Answer: x = 25
Step-by-step explanation:
(x-7) = 36/2
x-7 = 18
x = 18 +7
x = 25
Answer: x = 1 and x = 13.
Step-by-step explanation: To solve the equation (x - 7)^2 = 36, we can first rewrite the equation as x^2 - 14x + 49 = 36.
Next, we can rewrite the equation as x^2 - 14x + 13 = 0.
To solve for x, we can then use the quadratic formula:
x = (-b +/- sqrt(b^2 - 4ac)) / (2a)
where a = 1, b = -14, and c = 13.
Substituting these values into the formula, we get:
x = (14 +/- sqrt(14^2 - 4(1)(13))) / 2
x = (14 +/- sqrt(196 - 52)) / 2
x = (14 +/- sqrt(144)) / 2
x = (14 +/- 12) / 2
The values of x are therefore 1 and 13.
Therefore, the correct answer is x = 1 and x = 13.

What is Expression?A mathematical expression is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.)
It is possible to compare expressions and phrases. In English, a phrase by itself could contain an action, but it doesn't constitute a full sentence.
As instances of expressions and how they connect to word phrases, consider the following:
Example: 3 + 7
The phrase "the product of three and seven"
Cost of Ticket for each student cost = $10
Cost of Ticket for each Teacher cost = $20
Let the total students be x
and, total number of teacher will be y
Total cost= 10x + 20y
As museum gives 20 % rebate for promotion
So, now total cost will be {10x + 20y} - 20/100 {10x + 20y}
So the required Expression would be 0.8{10x + 20y}.

Write the equation of the line passing through the points (-3,3) and (3,1).
The equation of the line is?
Answer:
y = -1/3x + 2
Step-by-step explanation:
Slope-intercept form of a linear equation is written as:
y = mx + b, where x and y are coordinates from one of the points on the line, m is the slope, and b is the y-intercept.
1. You'll first want to find the slope, m. Slope can be calculated from two points by using the equation (y1 - y2)/(x1 - x2). If you plug your two points into this equation for x and y (making sure that y1 and x1 are from the same point and y2 and x2 are from the other), you'll get,
(3 - 1)/(-3 - 3) = 2/-6 = -1/3
m = - 1/3
2. You can then plug your slope, m, into the slope-intercept form of the equation. Using one of your points (doesn't matter which, but I'll use (3,1)), you can solve for b, your y-intercept.
1 = -1/3(3) + b
1 = -1 + b
b = 2
3. Plug the variables into the equation.
For your final equation, plug the slope, m, and y-intercept, b, that you just found.
y = -1/3x + 2

Ron did not pay his credit card bill in full last month. He wants to pay it in full this month. On this month's bill, there is a mistake in the average daily balance. The
credit card company lists the average daily balance on his bill as $510.50. Ron computed it himself and found that it is $410.50.
a. The APR is 18%. What finance charge did the credit card company compute on Ron's bill?
b. If Ron's average daily balance is correct, what should the finance charge be?
The credit card company calculated a finance charge of $7.66 on Ron's bill if the annual percentage rate is 18%.
What is finance charges?A finance charge is any fee that represents the cost of credit or borrowing. It is the interest and fees charged for certain types of credit. It includes not only interest but also other charges like financial transaction fees.A financing charge is, to put it simply, any fee incurred when using credit. A finance charge is the total of all fees that are imposed incidentally to the extension of credit by the creditor and are paid directly or indirectly by the person to whom credit is extended, according to the Truth in Lending Act's legal definition.Your monthly statement from your credit card company will include a list of all finance charges in addition to your purchases and payments. Your card issuer will determine how your finance fee appears on your statement.The finance charge is the product of the average daily balance and the monthly percentage rate.
The annual percentage rate (APR) is 18% or 0.18.

Omari buys a computer for $1,099. He

payments for the computer are $144. How
many months will it take Omari to finish
paying off the computer?
It will take 6 months for Omari to finish paying off the monthly payment for the computer.
What is the monthly payment?
The amount paid each month to repay the loan over the course of the loan is known as the monthly payment. When a loan is taken out, not only the principal, or the original lent amount, but also the interest that accrues, must be repaid.
Given, the total price of the computer = $1,099
down payment = 20% of $1,099 = $219.8
The remaining amount = $1,099 - $219.8 = $879.2
monthly payments for the computer = $144
Then, the total months to pay = 879.2/144 = 6 months
Hence, it will take 6 months for Omari to finish paying off the monthly payment for the computer.

The area of a triangle is 36 cm2. The height of the triangle is 6 cm less than the base. What is the height of the triangle?.
Answer:
[tex]\huge{\boxed{\text{The height of the triangle is 6cm.}}}[/tex]
Step-by-step explanation:
This question requires us to use a system of equations.
The area of a triangle is (1/2) * (base) * (height).
Thus, if b = base, and h = height
[tex]\frac{1}{2} bh=36[/tex]
Additionally, from the problem, we know:
[tex]b=h+6[/tex]
Then, via substitution, we can get
[tex]\frac{1}{2} *(h+6)*h=36[/tex]
Then, simplify:
[tex]\frac{1}{2} h^2+3h=36[/tex]
[tex]\frac{1}{2} h^2+3h-36=0[/tex]
[tex](\frac{1}{2} h-3)(h+12)=0[/tex]
Thus, the height must equal either 6 or -12, and because height cannot intrinsically be negative, the height must be 6.

Please help me!At the beginning of spring, Jin planted a small sunflower in his backyard. The sunflower's height in inches, hh, after ww weeks, is given by the equation h=18+2.5wh=18+2.5w. What could the number 18 represent in the equation?
Answer:
The equation of the sunflower's height is h = 18+2.5w
Since the number 18 remains constant regardless of the change in number of weeks, we know that at the start h (w=0) = 18 + 2.5 x 0.
This means that, when Jin planted the sunflower, the sunflower's height was already 18 inches.
For such a reason, we can conclude that the number 18 could represent the sunflower's height at the start (original height).

Two types of alien live on the planet Starlight: Zoomas have 3 eyes and 2 legs and Popsies have 4 eyes and 5 legs. How many of each type of alien might there be if there are 38 eyes and 37 legs
Answer:
Below
Step-by-step explanation:
(3y + 2l )z + (4y + 5l) p = 38y+37 l <=======given ( y = eyes , l = legs)
z 2l + p5l = 37 l <===separating out the' l ' part
2z + 5p = 37
3y z + 4y p = 38y <====== taking out the 'y' part
3z + 4 p = 38 Solve the two underlined simultaneous equations
multiply first one by - 1.5 then add to second one to get:
-3z -7.5p = - 55.5 <===== solve for p
-3.5 p = - 17.5
p = 5 then z = 6
