Patty says that if you add the same negative integer five times, the sign of the sum is negative and its size is five times the size of the original integer.
For example:
(-7) + (-7) + (-7) + (-7) + (-7)
= 5 x (-7)
= - 35
Is Patty’s statement true for all integers?
The price of an item has risen to $207 today. Yesterday it was $180. Find the percentage increase
Answer:
15% '
Step-by-step explanation:
Price yesterday = $180
Price today = $207
Increase in price = $(207 - 180)
=> $27
Percent increase =
Increase / Price of yesterday
=> 27 / 180 * 100
=> 3 / 2 * 10
=> 30 / 2
=> 15
15%
Therefore, the rise in the price of the item = 15%

The width of a rectangle is two-thirds of the length. The perimeter of the rectangle is 15 centimeters. What is the length, l, of the rectangle? Explain.
Answer:
The legth of I is 15.
Step-by-step explanation:
hope this helps :))
The length of the rectangle is given by the equation L = 4.5 cm
What is the Perimeter of a Rectangle?The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.
Perimeter P of rectangle = 2 ( Length + Width )
Given data ,
Let the perimeter of the rectangle be represented as P = 15 cm
Now , the equation will be
Let the length of the rectangle be L
Let the width of the rectangle be W
Now , width of a rectangle is two-thirds of the length
Substituting the values in the equation , we get
W = ( 2/3 ) L
And , Perimeter P of rectangle = 2 ( Length + Width )
Substituting the values in the equation , we get
15 = 2 ( L + ( 2/3 ) L )
On simplifying the equation , we get
15/2 = L + ( 2/3 )L
15/2 = 5L/3
15 = 10L/3
Multiply by 3 on both sides of the equation , we get
45 = 10L
Divide by 10 on both sides of the equation , we get
L = 4.5 cm
Therefore , the value of L is 4.5 cm
Hence , the length of the rectangle is 4.5 cm

A middle school took all of its 6th grade students on a field trip to see a play at a theater that has 2760 seats. The students filled 45% of the seats in the theater. How many 6th graders went on the trip?
Answer:
1242 6th graders went on the trip.
Step-by-step explanation:
From the information given, you know that the theater has 2760 seats and that the students filled 45% of the seats, so to find the quantity of 6th graders that went on the trip, you have to calculate 45% of 2760:
2760*45%=1242
According to this, the answer is that 1242 6th graders went on the trip.
The temperature in degrees Celsius can be determined using the expression 5 9 (F – 32) where F is the temperature in degrees Fahrenheit (°F). Use the given expression to determine the temperature in degrees Celsius when F = 86°
Answer:
The temperature on Celsius scale for 86 ºF is 30 ºC.
Step-by-step explanation:
Both degrees Celsius and Fahrenheit are relative scales of temperature. The relationship between degrees Fahrenheit and degrees Celsius is summarized by the equation below:
[tex]T_{C} = \frac{5}{9}\cdot (T_{F}-32)[/tex] (1)
Where:
[tex]T_{F}[/tex] - Temperature, measured in degrees Fahrenheit.
[tex]T_{C}[/tex] - Temperature, measured in degrees Celsius.
If we know that [tex]T_{F} = 86\,^{\circ}F[/tex], then its equivalent temperature on Celsius scale is:
[tex]T_{C} = \frac{5}{9}\cdot (86-32)[/tex]
[tex]T_{C} = 30\,^{\circ}C[/tex]
The temperature on Celsius scale for 86 ºF is 30 ºC.

Step-by-step explanation:
Slope-intercept form:
[tex]y=mx+b[/tex]
where:
m is the slopeb is the y-interceptx and y are corresponding coordinate pointsWhen two lines are parallel, their slopes are the same. Mak a new equation with the same slope:
[tex]y=\frac{1}{2} x+b[/tex]
Now we need to find the value of b. Insert the given point for x and y:
[tex]-4=\frac{1}{2} (2)+b[/tex]
Solve for b.
Simplify multiplication. Follow the rule [tex]\frac{a}{b} *c=\frac{ac}{b}[/tex]:
[tex]-4=\frac{1*2}{2} +b\\\\-4=1+b[/tex]
Isolate the variable. Subtract 1 from both sides:
[tex]-4-1=1-1+b\\\\-5=b[/tex]
The y-intercept is -5. Insert, replacing the "+":
[tex]y=\frac{1}{2} x-5[/tex]

Andrea does not understand why if x is a solution to the equation 3-x=4 then x is also a solution to the equation 12=9-3x. Write a convincing explanation as to why this is true
Answer:
Both equations are same
Step-by-step explanation:
The reason why this is true is not far fetched
looking at the first equation, we have;
3-x = 4
we can also factorize the second equation to look this way
By this, we shall be having
3(4) = 3(3-x)
By the time we take out the 3 from both sides, we will have the initial equation
So what we are saying is that both equations are the same

There are 40 dimes and quarters in a drawer. The total amount of the coins
are $4.75. How many quarters are there?
A. 35
B. 5
C. 19
Answer:
There should be 3 quarters
Step-by-step explanation:
here's why....40 dimes is 4.00 plus 3 quarters is 4.75
The required number of quarters is given as 5, as of the given conditions.
Given that,
There are 40 dimes and quarters in a drawer. The total amount of the coins is $4.75.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
let the number of dimes be d and the number of quarters be q,
According to the question,
d + q = 40 - - - - - (1)
0.10d + 0.25q = 4.75 - - - - - (2)
From equation 1 substitute x in equation 2
0.10[40 - q] + 0.25q = 4.75
4 - 0.10q + 0.25q = 4.75
0.15q = 0.75
q = 5
Out q in the equaiton 1,
d + 5 = 40
d = 35
Thus, the required number of quarters is given as 5, as of the given conditions.
