Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtraction Property of EqualityStep-by-step explanation:
Let's set Huilan's age to h and Thomas's age to t.
Since Huilan is 13 years younger than Thomas, we can write:
h = t - 13The sum of both their ages is 41, so let's combine the variables h and t together.
h + t = 41We said that h = t - 13, so substitute this value into the equation.
(t - 13) + t = 41Combine like terms.
2t - 13 = 41Add 13 to both sides of the equation.
2t = 54Divide both sides of the equation by 2.
t = 27Thomas's age is 27 years old.

1.In how many ways can 3 boys and 6 girls sit in a row of 4 chairs?
2.In how many ways can 8 cars line up a car?
3.In how many ways can a group of 8 friends sit around a circular table?
plss help
Answer:
1) 3024 ways
2) 40320 ways
3) 5040 ways
Step-by-step explanation:
1) there are 3 boys and 6 girls. Thus, total number = 9 people.
There are four rows of chairs.
Thus, number of ways of being sitted is;
9P4 = 9!/(9 - 4)! = 3024 ways
2) number of ways = 8! = 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 40320 ways
3) since circular arrangement, then number of ways is; (n - 1)!
Thus,answer is; (8 - 1)! = 5040 ways

If the temperature outside is 60 degrees at 6 pm and then drops by 15% at 10 pm, what is the temperature at 10 pm?
Answer:
51 degrees
Step-by-step explanation:=Given data
Temperature at 6pm = 60 degrees
percent drop= 15%
= 15/100*60
=0.15*60
=9 degrees
Hence the temperature at 10 pm is 60-9= 51 degrees
Write a system of equations, with one equation describing the cost to bowl at Bowl-o-Rama and the other describing the cost to bowl at Bowling Pinz. For each equation, let x represent the number of games played and let y represent the total cost.
Complete question :
Write a system of equations, with one equation describing the cost to bowl at Bowl-o-Rama and the other describing the cost to bowl at Bowling Pinz. For each equation, let x represent the number of games played and let y represent the total cost.
Bowl-O-Rama rents shoes for $2 and each game cost $2.50
Bowling Pinz rents shoes for $4 and each game cost $2
Answer:
Bowl-O-Rama:
y = $2 + $2.50x
Bowling pinz:
y = $4 + $2x
Step-by-step explanation:
The total cost is the sum of shoe rental plus the product of the unit game rate and the number of games played.
Total cost, y
x = number of games played
Bowl-O-Rama:
y = Shoe rent + (unit rate per game * number of games)
y = $2 + ($2.50 * x)
y = $2 + $2.50x
Bowling Pinz :
y = Shoe rent + (unit rate per game * number of games)
y = $4 + ($2 * x)
y = $4 + $2x

Answer:
C: Life insurance policy amounts should factor in how much it would take to maintain the standard of living for the beneficiaries
Step-by-step explanation:
The statement is true for life insurance coverage
Life insurance policy amounts should factor in how much it would take to maintain the standard of living for the beneficiaries.
What is Life insurance coverage?A contract between an insurance policy holder and an insurance company in which the insurer agrees to pay a quantity of money in exchange for a premium upon the demise of an insured person or after a specific amount of time is known as life insurance.
In order to provide a death benefit in exchange for paying premiums, life insurance functions. One common kind of life insurance, called term life insurance, only lasts for a predetermined period, such 10 or 20 years. Although the death benefit of permanent life insurance likewise lasts during the policyholder's lifetime as long as premiums are paid, it does not.
Thus, the true statement is
Life insurance policy amounts should factor in how much it would take to maintain the standard of living for the beneficiaries.

Describe how to determine the average rate of change between x = 3 and x = 5 for the function f(x) = 3x^3 + 2.
include the average rate of change in your answer.
Step-by-step explanation:
step 1. we will denote the average rate of change as r.
step 2. r = (f(5) - f(3))/(5 - 3)
step 3. r = (375 - 81)/2
step 4. r = 294/2
step 5. r = 147.

Step-by-step explanation:
On a map, you trace your route and come to a fork in the road. Two diverging roads split from a common point and form an angle. The point at which the roads diverge is the vertex. An angle separates the area around it, known in geometry as a plane, into two regions. The points inside the angle lie in the interior region of the angle, and the points outside the angle lie in the exterior region of the angle.
Once you get to know the types of angles and how to measure and create your own, you’ll have picked up valuable geometry skills that will help you prove even the most complex geometric puzzles.
Find the measure of the missing angle.
A box indicates a 90° angle.
So to find m<a, we can setup the equation 41 + a = 90.
Now subtract 41 from both sides to get a = 49.

O x=2sqrt3 y=4
O x=8sqrt7 y=4sqrt21
O x=8sqrt3 y=8sqrt3
O x=4sqrt21 y=8sqrt7
Answer:
x= 90 degree
y= 43 degree
Step-by-step explanation:
We have been given an isosceles triangle being two sides equal AB and AC
By the property of isosceles triangle
The sides which are equal will have same base angle
Hence, ∠ABC=∠ACB=
We know that sum of angles of triangle is
∠ABC+ ∠ACB+∠BAC= (1)
Since, ∠BAC is the bisector so, ∠BAD and ∠DAC are equal which is
Now, substituting the values in (1) we get:
Now, we will consider ΔABD to find x
,∠ADB=∠ABD=
Now, Apply the sum of angles of triangle is we get:
Answer:
x = 8[tex]\sqrt{7}[/tex]
y = 4[tex]\sqrt{21}[/tex]
Step-by-step explanation:
use the altitude rule to find the height of the triangle first
12/h = h/16
h² = 12x16
h = [tex]\sqrt{192}[/tex]
h = [tex]\sqrt{4}[/tex][tex]\sqrt{4}[/tex][tex]\sqrt{4}[/tex][tex]\sqrt{3}[/tex] = 8[tex]\sqrt{3}[/tex]
now you can use the Pythagorean Theorem with height of 8[tex]\sqrt{3}[/tex] along with the other leg of 12 to find 'y'; which comes out to be [tex]\sqrt{336}[/tex] or [tex]\sqrt{4}[/tex][tex]\sqrt{4}[/tex][tex]\sqrt{21}[/tex]
then use the Pythagorean Theorem with height of 8[tex]\sqrt{3}[/tex] along with the other leg of 16 to find 'x'; which comes out to be [tex]\sqrt{448}[/tex] or [tex]\sqrt{4}[/tex][tex]\sqrt{4}[/tex][tex]\sqrt{4}[/tex][tex]\sqrt{7}[/tex]
