Answer:
The coordinates of the point that divides the line internally in the given ratio is (7,3)
Step-by-step explanation:
To find this coordinates, we use the in renal division formula
we have this as;
(x,y) =( nx1 + mx2)/(m + n) , (ny1 + my2)/(m + n)
(x1,y1) = (4,-3)
(x2,y2) = (8,5)
(m,n) = (3,1)
So, substituting these values, we have ;
(x,y) = (1(4) + 3)8))/(3 + 1) , (1(-3) + 3)5)/(1 + 3)
(x,y) = (28)/4, (12/4)
(x,y) = (7,3)
Substitute the value n = 4 in the expressions
2n
n + 2
3(n+4)
Step-by-step explanation:
Given n = 4
2n = 2* 4= 8
n + 2 = 4 + 2 = 6
3(n + 4) = 3( 4 + 4) = 3 * 8 = 24

The radius of a circle is 4 meters. What is the circle's circumference?
r=4m
Use 3.14 for pie
This value is approximate because pi = 3.14 is approximate
===========================================================
Work Shown:
r = 4 = radius
pi = 3.14 approximately
C = circumference
C = 2*pi*r
C = 2*3.14*4
C = 25.12
The circumference is approximately 25.12 meters.
Side note: The circumference is the same as the perimeter of a circle.

-5x + 11 = -8(4 + 6x) What are the steps?
Answer:
[tex]x = - 1[/tex]
Step-by-step explanation:
[tex] - 5x + 11 = - 8(6x + 4)[/tex]
[tex] = > - 5x + 11 = - 48x - 32[/tex]
Lets keep the variable terms in L.H.S. and the constant terms in R.H.S.
[tex] = > 48x - 5x = - 32 - 11[/tex]
[tex] = > 43x = - 43[/tex]
Lets divide 43 on both the sides.

What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
3 ( x - 2 ) > 15 be equation (1)
On simplifying the equation , we get
3x - 3 ( 2 ) > 15
3x - 6 > 15
Adding 6 on both sides of the inequality equation , we get
3x > 21
Divide by 3 on both sides of the inequality equation , we get
x > 21/3
x > 7
Therefore , the value of x is greater than 7
Hence , the inequality equation is x > 7

if 3/4 of a cup of yogurt is 80 calories, how many calories are in 1/4 of a cup?
Answer:
[tex]\boxed{\textsf {One fourth cup of yogurt has 26.66 calories. }}[/tex]
Step-by-step explanation:
Given that ¾ of a cup of yogurt is 80 calories and we need to find the calories in ¼ of a cup . So here we can use unitary method to find the calories.
=> ¾ cup of yogurt has 80 calories
=> 1 cup of yogurt has 80 ÷ ¾ calories .
=> ¼ cup of yogurt has 80 × 4/3 × 1/4 calories = 26.66 calories .
★ Hence ¼ of yogurt has 26.66 calories.PLEASE HELP!!!

Brian and Mark are fishing. They both catch a fish. Brian's fish weighs 17
pounds less than Mark's fish. Mark's fish weighs 22 pounds
PLEASE HURRY.
Answer: 5 pounds
Step-by-step explanation:
We need to find how much Brian's fish weighs. We know that Mark's fish weighs 22 pounds, and Brian's fish weighs 17 pounds less than Mark's fish. To find how much Brian's fish weighs, we can subtract 17 from 22.
22 - 17 = 5.
Therefore, Brian's fish weighs 5 pounds.

The club treasurer counted 300 tickets sold for a total of $650. Write and solve a system of equations to determine how many adult and student tickets were sold.
Answer:
50 adults and 250 students tickets were sold
Step-by-step explanation:
Given data
Let the number of adults be x and students be y
3x+2y=650------1
x+y= 300---------2
from 2
x= 300-y
put the value of x in 1
3(300-y)+2y= 650
900-3y+2y= 650
900-y= 650
900-650= y
y=250
put the value of y in 2
x+250= 300
x= 300-250
x= 50
Hence 50 adults and 250 students tickets were sold

On 9th May, 2009, there were 3440 people in the world with swine flu. Of these people, 1639 were in the USA. The 3440 people who had swine flu on 9th May was an increase of 37.6% on the number of people who had swine flu on 8th May. Calculate the number of people who had swine flu on 8th May.
Answer:
2500
Step-by-step explanation:
let a represent the number of people that had swine flu on the 8th of May
a increased by 37.6% on the 9th of May. The 37.6% increase is equal to 3440
the equation that can be used to represent this is:
a x 1.376 = 3440
to find a, divide both sides by 1.376
a = 2500
