Answers
Answer is a - b + c - d + e - f + g
Answer:
After Simplifying we get a - b + c - d + e - f + g
Step-by-step explanation:
We are given : a - { b - [ c - ( d - e ) - f ] - g }
We have to simplify it.
Step 1: First open the parenthesis mean ( ) brackets
we get , a - { b - [ c - d + e - f ] - g }
Step 2: Now we open Square brackets .i.e., [ ]
we get, a - { b - c + d - e + f - g }
Step 3: In last we open curly brackets .i.e, { }
we get, a - b + c - d + e - f + g
Therefore, After Simplifying we get a - b + c - d + e - f + g
Rewrite the following equation in slope-intercept form. 5x − 14y = 16 Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answers
The equation 5x − 14y = 16, when rewritten in slope-intercept form, is[tex]y = (5/14)x - 8/7.[/tex]
Explanation:To rewrite the given equation in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept, we'll isolate y. Starting with the equation 5x − 14y = 16:
1. Subtract 5x from both sides to move the x term to the other side:
-14y = -5x + 16
2. Divide every term by -14 to solve for y:
y = (5/14)x - 8/7
In this form, the coefficient of x represents the slope (m), which is 5/14, and the constant term is the y-intercept (b), which is -8/7. The slope indicates the rate of change of y concerning x, and the y-intercept represents the point where the line intersects the y-axis.
By following these steps, we've successfully transformed the given equation into slope-intercept form, making it easier to interpret and work within the context of linear relationships.
To convert the equation 5x - 14y = 16 to slope-intercept form, solve for y to yield y = (5/14)x - 8/7, where the slope is 5/14 and the y-intercept is -8/7.
Explanation:To rewrite the equation 5x − 14y = 16 in slope-intercept form, we need to solve for y to get the equation in the form of y = mx + b, where m is the slope and b is the y-intercept.
First, we subtract 5x from both sides of the equation:5x − 14y − 5x = 16 − 5xThis simplifies to −14y = −5x + 16.Next, we divide each term by −14 to solve for y:y = (−5x + 16) / −14Finally, we simplify the equation:y = (5/14)x − 16/14In simplified form, the slope-intercept form of the equation is y = (5/14)x − 8/7. Here, the slope (m) is 5/14 and the y-intercept (b) is −8/7.

A dot ran from -34 to -66. What distance did it cover? If this run took the dot 5 minutes, what was the average speed?
Answers
The dot's average speed was 384 units per hour
To find the distance the dot covered, we can subtract the initial position from the final position:
Distance = Final position - Initial position
[tex]\[ \text{Distance} = (-66) - (-34) \]\[ \text{Distance} = -66 + 34 \]\[ \text{Distance} = -32 \][/tex]
However, distance is a scalar quantity, so the negative sign indicates the direction. To find the magnitude of the distance, we take the absolute value:
[tex]\[ |\text{Distance}| = |-32| \][/tex]
[tex]\[ |\text{Distance}| = 32 \text{ units} \][/tex]
So, the dot covered a distance of 32 units.
To find the average speed, we use the formula:
[tex]\[ \text{Average speed} = \frac{\text{Distance}}{\text{Time}} \][/tex]
Given that the run took the dot 5 minutes, we need to convert the time to hours for the speed to be in units of distance per hour:
[tex]\[ \text{Time} = 5 \text{ minutes} = \frac{5}{60} \text{ hours} = \frac{1}{12} \text{ hours} \][/tex]
Now, plug the distance and time into the formula:
[tex]\[ \text{Average speed} = \frac{32 \text{ units}}{\frac{1}{12} \text{ hours}} \]\[ \text{Average speed} = 32 \times 12 \]\[ \text{Average speed} = 384 \text{ units/hour} \][/tex]
So, the dot's average speed was 384 units per hour.

Explanation:
1. The hypotenuse of the triangle is the larger side. Keeping this on mind, you must apply the Phytagorean Theoream, as below:ç
a²=b²+c²
"a" is the hyptenuse and "b" and "c" are the legs of the right triangle.
2. Then, you have:
a=13
b=12
c=5
3. If you apply the formula above to calculate the hypotenuse and the result is 13, then those are the lengths of sides of the right triangle. Therefore:
a²=b²+c²
a=√b²+c²
a=√(12)²+(5)²
a=√144+25
a=13

The four integers you're looking for are
-4

-7
This is because they add up to -4 + -5 + -6 + -7 = - 4 - 5 - 6 - 7 = - 22
x+1= 2nd integer
x+2= 3rd integer
x+3= 4th integer
Add the above integers and set equal to -22.
x + (x+1) + (x+2) + (x+3)= -22
combine like terms
4x + 6= -22
subtract 6 from both sides
4x= -28

Explanation:
The term "perpendicular" implies that the angle formed between the two lines is 90 degrees.
These two lines do not have to be equal in length, they just intersect forming a 90-degree angle.
Comparing the explanation with the given choices, we would find that the only correct choice is:

Jennifer is planning a holiday. The hotel costs $60 per night and her flights cost $150. She has a budget of £500 for hotel and flights. Up to how many nights can she afford in the hotel?
Answers
Answer:
5 nights
Step-by-step explanation:
Let x represent the number of nights. She can spend up to and including 500; this gives us the inequality
60x+150 ≤ 500
Subtract 150 from each side:
60x+150-150 ≤ 500-150
60x ≤ 350
Divide both sides by 60:
60x/60 ≤ 350/60
x ≤ 5.83
Since she cannot stay just a portion of a night, she can stay up to 5 nights.
Jennifer can afford to stay in the hotel for up to 10 nights.
Explanation:To determine the number of nights Jennifer can afford in the hotel, we need to subtract the cost of the flights from her budget and divide the remaining amount by the cost per night.
First, convert Jennifer's budget from pounds to dollars. Assuming an exchange rate of 1 pound = 1.5 dollars, £500 is equal to $750.
Next, subtract the cost of the flights from Jennifer's budget to find her remaining budget for the hotel. $750 - $150 = $600
Finally, divide the remaining budget by the cost per night to find the number of nights she can afford. $600 / $60 = 10 nights.
Therefore, Jennifer can afford to stay in the hotel for up to 10 nights.

Ms.Gartland bought x number of shirts for the new members of her chorus.The cost for x number of shirts,including $3.99 shipping,was $ 77.49.Each shirt cost $12.25.There was no sales tax on this purchase.Which equation could be used to find x?
A 3.99(x+12.25)=77.49
B 3.99x+12.25=77.49
C 12.25(x+3.99)=77.49
D12.25x+3.99=77.49
Answers
She bought 'x' number of shirts.
The price of one shirt = 12.25 dollars.
Then total price of all shirts would be '12.25x' dollars.
Given is the shipping charge = 3.99 dollars.
Given is the total bill = 77.49 dollars.
It says no other tax would be charged on this order, so total bill would be sum of total price of all shirts and shipping charges.
Total Bill = Total price of all shirts + Shipping charges.
77.49 = 12.25x + 3.99
Hence, option D is correct i.e. 12.25x + 3.99 = 77.49

To solve this question we will have to make use of the triangle inequality which states that "the sum of the lengths of any two sides of a triangle must be greater than the length of the third side".
Let us now use this inequality to check Part A to Part E.
Part A: [tex] 3+4\ngtr9 [/tex] therefore, triangle is not possible
Part B: [tex] 3+6\ngtr9 [/tex] therefore, triangle is not possible
Part C: [tex] 4+5\ngtr9 [/tex] therefore, triangle is not possible
Part D: [tex] 4+6>9, 4+9>6, 6+9>4 [/tex] As all the three sides adhere to the triangle inequality, a triangle is possible with these dimensions.
Part E: [tex] 5+5>9, 5+9>5, 9+5>5 [/tex] As all the three sides adhere to the triangle inequality, a triangle is possible with these dimensions.
Thus, only Options D and E apply

What number is a common denominator for 3/8and1/3

24 is the LCD for 3/8 and 1/3.
The least common multiple is 24, so the LCD is 24, too. A "Common Denominator" is a number that can be divided by all the denominators in a group of fractions.
24 is a common denominator for this example:
3/8(3/3) = 9/24
1/3(8/8) = 8/24
9/24 and 8/24 have common denominators, while their numerators are also multiplied, for 'what you do to the bottom, you do to the top' (sorry forgot the exact term for it)
