Add 25 and 6.25 then divide by 1.25 and it should give you n
9514 1404 393
Answer:
see below
Step-by-step explanation:
When doing this by hand, it can work well to start at the y-intercept (0, -2) and use the slope value to find additional points on the line. The slope of 5 indicates another point will be 5 units up for each 1 unit right from (0, -2). So, another point will be (1, 3).
Draw the line through the points you found.

A graphing calculator does this easily.
Given:
number of friends = 2 (Keith and Michelle)
total cost of meal plus tip = $53.70
total tip given = $9.60
Find: How much each friend paid for the meal excluding the tip.
Total amount paid : 53.70
less: total tip paid <u> - 9.60</u>
total cost of the meal: 44.10
divide: between 2 friends <u> ÷ 2 </u>
cost per friend 22.05
Keith and Michelle will each contribute $22.05 for the meal.
They will also contribute $4.80 each for the tip.
Each friend will contribute a total of $26.85 for the meal and tip.
Answer:
<u><em>Bet $100 and remove all non-face cards.</em></u>
Step-by-step explanation:
Each option may be answered on the basis of the ratio of face cards to non-face cards, which we'll say is R.
a. removing all of the black cards No. The vale of R does not change. R is the same for both black and red cards, so removing one color does not change R.
b. removing all non-face cards Yes. The only cards left are face cards. The odds of drawing 2 face cards in a row from this modified deck is 100%
c. removing all kings No. Face cards are being removed and will thus lower the probability of picking one.
d. removing all of the red cards No. Same reasoning as in (a.).
