A sandwich store charges a delivery fee to bring lunch to an office.

Delivery cost - D

Meatball sandwich cost  - M

One office pays $40.50 for 5 meatball sandwiches.

40.50 = 5M + D

Another office pays $66.50 for 9 meat ball sandwiches

66.50 = 9M + D

A. How much does each meatball sandwich add to the cost of delivery?

D = 40.50 - 5M = 66.50 - 9M

40.50 - 5M = 66.50 - 9M

9M - 5M = 66.50 - 40.50

4M = 26.00

M = 6.50

B. What is the delivery fee

D = 40.50 - 5M = 40.50 - 5(6.50) = 40.50 - 32.50 = 8.00

Check

66.50 = 9M + D = 9(6.50) + 8 = 58.50 + 8.00 = 66.50

Answer:

x=2, z=62

Step-by-step explanation:

Since (14x+34) and (11x+96) are linear angles, their angle measures must add to 180 degrees. We can thus set up this equation:

14x+34+11x+96=180

25x+130=180

25x=50

x=2

Since z and (14x+34) are vertically opposite angles, their values must be equal. Thus:

z=14x+34=14(2)+34=28+34=62

Which type of graph is useful for demonstrating how something changes or fluctuates in value over time?
netineya [11]

Line graphs (or line charts) are best when you want to show how the value of something changes over time, or compare how several things change over time relative to each other. Whenever you hear that key phrase “over time,” that's your clue to consider using a line graph for your data.

According to the National Retail Federation, the average shopper will spend $1,007.24 during the holiday shopping season. What i
Mazyrski [523]

Based on the amount predicted to be spent, the hypotheses will be:

  • Null Hypothesis = $1,007.24
  • Alternate Hypothesis ≠ $1,007.24

The Null Hypothesis is the one that confirms the prediction so in this case it will be that the average shopper will indeed spend $1,007.24.

The Alternate Hypothesis theorizes that the event being predicted will not happen so in this case that would mean that the shopper would not spend $1,007.24.

In conclusion, the null hypothesis confirms and the alternate denies.
