Answer:
-3(4c-2) -2c = -14c+6
Step-by-step explanation:
We need to find the equivalent expression for -3(4c-2) -2c.
First we open the brackets as follows :
-3(4c-2) -2c
= -12c+6-2c
=-12c-2c+6
=-14c+6
So, the equivalent expression is -14c+6.

Michonne's Phone Service charges $11.06 for an activation fee plus $4 for every gigabyte (g) used.
Answer:
Graph the line of y=11.06x+4
Step-by-step explanation:
First write the equation of the line you want to graph. In this case the values are 11.06 as m, and 4 as the y-intercept (b). If you substitute the values into y=mx+b. Then you need to graph it. Plot the y-intercept, then use rise/run to complete the rest of the points and the line.

Instead of using the values {1,2,3,4,5,6}
on dice, suppose a pair of dice have the
following: {1,2,2,3,3,4} on one die and
{1,3,4,5,6,8} on the other. Find the
probability of rolling a sum of 7 with
these dice. Be sure to reduce.
?
]
Answer:
[tex]Probability(sum7)=\frac{4}{24}=\frac{1}{6}[/tex]
Step-by-step explanation:
The dice form pairs of outcomes, so if the dice has repeating sides then the set of outcomes will be pairs of elements from the set {1,2,3,4} and {1,3,4,5,6,8}. The number of possible two pair combinations is 4 times 6 which equals 24 possible pairs. Now we find which of these pairs would have values summing up to 7: [tex](1,6),(2,5),(3,4),(4,3)[/tex] So 4 outcomes out of a possible 24 outcomes have this qualityThat's [tex]Probability(sum7)=\frac{4}{24}=\frac{1}{6}[/tex]Answer:

The manager of the zoo where the ticket price for an adult is $9.50 and the ticket price for a child is $6.50 wants to make at least $800 on a Saturday. Let x be the number of adult tickets and y be the number of child tickets. Choose the inequality that shows the numbers of tickets that need to be sold.
Answer:
[tex]9.5x+6.5y\geq $800[/tex]
Step-by-step explanation:
9.5 in value of adult tickets. 6.5 is value of children's tickets. combined selling of all of them should be greater than or equal to 800 ("atleast" in the question shows it can be more but cannot be less)
martin reads 19 pages of a novel in 12 minutes. complete the proportion and use it to find x, the number of pages he reads in 42 minutes
Answer:
67 pages in 42 minutes
Step-by-step explanation:
Consider the integers x and y. When y is divided by x the remainder is 29. When y is divided by x/2, the remainder is 13. Determine x.
===============================================
Explanation:
When we divide y over x to get a remainder of 29, this means we are dividing over a value greater than 29. This means x > 29.
If we divided over a number 29 or less, then the remainder would be smaller than the divisor.
------------------------------------------
The variable x is some integer. When we divide y over (x/2) we get some other integer. This implies that x/2 itself is also an integer. That tells us that x is some even integer.
So far we know that x > 29 and x is some even number.
------------------------------------------
y divided by x leads to a remainder of 29. This means
y/x = q + 29/x
for some integer q, which is the quotient.
Multiply both sides by x
x*(y/x) = x*(q + 29/x)
y = qx + 29
We'll come back to this later.
------------------------------------------
Now divide y over (x/2) to get a remainder 13. We'll let n be the quotient this time
y/(x/2) = n + 13/(x/2)
which is equivalent to
y = n(x/2) + 13
We can multiply both sides by 2 further getting
2y = 2*( n(x/2) + 13 )
2y = nx + 26
Plug in y = qx+29 from earlier
2(qx+29) = nx + 26
2qx + 58 = nx + 26
Let's group the x terms to one side and everything else on the other side
2qx - nx = 26-58
2qx - nx = -32
-nx + 2qx = -32
nx - 2qx = 32
I multiplied both sides by -1 to turn that -32 into 32
Factoring x from the left side gives
nx - 2qx = 32
x(n - 2q) = 32
We have x as an integer, which is stated in the instructions.
In order to have x(n-2q) = 32 be true, this must mean n-2q is an integer.
We can say n-2q = 32/x, so 32/x is some integer because x is an integer.
------------------------------------------
In short, x and n-2q are both integers. In order for the two integers to multiply to 32, the factors must be smaller than 32 or equal to 32.
So [tex]x \le 32[/tex] and [tex]n-2q \le 32[/tex]
We don't need to worry about the second inequality since all we care about is x.
Recall that earlier we stated that x > 29 and x is even.
Combine this with [tex]x \le 32[/tex] and we form the compound inequality [tex]29 < x \le 32[/tex]
This basically says x is a value from the set {30, 32}
But x = 30 is not a factor of 32. There's no way to have x(n-2q) = 32 be a true equation if x = 30. We must rule x = 30 out.
The only thing left is x = 32. This is the final answer.
------------------------------------------
If x = 32 and y = 29, then we fit the requirements of the problem.
y/x = 29/32 = 0 remainder 29
y/(x/2) = 29/16 = 1 remainder 13
The solution has been confirmed.

The highest mountain in the world is Mt. Everest, whose peak is 29,029 feet above sea level. But the tallest mountain is Mauna Kea. The base of Mauna Kea is 19,669 feet below sea level, and its peak is 33,465 feet above its base. How much higher above sea level is Mt. Everest than Mauna Kea?
42825 or 9360
Step-by-step explanation:
So we know that Mt. Everest has a peak that is 29,029 feet above sea level.
To find how much Mauna Kea is above sea level then we would subtract the feet below sea level (19,669ft) from the overall height of the mountain (33,465ft). Like this:
33,465ft - 19669ft = 13,796 feet
Now that we know both mountains height above sea level, we can answer the question.
We will take Everest's height above sea level and subtract Mauna's height above sea level. Like this:
29,029ft - 13,796ft = 15,233
Therefore, Mt. Everest is 15,233 feet taller above sea level than Mauna Kea.
Hope this helps!

Move AC and BD so that their midpoints coincide. Then draw a polygon through A, B, C, and D to form quadrilateral ABCD. Measure and record the slope of each slide of quadrilateral ABCD
Answer:
look attachment below
Step-by-step explanation:
We find the midpoints of AC and BD and the corresponding coordinates for quadrilateral ABCD.
Midpoint of AC: ( (x₁ + x₃) / 2 , (y₁ + y₃) / 2 )
Midpoint of BD: ( (x₂ + x₄) / 2 , (y₂ + y₄) / 2 )
Then we can measure and record the slopes of each side.
Slope = (y₂ - y₁) / (x₂ - x₁)
Here,
To draw quadrilateral ABCD with the midpoints of AC and BD coinciding, we first need to find the midpoints of AC and BD.
The midpoint of a line segment is the average of the coordinates of its endpoints.
Given points A(x₁, y₁), B(x₂, y₂), C(x₃, y₃), and D(x₄, y₄), we can find the midpoints as follows:
Midpoint of AC: ( (x₁ + x₃) / 2 , (y₁ + y₃) / 2 )
Midpoint of BD: ( (x₂ + x₄) / 2 , (y₂ + y₄) / 2 )
Once we have the coordinates of the midpoints, we can connect them to form quadrilateral ABCD.
To measure the slope of each side of quadrilateral ABCD, we need to find the slope of each line segment formed by connecting points A, B, B, C, C, D, and D, A.
The slope of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by:
Slope = (y₂ - y₁) / (x₂ - x₁)
Let's assume we find the midpoints of AC and BD and the corresponding coordinates for quadrilateral ABCD. Then we can measure and record the slopes of each side.

Carry your intermediate computations to at least four decimal places, and round your answer to at least two decimal places
Answer:
P(X > 4) = 0.93
Step-by-step explanation:
This is a binomial probability distribution problem with the formula;
P(X = x) = C(n, x) × p^(x) × (1 - p)^(n - x)
We are told that a new surgery is successful 85% of the time. Thus;
p = 85% = 0.85
n = 7
probability that more than 4 of them are successful would be;
P(X > 4) = P(5) + P(6) + P(7)
P(5) = C(7,5) × 0.85^(5) × (1 - 0.85)^(7 - 5)
P(5) = 0.2097
P(6) = C(7,6) × 0.85^(6) × (1 - 0.85)^(7 - 6)
P(6) = 0.3960
P(7) = C(7,7) × 0.85^(7) × (1 - 0.85)^(7 - 7)
P(5) = 0.3206
P(X > 4) = 0.2097 + 0.3960 + 0.3206
P(X > 4) = 0.9263 ≈ 0.93
