The time to travel 190 miles will be 5 hour.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Charlotte drove 304 miles in 8 hours.
And, She continued at the same rate.
Now,
Since, Charlotte drove 304 miles in 8 hours.
Hence, The speed is,
Speed = Distance / time
= 304 / 8
= 38 miles / h
So, For travel 190 miles at same rate;
Time = Distance / Speed
= 190 / 38
= 5 hour
Thus, The time to travel 190 miles will be 5 hour.

1. Translate: A number divided into 4 2. Translate: The sum of 2/3 and a number 3. Translate: Drew is "n" years younger than Joe who is 9 years old
Answer:
1. x/4
2. 2/3+x
3. 9-n
Step-by-step explanation:
1. "A number" is an unknown value, so we set that as the variable. When a number is being divided, it's the divisor in a division problem (the first number)
2. The "sum" is the answer to an addition problem (like how the "quotient" is the answer to a division problem), which is why we know to add. Again, "a number" is the unknown value so we set that as the variable.
3. Because Drew is "n" years younger than Joe, Joe's age - n = Drew's age. The question tells us that Joe is 9 years old, so the expression would be 9-n.
I hope this helps! If it does, a brainliest would be much appreciated :)
. Una distribución de probabilidades permite organizar todos los resultados posibles de
una variable aleatoria junto con sus correspondientes probabilidades de ocurrencia.
El valor esperado E(x) de una variable aleatoria discreta se calcula multiplicando
cada valor que esta puede asumir por su probabilidad de ocurrencia y luego
sumando los productos.

What’s the second step of 2(x+1) =8x-5
Answer:
2(x + 1) = 8x - 5
assuming you already made the first step, the next step is to distribute the 2
2x + 2 = 8x - 5
if you havent made the first step, above is the first step.
the second step would be to combine like terms by subtracting 2x and adding 5 to both sides
7 = 6x
then you would divide both sides by 6
x = 7/6

The commission earned on the sale of a car can be reprsented by the equation C(p) = 250 + 0.02p, where c
represents the commission and P represents the purchase price of the car.
Jack sold two cars last weekend, one for $115,075 and the other for $21,640. Find his total commission.
Jack's commission=
Answer:
for first car
c = 250 + 0.02*$115,075 = 2551.5
for second car
c= 250 + 0.02*$21,640 = 682.8
total commission= 2551.5 +682.8 = 3234.3

Step-by-step explanation:
a rectangular hallway has dimension 6 feet by 18 feet. it is to be tiled with squares tiles, each with the dimension 2/3 feet by 2/3 feet. How many tiles will you need?
We need to find the area of the hallway. To find the area of a rectangle, simply multiply the length and width together.
6ft * 18ft = 108^ft
Now, let's find the area of the square tiles. To find the area of a square, simply square one side.
(2/3ft)^2 = 4/9ft^2
To find out how many square tiles are necessary to tile the hallway, lets divide the area of the hallway by the area of one square.
108ft^2 / (4/9ft^2) = 243 tiles

Which has a larger value: 4 x 10^2 or 7 x 10^4?
Answer:
7 x 10^4
Step-by-step explanation:
4 x 10^2 equals to 400, when 7 x 10^4 equals to 70,000
Answer:
[tex]7[/tex]× [tex]10^{4}[/tex]
Step-by-step explanation:
Because the exponent means that the number is being multiplied by itself that many times. Like [tex]10^{4}[/tex] means 10000 and that times 7 is 70000.
[tex]10^{2}[/tex] would be 100 and 100 times 4 is 400. Now to determine is 400 or 70000 larger? 70000 is larger.
Hope that helps and have a great day!
3(x - 1) - 8 = 4(1+x) + 5
Answer:
x= 20
Step-by-step explanation:
Step 1- Distribute into the parenthesis.
3x-1(3)-8= 1(4)+4x+5
Step 2- Multiply
3x-3-8= 4+4x+5
Step 3- Add.
3x-3-8= 4x+9
Step 4- Subtract 3x to both sides to move the variable to one side.
3x-11= 4x+9
-3x -3x
Step 5- Subtract 9 to both sides.
-11= 1x+9
-9 -9
-20= x
Exchange the signs.
20= x
Answer:
x = -20
Step-by-step explanation:
3(x - 1) - 8 = 4(1+x) + 5
3x - 3 -8 = 4 + 4x + 5
3x - 11 = 9 + 4x
-x = 20
x = -20

3(2x - 1) + 5 = 6(x + 1)
HELP!!!
Answer:
No Solution
Step-by-step explanation:
I have tried it a few times and there seems to be no solution. x can't be solved for.
Answer:
no solution
Step-by-step explanation:
Given
3(2x - 1) + 5 = 6(x + 1) ← distribute parenthesis on both sides
6x - 3 + 5 = 6x + 6 , that is
6x + 2 = 6x + 6 ( subtract 2 from both sides )
6x = 6x + 4 ( subtract 6x from both sides )
0 = 4 ← not possible
This indicates the equation has no solution
angie read 3 books in 5 days and each book contains 410 pages if angie reads if angie read the same number of books each day how may pages did she read a day
a.90
b.410
c.1,230
d.246
Answer:
D-246 pages.
Step-by-step explanation:
To find the total number of pages, you must do 3*410 which = 1,230. 1,230 is the total number of pages so then you divide that by 5 because there are 5 days so 1,230/5 = 246. So 246 pages per day.
ANSWER 246
410*3(books)=1230 /5(days) =246

How many integers satisfy the inequality (x 2 – 4)(x 2 – 10) < 0?
none
two
four
an infinite number
Answer:
4
Step-by-step explanation:
solution: −√10<x<−2 or 2<x<√10
√10=3.16
-3,-2,2,3
The 2 and -2 are the integers satisfy the inequality.
It is required to find the number of integers .
What is inequality?The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than’, or < ‘less than’.
Given:
For (x²– 4)< 0;
x²<4
By taking the square root of both sides we have,
√x²<√4
x < ±2
x<2 and x<-2
Also,
x²<10
By taking the square root of both sides we get,
√x²<±√10
x < ±√10
x<√10 and x<-√10
The √10 is not an integer but an irrational number. An integer is a whole number (not a fractional number) that can be positive, negative, or zero.
So we can't take the integer of ±√10.
Therefore, the 2 and -2 are the integers satisfy the inequality.
