Find the values of x and y that make these triangles congruent by the HL theorem
Answer:
A. x = 3, y = 2
Step-by-step explanation:
The hypotenuse and the length of one leg of one right triangle must be equal to the hypotenuse and corresponding length of the one leg of the other ∆ for both triangles to be equal by the HL Congruence Theorem.
Thus, let's find x and y by setting the corresponding lengths of the two right ∆s equal to each other.
Therefore:
x = y + 1 ----› eqn. 1
2x + 3 = 3y + 3 ----› eqn. 2
Substitute x = (y + 1) into eqn. 2, and solve for y.
2x + 3 = 3y + 3 ----› eqn. 2
2(y + 1) + 3 = 3y + 3
2y + 2 + 3 = 3y + 3
2y + 5 = 3y + 3
Collect like terms
2y - 3y = -5 + 3
-y = -2
Divide both sides by -1
y = 2
Substitute y = 2 into eqn. 1.
x = y + 1 ----› eqn. 1
x = 2 + 1
x = 3

In a class of 23 students, 16 have a brother and 15 have a sister. There are 11 students
who have a brother and a sister. What is the probability that a student chosen
randomly from the class is an only child?
Answer:
3/23Step-by-step explanation:
11 students have a brother and a sister16 students have a brother and 16 - 11 = 5 have a brother only15 students have a sister and 15 - 11 = 4 have a sister onlySo out of 23 students:
11 + 5 + 4 = 20 have a brother or sister or bothAnd therefore
23 - 20 = 3students have no brothers or sisters
The required probability is:
3/23If (x − 2) ∶ 5 = 7 ∶ 9, then find the value of x.

Mike has a credit rating of 720. Tyler has a credit rating of 560. Mike and Tyler apply for identical loans from Park Bank. Mike is approved for a loan at 3.2% interest, and Tyler is approved for a loan that charged 3 percentage points higher because of his inferior credit rating. What interest rate is Tyler charged?
Answer:
6.2%
Step-by-step explanation:
Credit rating is an evaluation of the credit risk of a borrower, that how often a person is going to repay their debt, by credit rating it predicts the ability of the debtor to payback.
Mike has credit rating = 720
Tyler has credit rating = 560
Both are approved for loan. Mike's Credit score is higher, which means he is a much safer debtor as compared to Tyler. Mike will be able to pay back much easily than Tyler. Therefore Mike interest rate is 3.2%
Interest rate of Tyler is higher as he is not that trusted and has low Credit rating. Tyler is approved for a loan that charged 3 percentage points higher because of his inferior credit rating so it interest on the loan will be
Interest = 3.2%+3% = 6.2%

Step-by-step explanation:
Jamie went to the movies with her twin sister, Jenna. They bought one large soda for $4.95 and 3 boxes of candy. Each box of candy cost the same amount. They spent a total of $18.45. Select the equation that best represents how you would solve for c, the cost of each box of candy?
Answer:
The Equation we can use to solve for the cost of each box of candy =
4.95 + 3b = 18.45
The cost of each box of candy = $4.5
Step-by-step explanation:
Let the number of boxes of candy be represented by: b
Each box of candy cost the same amount
Hence from the question above, we have the Equation:
$4.95 + 3b = $18.45
4.95 + 3b = 18.45
3b = 18.45 - 4.95
3b = 13.5
b = 13.5/3
b = 4.5
The cost of each box of candy = $4.5
A theater is showing 2 comedies, 1 musical, and 5 action films. Each movie has 3 matinee showtimes and 7 evening performances. Each type of movie and showtime is equally likely to be chosen. If 12,400 people see a movie, how many will be expected to choose a musical during an evening showtime? A 1,085 C 1,240 B 1,189 D 1,550
Answer: 1550
Step-by-step explanation:
Number of people to see the movie = 12400
Number of comedies = 2
Number of musical = 1
Number of action films = 5
The number of people that'll be be expected to choose a musical during an evening showtime will be:
= 1/8 × 12400
= 1550

Answer:
first car : 115 liters
second car: 135 liters
Answer:
car 1 = 173.08 liters
car 2 = 76.92 liters
Step-by-step explanation:
the first step is to find what ratio of car 1 is to car 2
that is 18:8
total ratio is 26
the combination of car 1 and 2 = 26
the total km = 3350
total fuel = 250 liters
car 1 = 18 x 250 liters
26
= 173.08 liters
car 2 = 8 x 250 liters
26
= 76.92 liters
173.08 + 76.92 = 250

m + n.
Answer:
[tex]xm+nxy=14[/tex]
Step-by-step explanation:
Given that x = 2, y = 3, m = 4 and n= 1.
Putting all the given values to get the value of xm+nxy.
So, the value of [tex]xm+nxy=2\times 4 + 1\times 2 \times 3=14[/tex]
Hence, [tex]xm+nxy=14[/tex].

Solve the equation: 5 + 2(3 + 2x) = x + 3(x + 1)
Answer:
No solutions
Step-by-step explanation:
In this question, you would be solving for x.
Solve:
5 + 2(3 + 2x) = x + 3(x + 1)
Use the distributive property.
5 + 6 + 4x = x + 3x + 3
Combine like terms.
11 + 4x = 4x + 3
Subtract 4x from both sides.
11 = 3
Since we don't have an "x value", there are no solutions.
"No solutions" would be your answer.

2x + 10 =- 4x – 9
Answer:
x = -19/6
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
2x + 10 = -4x - 9
Step 2: Solve for x
Add 4x on both sides: 6x + 10 = -9Subtract 10 on both sides: 6x = -19Divide 6 on both sides: x = -19/6Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 2(-19/6) + 10 = -4(-19/6) - 9Multiply: -19/3 + 10 = 38/3 - 9Add/Subtract: 11/3 = 11/3Here we see that 11/3 does indeed equal 11/3.
∴ x = -19/6 is the solution to the equation.

During an online sale, you buy three sweatshirts and two pairs of sweatpants for $85.50. Later you buy three more sweatshirts and four more pairs of sweatpants for $123. (You can never have too many sweats during a pandemic). What is the sale price of each sweatshirt and each pair of sweatpants?
Answer:
Step-by-step explanation:
let
x = price of a sweatshirt
y = trice of sweatpants
three sweatshirts and two pairs of sweatpants for $85.50
3x + 2y = 85.50
three more sweatshirts and four more pairs of sweatpants for $123
3x + 4y = 123
by solving the system of equations
3x + 2y = 85.50
3x + 4y = 123
we find
x = $16
y = $18.75
3x + 4 = -11 what is the value of x in this equation?
Answer:
Step-by-step explanation:
3x + 4 = - 11
3x = - 11 - 4
3x = - 15
x = - 15/3
x = - 5
Answer:
x = -5
Step-by-step explanation:
3x + 4 = -11
Isolate 3x.
3x = -11 - 4
Evaluate.
3x = -15
Find x.
x = -15 ÷ 3
x = -5

Answer:
25 metres per second
Step-by-step explanation:
just divide 100 by 4 and you will get the answer.☺️☺️
Answer:
25 m/s
Step-by-step explanation:
train a travels at 12.5 m/s and will arrive at 100m in 7s.
train b arrives at the same distance, 100m, in 4s. so that means train b is going at 100m/4s and then simplify that
therefore train b is moving at 25m/s
