Answer:
45 x + 55 x = 350
x increases until the total equals 350
45 + 55 = 100 = relative speed of approach
(B) traveling cars meet this equation's specifications (x = 3.5)
The correct statement is option B)
What is the speed of an object?Speed is the rate at which an object's position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time
Given here: The equation as 45x+55x=350
A car, traveling 45 mph, leaves Dallas heading for Odessa 350 miles away. At the same time, a truck leaves Odessa for Dallas traveling 55 mph on the same road.
Therefore the relative speed of the two trucks is given by 45+55=100
and let the time taken to meet is x then we can construct an equation as follows x=350/100
or, 45x+55x=350
Hence, The correct statement is option B)

Enter your answer as a mixed number in simplest form.
The mixed number is [tex]-14 \frac{4}{7}[/tex]
What are Mixed Numbers?
A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.
Given data ,
[tex]\frac{p}{1\frac{3}{7} } = -10.2[/tex]
To solve for p ,
Multiply by [tex]1\frac{3}{7}[/tex] on both sides we get ,
p = [tex]-10.2[/tex] × [tex]1\frac{3}{7}[/tex]
Now , [tex]1\frac{3}{7}[/tex] can be written as the improper fraction form as [tex]\frac{10}{7}[/tex]
So ,
p = [tex]-10.2[/tex] × [tex]\frac{10}{7}[/tex]
p = [tex]\frac{-102}{7}[/tex]
Now , the improper fraction [tex]\frac{-102}{7}[/tex] can be represented by the mixed number as [tex]-14 \frac{4}{7}[/tex]
Hence , The mixed number is [tex]-14 \frac{4}{7}[/tex]

Your friend, Susannah, manages a sandwich shop. She collects data on the number of turkey sandwiches sold per day for a week. Explain to her how to find the mean, median, mode, and range of the number of turkey sandwiches sold. How that would be helpful when she orders new turkey sandwich makings? Which measure do you think would be the most helpful for her and why?
Answer:
Step-by-step explanation:
Firstly for the the mean you add all the numbers and divide by how many they are.73+88+85+88+99+134+129 and divide it by 7 .
Secondly for the median arrange the numbers numerical form and pick the middle number.
Mode is finding the most common number.
Range subtract the largest number from the smallest number.the best measure is mean because it shows you all you bought and helps in finding the perfect amount

What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that 0.9 is the result of finding the product of 2 and 3/4 minus a number.
The unknown number will be calculated as,
( 2 x 3) / 4 - N = 0.9
N = (3 / 2) - ( 9/10)
N = ( 15 - 9 ) / 10
N = 6 / 10
N = 3 / 5
Therefore, the unknown number will be equal to 3 / 5. The correct option is C.

Which of the following numbers is between - 3/4 and 5/8 ?
Answer:
I believe that the answer is -1/2
Step-by-step explanation:
The number which falls under the inequality -3/4 < x < 5/8 is when x = -1/2
The correct answer is Option D.
Given data:
The number x is between -3/4 and 5/8.
So, the inequality is -3/4 < x < 5/8.
When comparing fractions, we consider their relative positions based on their magnitudes. Starting from the left, -3/4 represents a point closer to negative infinity, followed by -1/2, and then 5/8, which is closer to positive infinity.
Visually, imagine the number line where -3/4 is to the left, 5/8 is to the right, and -1/2 is positioned between them. Since -1/2 is greater than -3/4 and less than 5/8, it falls within the specified range. The choice -1/2 satisfies the condition and can be identified as the number between -3/4 and 5/8.
Hence, the number is x = -1/2.

With those already given, you need only plug them in to the formula:

Answer:
3: y = 3x - 5 4: y = 5/6x 5: -4x + 1
Step-by-step explanation:
I just use y = mx + b
x and y are the coordinates and m is the slope of the line (you could find the slope of a line by using rise over run or (y2 - y1) over (x2 - x1)) The y-intercept or b is the point where the line hits the y axis.

Sean and Evan are selling rolls of wrappign paper to raise money for new football uniforms. Evan has sold seven more than one-half the number of rolls that Sean has. If they have sold a total of 121 rolls, how many has Evan sold?
x - Rolls sold by Evan
Let x be the number of rolls sold by Sean.
We are given that Evan has sold 7 more that one-half the number of rolls that Sean sold.
Evan has sold 1/2x + 7 rolls.
Therefore, we have:
x + (0.5x + 7) = 121
1.5x = 121 - 7
x = 114/1.5
