The value of Expression 1/3 x (15+6) on simplification gives 7.
To simplify the expression 1/3 x (15+6),
we start by simplifying the addition inside the parentheses.
=15 + 6
= 21
Now, we can multiply the result by 1/3:
= 1/3 x 21
= 21/3
= 7
Therefore, 1/3 x (15+6) simplifies to 7.

M is the midpoint of segment VW. Find the value of n.
Answer
x=4
Step-by-step explanation:
4x-1=3x+3 because both sides are equal, since M is a midpoint.
Subtract 3x to both sides to get x-1=3.
Add 1 to both sides to get x=4.
Answer:
[tex]\huge\boxed{\sf x = 4}[/tex]
Step-by-step explanation:
If M is the midpoint of VW.
Then,
WM = MW
Given that WM = 4x - 1 and MW = 3x + 3
So,
4x - 1 = 3x + 3
Combining like terms
4x - 3x = 3 + 1
x = 4

A withdrawal is taking money out which is a negative value.
She took $18 out so it would be written as -18.
The answer is:
A number line going from negative 20 to positive 20. A point is at negative 18.
Answer:
Carly withdraws $18 from her bank account.
We assume that Carly has $x in her account. She withdraws $18 from her bank account.
So we have to subtract $18 from $x amount.
Which is $x - 18.
So we are subtracting $18 from her account.
It should be represented by an integer -18.
Now we have to identify the which number line represents -18.

Step-by-step explanation:

The mean increased, but the median remained constant If new dogs' weights are added to the data set.
What is the mean of a data set?The mean of a data set is defined as the ratio of the sum of observations to the total number of observations. It can be referred to as the average of a specific set of data or the arithmetic mean.
The formula for the mean of a given set of data is as follows:
Mean = Sum of Observations/Total number of observations
Given the set of observations as :
16, 34, 44, 20, 50, 19, 30, 54
Arrange the data in ascending order, we get
16, 19, 20, 30, 34, 44, 50, 54
The median of the given data would be (30+34)/2 = 32.
Here, n = 8
⇒ ∑x = Sum of Observations
⇒ ∑x = 267
Mean = ∑x/n
Mean = 267/8
Mean = 33.375
If two more dogs weighing 25 pounds and 45 pounds come to the kennel.
Arrange the given data in ascending order, we get
16, 19, 20, 25, 30, 34, 44, 45, 50, 54
The new median of the data would be (30+34)/2 = 32.
New mean = 337/10 = 33.7
Therefore, the mean increased, but the median remained constant If new dogs' weights are added to the data set.

3.456x(2.05x10^5) = ?
Answer:
708480
Step-by-step explanation:
You follow the order of BEDMAS. There are brackets in this equation, meaning we have to focus on what is inside the brackets first. The next step is Exponents. So you multiply 2.05 by 10^5.
This would give you 205000.
You then multiply this number by the number on the outside of the brackets which is 3.456.
This would give you 708480. (You can get these answers by using a calculator).
Don't forgot to follow the order of BEDMAS or whatever law of operations you were taught (BIDMAS/BIMDAS etc)

Chloe drives from her house to her grandma's house 64 miles away in an hour and 35 minutes. How fast was she driving on average? About 47 mph About 53 mph About 40 mph About 30 mph
Answer:
She was driving at 40.42 mph on averageStep-by-step explanation:
In this exercise, for us to find the speed that Chloe drives with we need to first convert the time she spent driving to hours completely since the time given is in hours and minute
Data
distance= 64 mile
time= 1hr 35min
to covert 1 hr 35 min to hours we have
= 1 + 35/60 (we are converting 35 min to hrs)
= 1+0.583
= 1.583
hence speed= 64/ 1.583
speed= 40.42 mph
She was driving at 40.42 mph on average
About 40 miles per hour

Answer:
[tex]y=8[/tex]
[tex]RS=77, ST=31[/tex]
Step-by-step explanation:
Note that the entire segment RT is the combined lengths of RS and ST. So:
[tex]RT=RS+ST[/tex]
We know that RT is 108, RS is (9y+5), and ST is (3y+7). Substitute:
[tex]108=(9y+5)+(3y+7)[/tex]
On the right, combine like terms:
[tex]108=(9y+3y)+(5+7)[/tex]
Add:
[tex]108=12y+12[/tex]
Subtract 12 from both sides. The right cancels:
[tex]96=12y[/tex]
Divide both sides by 12:
[tex]y=8[/tex]
So, the value of y is 8.
To find RS and ST, substitute 8 for y. So:
[tex]RS=9y+5[/tex]
Substitute 8 for y:
[tex]RS=9(8)+5[/tex]
Multiply:
[tex]RS=72+5[/tex]
Add:
[tex]RS=77[/tex]
Do the same for ST:
[tex]ST=3y+7[/tex]
Substitute 8 for y:
[tex]ST=3(8)+7[/tex]
Multiply:
[tex]ST=24+7[/tex]
Add:
[tex]ST=31[/tex]

Sam is flying from Columbus, Ohio, to Kralendijk, Bonaire, a distance of 2,488 miles. First, he flies 995 miles to Miami, Florida. He then flies from Miami to San Juan, Puerto Rico, a distance of 1,033 miles. How many miles will he travel flying from Columbus to San Juan? How many more miles does he have to fly to Kralendijk? Enter your answers in the boxes. From Columbus to San Juan, Sam flies miles. He will have more miles to fly.
Answer:
1) From Columbus to San Juan, Sam flies 2,028 miles
2)Sam will have 460 miles more miles to fly to Kralendijk
Step-by-step explanation:
The given information are;
The total (flight) distance from Columbus, Ohio to Kralendijk, Bonaire = 2,488 miles
The distance Sam flies from Columbus to Miami, Florida = 995 miles
The distance Sam flies from Miami to San Juan = 1,033 miles
1) Therefore, the number of miles Sam travels flying from Columbus to San Juan is given as follows;
The number of miles Sam will have to travel flying from Columbus to San Juan = (The distance Sam flies from Columbus to Miami, Florida) + (The distance Sam flies from Miami to San Juan)
The number of miles Sam will have to travel flying from Columbus to San Juan = 995 miles + 1,033 miles = 2028 miles
The number of miles Sam will have to travel flying from Columbus to San Juan = 2,028 miles
Therefore, from Columbus to San Juan, Sam flies 2,028 miles
2) The number of more miles Sam has to fly to Kralendijk from Sam Juan is therefore;
The number of more miles Sam has to fly to Kralendijk from Sam Juan = (The total (flight) distance from Columbus, Ohio to Kralendijk, Bonaire) - (The number of miles Sam will have to travel flying from Columbus to San Juan)
The number of more miles Sam has to fly to Kralendijk from Sam Juan = 2,488 miles - 2,028 miles = 460 miles.
The number of more miles Sam has to fly to Kralendijk from Sam Juan = 460 miles.
Therefore, Sam will have 460 miles more miles to fly to Kralendijk
From the division of the trip into parts, it is found that:
From Columbus to San Juan, Sam flies 2028 miles.He will have more 460 miles to fly.--------------------
The total distance of Columbus -> Kralendijk is 2488 miles.The first part, Columbus -> Miami, is 995 miles.The second part, Miami -> San Juan, is 1033 miles.The final part, San Juan -> Kralendijk, is x miles.--------------------
Since Columbus to Miami is 995 miles and Miami to San Juan is 1033 miles, we have that the distance from Columbus to San Juan, in miles, is of:
[tex]995 + 1033 = 2028[/tex]
Thus:
From Columbus to San Juan, Sam flies 2028 miles.
--------------------
The total distance is 2488 miles.Until San Juan, it is 2028 miles. The final part is San Juan to Kralendijk, x miles, thus:[tex]2028 + x = 2488[/tex]
[tex]x = 2488 - 2028[/tex]
[tex]x = 460[/tex]
Thus:
He will have more 460 miles to fly.
