5:3. If there are 18 more boys than girls, work out how many people there are in total.
Answers
Answer:
72
Step-by-step explanation:
Since there are 18 more boys than girls, we know that in the ratio 5:3, 5 is for boys and 3 is for girls.
Now, we can set up a proportion to first find the number of girls.
Let's name the number of girls x.
The number of boys is x+18.
3/5=x/x+18
Cross multiply.
5x=3(x+18)
Distribute.
5x=3x+54
Subtract 3x from both sides.
2x=54
Divide both sides by 2.
x=27
There are 27 girls.
We know that there are 18 more boys that girls.
27+18=45
There are 45 boys.
Add the number of boys and girls together to find total number of people.
27+45=72
There are 72 people in total.

How can you determine if a point is a solution to a system of linear equations?
Please Help!
Answers
Answer:
You can substitute the x value of coordinate (x,y) in the equation. If the outcome = the y value in the coordinate (x,y), then you have determined it to be on the system of linear equations.
Step-by-step explanation:
Point P has a coordinates: ( Px , Py ).
You can choose which value is easy to substitute. Eighter start with the Py or you could start with the Px. It could save you time if you pick the right one for the job.
If you want to verify if any point is valid in any (linear) equation(s), you can:
a) substitute the x value of coordinate (x,y) in the equation, and if the outcome has the same value as y in the coordinate (x,y), then that point is a valid solution of the (linear) equation.
b) substitute the y value of coordinate (x,y) in the equation, and if the outcome has the same value as x in the coordinate (x,y), then that point is a valid solution of the (linear) equation.
Answer:
You can substitute the x value into the equation if the answer for y is the same for the y coordinate you will have your answer.

Answers
Answer:
B and D
Step-by-step explanation:
i took this test
The roots of the equation will be - 1 - √6 and - 1 + √6. Then the correct options are B and D.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
The quadratic equation is given below.
x² + 2x - 5 = 0
The solution of the quadratic equation will be
x² + 2x - 5 = 0
Add 1 on both sides, then the equation will be
x² + 2x + 1 - 5 = 1
x² + 2x + 1 = 1 + 5
(x + 1)² = 6
Taking square root on both sides, then the equation will be
x + 1 = ±√6
x = - 1 ±√6
Then the roots of the equation will be - 1 - √6 and - 1 + √6.
Then the correct options are B and D.

The state fair is a popular field trip destination. This year the senior class at High School A and the senior class at High School B both planned trips there. The senior class at High School A rented and filled 1 van and 10 buses with 258 students. High School B rented and filled 8 vans and 5 buses with 264 students. Each van and each bus carried the same number of students.How many students can a van carry? How many students can a bus carry?
Answers
Answer:
The van holds 18 students
The bus holds 24 students
Step-by-step explanation:
v = van b = bus
High School A
1v+10b = 258
High School B
8v+5b = 264
Multiply the second equation by -2
-16v - 10b = -528
Add this to the first equation
-16v - 10b = -528
1v+10b = 258
---------------------------
-15v = -270
Divide each side by -15
-15v/-15 = -270/-15
v =18
The van holds 18 students
Now we need to find the number the bus holds
1v+10b = 258
18 + 10b = 258
Subtract 18 from each side
18-18+10b = 258-18
10b=240
Divide each side by 10
10b/10 =240/10
b = 24
The bus holds 24
Answer:
Van: 18
Bus: 24
Step-by-step explanation:
V + 10B = 258
V = 258 - 10B
8V + 5B = 264
8(258 - 10B) + 5B = 264
2064 - 80B + 5B = 264
75B = 1800
B = 24
V = 258 - 10(24) = 18

A new car is purchased for 24000 dollars. The value of the car depreciates at 15% per year. To the nearest tenth of a year, how long will it be until the value of the car is 10000 dollars
Answers
The value of the car will be $10000 after 2.5 years
The cost price of the car = $24000
Rate of depreciation, r = 15%
r = 15/100
r = 0.15
The final value of the car after depreciation, A = $10000
To get the time for depreciation, use the formula below and solve for t
[tex]A=P(1-r)^t[/tex]
Substitute P = 24000, A = 10000, and r = 0.15 into the equation above
[tex]10000=15000(1-0.15)^t\\\\\frac{10000}{15000} = 0.85^t\\\\0.85^t=0.67\\\\t (ln0.85)=ln0.67\\\\-0.163t=-0.4\\\\t=\frac{-0.4}{-0.163} \\\\t=2.5[/tex]

Step 2: Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.)
Step 3: Simplify (or reduce) the fraction
