x = 12/22 = 0.545
Step-by-step explanation:
-2(-3x+7))=-2(1+8x)
Distrubute '-2's to brackets.
(6x-14)=(-16x-2)
Collet the 'x' in one place.
22x=12
Leave 'x' alone.
x=12/22
Rico bicycles at an average speed of 15.5 miles per hour. What distance will Rico bicycle in 180 minutes?
Answer:
46.5 miles
Step-by-step explanation:
Average speed × Time in hours = Distance
Average speed = 15.5 Miles per hour
Time = 180 minutes
We convert to hours
60 minutes = 1 hour
180 minutes = x
Cross Multiply
60x = 180
x = 180/60
x = 3 hours
Distance = 15.5 miles per hour × 3 hours
Distance = 46.5 miles
The distance Rico will ride his bicycle is 46.5 miles

Answer:
75 Degrees
Step-by-step explanation:
We know that all the angles of a triangle add up to 180.
We also know the each angle of triangle DEF in terms of variables
All we have to do is add the 3 angles which equal a total of 180 Degrees.
Angle D+E+F = 180 Degrees
(5+x) + (6+4x) + (4x) = 180
9x + 11 = 180
9x = 169
x = 18.8 Degrees
Angle F is 4x so it is 4(18.8) = 75 Degrees

A local college recently reported that enrollment increased to 108% percent of last year. If enrollment last year was at 20,000, about how many students enrolled this year? Round to the nearest whole number.
Answer:
the number of students enrolled this year is 21,600 students
Step-by-step explanation:
The computation of the number of students enrolled this year is as follows:
= Number of students enrolled last year × increased percentage
= 20,000 students × 108%
= 21,600 students
hence, the number of students enrolled this year is 21,600 students

Willow has 3/4 of a gallon of milk left that has an expiration date in 6 days. If she splits the milk equally among her next 6 bowls of cereal, how much milk will she use in each bowl
Answer:
[tex]\dfrac{1}{8}\ \text{gallons}[/tex]
Step-by-step explanation:
Amount of milk remaining is [tex]\dfrac{3}{4}\ \text{gallons}[/tex]
Number of bowls is [tex]6[/tex].
So, each bowl will contain
[tex]\dfrac{\dfrac{3}{4}}{6}[/tex]
[tex]=\dfrac{3}{4}\times \dfrac{1}{6}[/tex]
[tex]=\dfrac{3}{24}[/tex]
[tex]=\dfrac{1}{8}\ \text{gallons}[/tex]
Hence, each bowl will have [tex]\dfrac{1}{8}\ \text{gallons}[/tex] of milk.
Ahmed collects x kilograms of recycling. Kimaya collects 2/5 more than that. Write an equation that describes the relationship between the two quantities.
Answer: y=2/5x
Step-by-step explanation:
Y times x 2/5 which would be the answer
The equation that describes Ahmed collects x kilograms of recycling and Kimaya collects 2/5 more than that is {x + (2/5)x} kilograms.
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, Ahmed collects x kilograms of recycling and Kimaya collects 2/5 more than that.
∴ The equation that describes this scenario is,
= {x + (2/5)x}.
= (5x + 2)/5 kilograms.

In a game of luck, a turn consists of a player rolling 121212 fair 666-sided dice. Let X=X=X, equals the number of dice that land showing "111" in a turn. Find the mean and standard deviation of XXX.
Answer:
mean = 2
standard deviation = 1.3
Step-by-step explanation:
For a binomial random variable X, we can use this formula for mean:
meanX = np
We use this formula for the standard deviation:
sdX = sqrt(np(1 - p))
--------------------------------------------------------------------------------------------------
Since a turn consists of rolling 12 dice, we have n = 12.
The dice are fair and 6-sided, so the probability that each die lands showing "1" is p = 1/6.
meanX = np
= (12)(1/6)
= 2 dice
sdX = sqrt(np(1 - p))
= sqrt((12)(1/6)(5/6))
≈ sqrt(1.667)
≈ 1.291 dice
The mean and standard deviation of the game of luck are;
Mean = 2
Standard deviation = 1.29
We are told that a turn consists of rolling 12 fair six sided dice.
Thus;
n = 12
Probability of each one six sided die showing 1 is;
p = 1/6
Now,the formula for the mean is;
E(X) = np
Plugging in the relevant values gives;
E(X) = 12 × 1/6
E(X) = 2
Now, for the standard deviation, we will use the formula;
Standard deviation = √(np(1 - p))
Plugging in the relevant values;
Standard deviation = √((12 × 1/6)(1 - 1/6))
Standard deviation = 1.29
