using either plan A or plan B.
Let y represent the cost of viewing x videos using plan A.
Let z represent the cost of viewing x videos using plan B.
Plan A: $3 per video viewed, plus a flat rate of $8 per month. This means that the cost of viewing x videos would be
y = 3x + 8
Plan B: $5 per video viewed and no additional flat rate. This means that the cost of viewing x videos would be
z = 5x
The inequality to determine when the cost of viewing n videos using Plan A is less than the cost of viewing n videos using Plan B would be
3x + 8 < 5x
8 < 5x - 3x
8< 2x
4 < x
x > 4
Answer: After 12 weeks they will both be at the dentists on the same Tuesday
Step-by-step explanation:
Since we have given that
He goes for a checkup every fourth Tuesday and his friend goes for a check up every third Tuesday.
We need to find the number of weeks they both will be at the dentist on the same Tuesday.
For this we will find "L.C.M. of 4 and 3 " =12
So, After 12 weeks they will both be at the dentists on the same Tuesday.
The numerator and denominator of your answer is realtead to the model because the denominator is all of the parts and the numerator is the parts crossed out or shaded.
Answer:
160 ft^2
Step-by-step explanation:
First you have to find the width, then you find the area. To find the width with a percentage we do Part/ Total = %/100 and we cross multiply. We need to find the part so that is the unknown, we will call it 'w' for width
w/20 = 40/100 Now we cross multiply, the x and the 100 and the 20 and 40
w * 100 = 100w
20 * 40 = 800
Now we have 100w = 800 The next step is to divide both sides by 100 so we just have w
100x/100= w
800/100 = 8
w = 8
The width is 8
Now we find the area which is length x width
20 x 8 = 160
So the area is 160 ft^2
