Answer: No. Colin was incorrect.
Step-by-step explanation:
From the question, we are informed that the answer that Colin had on his paper was −1/3 − (1/5 + 5/8) while the correct answer, located in the back of the book, was −1/3 −1/5 + 5/8.
Colin was wrong because he didn't take into effect that the minus has affected the figures in the bracket. Therefore, 1/3 − (1/5 + 5/8) simply means 1/3 - 1/5 - 5/8.
He didn't realise that (-) × (-) = + which has resulted in the change of the sign beside 5/8 from positive to negative.

How can you solve one-step multiplication and division equations?
Answer:
Step-by-step explanation:
All of these equations only require a single operation before you get x alone. for example: x - 2 = 6 Compared with 2x = 6
For the first one, you have to add two and get x = 8. for the second one, Then you divide by 2 and get x = 3. they're both a single step, as the name "one-step" equations tells you, and you only have to divide, multiply, add, or subtract one value.

The question is an illustration of fraction division.
8 visitors shared the pizza
Given
[tex]Pizza = 2[/tex]
[tex]k = \frac 14[/tex] --- the amount each visitor was given
The number of visitors (n) is calculated using:
[tex]n =\frac{Pizza}{k}[/tex]
So, we have:

Critique the the reasoning of others. Connor determines the slope between (-2,4) and (3,-3) by calculating 4 -(-3)/ -2 - 3. April determines the slope by calculating 3 - (-2) / -3 - 4. Explain whose reasoning is correct.
Answer:
Connor's
Step-by-step explanation:
According to the slope formula, it is (y2 - y1)/(x2 - x1)
Connor uses the y-values first and put them on the numerator, and that is what you are meant to do, unlike, April. She puts the x-values on top and the y-values on the bottom.

The Spanish club held a car wash to raise money why equals Y=5X represents the amount of money The Y club members made Washing cars identify the constant Proportionality
Given:
The amount of money y club members made for washing x cars is
[tex]y=5x[/tex]
To find:
The constant Proportionality.
Solution:
If y is directly proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
where, k is constant of proportionality.
The amount of money y club members made is proportional to number of cars washing x.
We have,
[tex]y=5x[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]k=5[/tex]
Therefore, the constant proportionality is 5.

An open top box is made from a rectangular piece of cardboard, whose length is twice the width, by cutting a 3 in square from each corner and folding up the remaining sides. The area of the bottom of the box is 140 inches squared. What is the width?
Answer:
Width = 13 inch
Step-by-step explanation:
Assume;
Width = x
Length = 2(width) = 2x
Cut 3 inch from each corner:
Width = x-3-3 = x - 6
Length = = 2x-3-3 = 2x - 6
Area of rectangle = lb
Area of rectangle = [length][width]
Area of rectangle = (2x - 6)(x - 6)
Area of rectangle = (2x - 6)(x - 6)
140 = 2x² - 12x - 6x + 36
2x² - 18x - 104
x² - 9x - 52
x² - (13-4)x - 52
x² - 13x + 4x -52
x(x-13)+4(x-13)
(x-13)(x+4)
So,
x = 13 or x = 4
Width = 13 inch

Use the provided ruler to measure the segment shown. Find the scale of the drawing. The length of the segment is ___ centimeters. The scale is ___ cm : ___ m.
Answer:
Length of boat = 12,000cm
Scale: 100cm : 1m
Step-by-step explanation:
Find the diagram attached
Given
Length of the boat = 120m
Using the conversion
100cm = 1m
Converting to 120m to centimeters
x cm = 120m
100cm = 1m
Cross multiply
x×1 = 120×100
x = 12,000cm
.
Hence the length of the measured segment is 12,000cm
The scale used will be according to the conversion rate used
The scale used will be 100cm : 1m
Answer:
The actual answer is:
Length if the segment is 4 centimeters.
the scale is 1 cm : 30 m

Which of the following triangles below make a right triangle?
Answer:
b
Step-by-step explanation:
Suppose that you decide to buy a car for $57,000, including taxes and license fees. You saved $10,000 for a down payment. The dealer is offering you a choice between two incentives. Incentive A is $5000 off the price of the car, followed by a four-year loan at 6.06%. Incentive B does not have a cash rebate, but provides free financing (no interest) over four years. What is the difference in monthly payments between the two offers? Which incentive is the better deal? Use PMT= P r n 1−1+ r n−nt. The difference in monthly payments between the two offers is $nothing. (Round to the nearest cent as needed.)
Answer:
Following are the solution to this question:
Step-by-step explanation:
For incentive A
The car value = 57000
Calculating debt[tex]= 57000 - 10000[/tex]
[tex]= 47000[/tex]
Calculating the debt value after incentive [tex]= 47000 - 5000[/tex]
[tex]= 42000[/tex]
[tex]PMT = \frac{P(\frac{r}{n})}{(1 - (1 + (\frac{r}{n}))^(-nt))}[/tex]
[tex]= \frac{42000 \times (\frac{6.06 \%}{12})}{(1-(1+(\frac{6.06 \%}{12}))^{(-12 \times 4)})}[/tex]
[tex]= \frac{42000 \times (0.00505)}{(1-(1+(0.00505))^{(-48)})}\\\\= \frac{212.1}{(1-(1+(0.00505))^{(-48)})}\\\\=\frac{212.1}{-1.74}\\\\= - 121.89 \ \ or \ \ 121.89[/tex]
For incentive B
The car value = 57000
Calculating the debt value [tex]= 57000 - 10000[/tex]
[tex]= 47000[/tex]
Calculating the monthly payment =[tex]\frac{47000}{(12*4)}[/tex]
[tex]= \frac{47000}{(48)}\\\\= \frac{47000}{(48)}\\\\=979.166[/tex]
difference:
[tex]=121.89 - 979.166\\\\ = - 854.276[/tex]

/6 /6
3/6= 1/2 (simplify)
x=1/2
8(x - 2) - 4 = 28
What does x equal
Answer:
6
Step-by-step explanation:
first, we multiply the 8(x - 2)
8 times x = 8x
8 times - 2 = -16
8x - 16 - 4 = 28
-16 - 4 = -20
8x -20 = 28
add 20 to both sides
48
8x = 48
