The total charge for your party was $375. Translate this information into an equation using x to represent the number of guests at your party
Answers
Answer:
There would be 25 guests at the party.
Step-by-step explanation:
First, subtract $150 from $375
Then, divide the difference by $9
The quotient is the answer
So, [tex]x = 25[/tex] guests at the party
Equation:
[tex]375 - 150 = 225[/tex]
[tex]225 \div 9 = x[/tex]
[tex]x = 25[/tex] guests at the party.
Simple equation:
[tex](375 - 150) \div 9 = x\\x = 25[/tex]

You purchase $7,000 from a store offering 10% down, no interest if paid in full by three months.
$5,000 is paid before deadline, how much is owed if monthly interest is 2.49%?
Owed: $____________
Answers
The $7,000 worth of purchase and payment of $5,000 before the three months deadline gives the amount owed at 2.49% monthly compound interest rate as $2,153.15
Owed: $2,153.15
What is a compound interest rate?Compound interest accounts for the interest that is earned on an interest, such that the interest rate is compounded on an initial amount.
The given parameters are;
The amount of the items purchased from the store = $7,000
The amount of down payment required = 10%
The amount paid in three months = $5,000
Monthly interest on amount owed after three months = 2.49%
Required;
The amount owed after payment of $5,000 before three months
Solution;
Using the compound interest formula, we have;
[tex] \displaystyle{A = P \cdot \left(1 + r \right)^{n} }[/tex]
Where;
A = The amount owed
P = The amount loaned = $7,000 - $5,000 = $2,000
r = Monthly interest rate = 2.49%
n = The number of months = 3 months
Which gives;
[tex] \displaystyle{A = 2000 \times \left(1 + 0.0249 \right)^{3} \approx 2153.1509}[/tex]
The amount owed (for the 3 months period) is approximately $2,153.15

The resulting exponent form is, 1/9¹⁰
Exponent:
Exponent is used to show repeated multiplication of a number by itself. For example,
7 × 7 × 7 can be represented as 7³
Here, the exponent is ‘3’ which stands for the number of times the number 7 is multiplied.
Given,
Here we have the exponent form is,
9⁻⁸x9⁻²
Here we have to use the product property and then we have to get rid of negative exponents.
First step is to use the product property,
We know that, the product property states that,
for any non-zero term a,
yᵃ x yᵇ = yᵃ⁺ᵇ
where a and b are real numbers.
So, the given expression is written as,
=> 9⁻⁸⁺⁽⁻²⁾
=> 9⁻⁸⁻²
=> 9⁻¹⁰
Now the second step is to get rid of the negative components,
As per the rule, the exponent is negative, we can change the exponent into positive by writing the same value in the denominator and the numerator holds the value 1.
So, the value is,
=> 9⁻¹⁰ = 1/ 9¹⁰

(The formula R⋅T=D , where R is the rate of speed, T is the time, and D is the distance can be used.) How fast did Car B travel? Enter your answer in the box.
Answers
Car B travelled with the rate of speed of 40mph .
In the question ,
it is given that ,
Car B travelled 5mph slower than Car A .
let the rate of speed at which Car B travelled be x mph.
So , the rate of speed of Car A is = (x+5) mph
Car A travelled the distance in 4 h , with the speed of (x+5) mph ,
the value of T = 4 h and R = (x+5) mph
So, by the formula R*T=D ,
we get ,the distance travelled by Car A = 4(x+5) miles .
Car B travelled the distance in 4.5 h , with the speed of x mph .
the value of T= 4.5h and R = x mph
So, by the formula R*T=D,
we get , the distance travelled by Car B = 4.5*x = (4.5x) miles .
Since , both the cars travelled the equal distance ,
we get ,
4(x+5) = 4.5x
4x+20=4.5x
4.5x-4x = 20
0.5x= 20
x = 40
Therefore , the rate of speed of Car B is 40 mph.

(C) The value of x is 6 and the measure of angle 27x - 5 is equal to 130°.
The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.
Two parallel lines and a transversal cutting them are given. The two angles are 130° and 27x - 5.
Both angles are exterior angles.
The angles 130° and 27x - 5 are alternate exterior angles and are equal.
Now,
130° = 27x - 5
Adding 5 on each side.
27x - 5 + 5 = 130 + 5
27x = 135
Dividing each side by 27
x = 5°
Therefore, substituting the value of x.
27x - 5 = 27(5) - 5 = 135 - 5 = 130°
Hence, the measure of angle 27x 0 5 = 130°

how could you use the relationship between addition and subtraction with counting up to find 3 1/4 - 1 3/4
Answers
Answer:
1 1/2
Explanation:
We can illustrate the relationship between addition and subtraction using the following example:
If we have 5 - 3 = 2, then we can say that 2 + 3 = 5
So, in this case, the result of 3 1/4 - 1 3/4 is a number that added to 1 3/4 is equal to 3 1/4. Then, the answer will be 1 2/4 because:
[tex]1\frac{3}{4}+1\frac{2}{4}=\frac{7}{4}+\frac{6}{4}=\frac{13}{4}=3\frac{1}{4}[/tex]Because 1 3/4 is equivalent to 7/4 and 1 2/4 is equivalent to 6/4.
Finally, 2/4 is equivalent to 1/2, so we can rewrite the result 1 2/4 as follows:
1 2/4 = 1 1/2
Therefore, the answer is 1 1/2

I have made an example using the first pair. I rotated the first polygon (the red one) to show that they are indeed congruent.
Following the same process, we can see that pairs 3 and 4 are also congruent.
Pair 2 are not congruent because the green rectangleis longer.

To find the y =?
Now, According to the question:
Because the graph of a quadratic goes through point (-8 ,0) and point (2, 0)
So, supposing the equation of the quadratic function is
y = a [x - (-8)] (x - 2) = a (x + 8)(x - 2)
The graph passes through the point (-6, 16)
So, -16 = a(-6 + 8)(-6 -2)
=> -16 = a x 2 x (-8)
=> a = 1
So, y = (x + 18)(x - 2)
y = [tex]x^{2}[/tex] + 8x - 2x - 16

Angle 1: Angle pAngle 2: Angle with a measure of 57 degreesAngle 3: Angle with a measure of 90 degrees i.e. a right-angled triangleAlso, from the attached figure:
We can see that the three angles named above are formed by lines that meet at a point (say the point of origin)
When multiple lines meet at a point, the sum of the angles formed at this point is 360 degrees
This means that
Angle 1 + Angle 2 + Angle 3 = 360
Substitute the known values in the above equation
So, we have
p + 57 + 90 = 360
Evaluate the sum in the above equation
