Answer:
The original price was $40
Step-by-step explanation:
let x = original price
34= 0.85x
Divide both sides by 0.85
34/0.85 = x
40 = x
Check:
0.15 × 40 = 6
40 – 6 = 34

Satara was having fun playing poker. She needed the next two cards dealt to be hearts so she could make a flush (five cards of the same suit). There are 10 cards left in the deck, and three are hearts. What is the probability that the two cards dealt to Satara (without replacement) will both be hearts? Answer choices are in percentage format, rounded to the nearest whole number.
Answer:
7%
Step-by-step explanation:
Given the following :
Total Number of cards left in deck = 10
Number of hearts left in deck = 3
Probability = (required outcome / Total possible outcomes)
Required outcome = hearts card in deck
Two cards are to be dealt to Satara without replacement :
Probability of 1st card being hearts :
P(1st card being hearts) = required outcome / Total possible outcomes
P(1st card being hearts) = 3 / 10
Probability of 2nd card being hearts :
Since it is without replacement :
Required outcome = (3 - 1). = 2
Total possible outcomes = (10 - 1) = 9
P(2nd card being hearts) = 2 /9
Probability of the two cards being hearts :
(3 / 10 × 2/9) = 6 /90 = 0.0666
0.06666 × 100% = 6.66%
= 7% (nearest whole number)

t-(-5) = 9
what’s the first step to solve the equation?
Answer:
Subtract 5 from each side
( or add -5 to each side)
Step-by-step explanation:
t-(-5) = 9
t+5 = 9
Subtract 5 from each side
t +5-5 = 9-5
t = 4
The freezing temperature of the water is 32 degrees Fahrenheit and the boiling temperature of water is 212 degrees Fahrenheit. Write an absolute value equation that represents the minimum and maximum temperature of liquid water. Use X to represent the temperature.
Answer:
90 = | x - 122 |
Step-by-step explanation:
Given;
maximum temperature, 212 °F
minimum temperature, 32 °F
First, determine the difference of both values;
212 - 32 = 180
Divide this value by 2
180/2 = 90
90 = | x - 212 + 90|
90 = | x - 122 |
where;
x is the temperature of water
Thus, the absolute value equation that represents the minimum and maximum temperature of liquid water is 90 = | x - 122 |

Due to the Triangle Angle Sum Theorem, we know that the sum of the interior angles of a triangle is 180 degrees.
90 + 2x - 2 + x + 5 = 180 degrees.
Combine like terms.
3x + 93 = 180
Subtract 93 from both sides.
3x = 87
Divide both sides by 3

For their wedding, Ben and Jen paid $12 for each guest's dinner. The total bill was $2256. How many guests did they have at their wedding?
Answer:
188
Step-by-step explanation:
Very easy and simple division problem. All we need to do is divide the total number (2256) by the amount that they paid (12). This will give us how many people they payed for. The equation looks like this:
2256 ÷ 12 = 188.
If you need to prove this you can do 188 x 12 to find out for yourself. (It also equals 2256 proving the point.)
188 is your answer.
Hope this helps and have a nice day!

The number of bottles a machine fills is proportional to the number of minutes the machine operates. The
machine fills 250 bottles every 20 minutes. Create a graph that shows the number of bottles, y, the
machine fills in x minutes
А A
Answer:
The answer is below
Step-by-step explanation:
Let the number of bottles be y and the number of minutes the machine operate be x.
Given that number of bottles be is proportional to the number of minutes the machine operate, hence:
y is proportional to x.
⇒ y α x
y = kx, where k is a constant
when the number of bottles (y) = 250, the time the machine operates (x) = 20 minute. Therefore:
y = kx
250 = 20k
k = 250/20
k = 12.5
Hence the relationship between x and y is given as:
y = 12.5x
Plotting the function y = 12.5x using geogebra
