If Allies parents are willing to spend $300 for her party, how many people can attend? Show your work.
Answer:
17
Step-by-step explanation:
Since C represents the cost, and Allie's parents are willing to spend $300 for the party, our equation will now look like this:
300=5p+215
we are trying to find out how many people will able to attend
300=5p+215
-215 -215
---------------------
85 = 5p
divide by 5 on both sides to undo the multiplication (5p)
300=5p+215
-215 -215
---------------------
85 = 5p
÷5 = ÷5
--------------
17 = p
So, p (number of people attending) would be 17 :)

How much does Sam need to save?Sam needs to save three times his expenses:
= 1,712 x 3
= $5,136
How long will it take Sam to save this amount?= Amount to be saved / Amount saved monthly
= 5,136 / 210
= 24 months approximately.
________________________________________________________
The question is:
Using his essential expenses as a guideline, how much will Sammy need to save if he wants to have 3 times the amount of his living expenses in the bank as part of his emergency savings. How long will it take him to achieve his goal?
a. $1,712; approximately 8 months

Answer:
1) Measure angle QWT and TWX are complementary because their measures add up to 90 degrees.
2) Both measure angles add up to 90 degrees because they're complementary.
3) Angle QWT = 2x and angle TWX = x + 6, and since angles QWT + TWX = 90 then 2x + x + 6 = 90.
4) (Made up?:) Angle measure QWX = 90. The quarter-turn, or the small square, indicates that the angle is 90 degrees.
5) (?)
6) x = 28 because it fulfills the equation, 2x + x + 6 = 90, or 3x + 6 = 90. 90 - 6 is 84, and 84/3 is 28.

What is Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number be x
The number when decreased by 9 , the result is 24
So , x - 9 = 24
Adding 9 on both sides , we get
x = 33
Hence , the number is 33

-2x – 6y = -24
X-8y = -10
Answer:
{x,y}={31,4}
Step-by-step explanation:
x-8y = -1 x-6y = 7
Answer:
first we find the value of 'y' so
x-8y=-10+8y
x=-10+8y
-2(-10+8y)-6y=-24
20-16y-6y=-24

The value of ∠BAD would be as follows:
D). 63
Find the angleGiven that,
The measure of ∠ABC [tex]= 114[/tex]
We know that,
BD bisects the ║gm ABCD

∠ABD [tex]= 57[/tex]
Since opposite angles of a ║gm give equal
∠ABC = ∠ADC
So,
∠ ADB [tex]= 57[/tex]
Since the sum of all the angles of a ║gm is 360.
∠BAD can be found using this.

Bridgette has $1,000 to invest. She has two different investment options, shown in the table below. Each option would give her a different value over three years.
Number of Years 1 2 3
Option A (amount in dollars) 1100 1200 1300
Option B (amount in dollars) 1100 1210 1331
Part A: What type of function, linear or exponential, would be best to describe the value of the investment over a fixed number of years using Option A? Explain your answer.
Part B: Write a function, a(t), to describe the value of the investment, in dollars, of Option A after t years.
Part C: What type of function, linear or exponential, would be best to describe the value of the investment over a fixed number of years using Option B? Explain your answer.
Part D: Write a function, b(t), to describe the value of the investment, in dollars, of Option B after t years.
Part E: Bridgette wants to invest in whichever option would increase her investment value by the greatest amount in 20 years. Will there be any significant difference in the value of Bridgette's investment after 20 years if she uses Option A over Option B? Explain your answer, and show the investment value after 20 years for each option.
Answer:
Part A:
Option A is a linear function
Part B:
a(t) = t × 100 + 1000
Part C:
Option B is an exponential function
Part D
[tex]b(t) = 1000 \times (1 + 0.1)^t[/tex]
Part E:
There will be a significant difference in the value of Bridget's investment after 20 yeas if she uses Option A over Option B
Step-by-step explanation:
The given parameters are;
The amount Bridgette has to invest = $1,000
The value of each investment option is given as follows;
Number of years [tex]{}[/tex] Option A [tex]{}[/tex] Option B
1 [tex]{}[/tex] 1100 1100
2 [tex]{}[/tex] 1200 1210
3 [tex]{}[/tex] 1300 1331
Part A:
Given that the first difference between subsequent data values are 2 - 1 = 1 and 1200 - 1100 = 100, 3 - 2 = 1 and 1300 - 1200 = 100 both of which are constant, the type of function that would be best to describe option A is a linear function
Part B:
The function a(t) for Option A is given as follows;
The rate of change of the function amount with time is (1300 - 1200)/(3 - 2) = 100
Therefore, comparing with the general form of a linear function, y = m·x + c, we have;
m = The rate of change of the function = 100
The y-intercept, the value of the amount a 0 time (the start of the investment) = c = 1000
The function in terms of t, a(t) = t × 100 + 1000
Part C:
The first difference of Option B are different but the first ratio given as follows;
1210/1100 = 1331/1210 = 1.1 = Constant which is the characteristics of an exponential variable
Therefore, the equation to describe the value of the investment in dollars, of Option B is an exponential function
Part D
We, have for an exponential function;
[tex]b(t) = 1000 \times (1 + r)^t[/tex]
When t = 1, we have;
[tex]b(1) = 1000 \times (1 + r)^1 = 1100[/tex]
∴ 1 + r = 1100/1000 = 1.1
r = 1.1 - 1 = 0.1
We check for t = 2, to get;
[tex]a(2) = 1000 \times (1 + 0.1)^2 = 1210[/tex]
We check for t = 3, to get;
[tex]b(3) = 1000 \times (1 + 0.1)^3 = 1331[/tex]
The function b(t) to describe the value of the investment in dollars, of Option B after t years is [tex]b(t) = 1000 \times (1 + 0.1)^t[/tex]
Part E:
The investment value after 20 years is given as follows;
For Option A, we have;
a(20) = 20 × 100 + 1000 = 3000
For Option B, we have;
[tex]b(20) = 1000 \times (1 + 0.1)^{20} \approx 6727.5[/tex]
Therefore, the difference in the investment value after 20 years for Option B and Option A is approximately $6727.5 - $3000 = $3727.5 which is significant.

Answer:
divde 81/3 to find 27
Step-by-step explanation:
The mixed fraction 8( 1/3 ) in the form of the proper fraction will be ( 25 / 3 ).
What is a fraction?Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction can also be an ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.
A mixed fraction is one that has both a quotient and a remainder. A mixed fraction is, for instance, 2 1/3, where 2 is the quotient and 1 is the remainder.
Given mixed fraction is 8 ( 1 / 3 ). The fraction will be solved by multiplying the whole number with the denominator and adding the numerator.
8 ( 1/3 ) = ( 24 + 1 ) / 3
8 ( 1/3 ) = ( 25 ) / 3
Therefore, the mixed fraction 8( 1/3 ) in the form of the proper fraction will be ( 25 / 3 ).
