I'm having a hard time with fractions, what is the sum of 2/5 and 2/4

Answers

Answer 1
Answer: We will go nice and slow...

to add fractions, you have to have a common denominator.....

that being said....a common denominator of (2)/(5) and (2)/(4) is 20...

So change the fractions...

(2)/(5) * (4)/(4) = (8)/(20)
and
(2)/(4) * (5)/(5) = (10)/(20)

Now, you can add..

(8)/(20)+ (10)/(20) = (18)/(20)   ((9)/(10) simplified)

Thus, your answer.


Answer 2
Answer: well first you need to get the same bottom number so the bottom number is 20 and the top will be first fraction top is 8 other fraction is 10 so your answer is 18/20

On a vertical line segment, point A is located at 50. Point B is located at 104. Point P is a point that divides segment AB in a ratio of 1:5 from A to B. Where is point P located?

Answers

Answer:

Step-by-step explanation:

Let the initial point on the line segment be O. If point A is located at 50 and point B is located at 104, then OA = 50 and OB = 104. Using the vector notation;

AO+OB = AB

(-OA)+OB = AB

-50+104 = AB

AB = 54

If point P divides the segment AB in a ratio 1:5, them AP:PB = 1:5

AP = 54/6

AP = 9

PB = 54-9

PB = 45

Hence the point P is located at 9 units from A and 45 units from B

A satellite television company charges a one-time installation fee anda monthly service charge. The total cost is modeled by the function
y = 40 + 90x. Which statement represents the meaning of each part
of the function?
(1) y is the total cost, x is the number of months of service,
$90 is the installation fee, and $40 is the service charge per
month.
(2) y is the total cost, x is the number of months of service,
$40 is the installation fee, and $90 is the service charge per
month.
(3) x is the total cost, y is the number of months of service,
$40 is the installation fee, and $90 is the service charge per
month.
(4) x is the total cost, y is the number of months of service,
$90 is the installation fee, and $40 is the service charge per
month.

Answers

Answer:

Option (2).

Step-by-step explanation:

A satellite T.V. company charges one time installation fees along with monthly service charge.

Total cost is modeled by the function y = 40 + 90x

Here y = Total cost charged by the company

A one time installation charges = $40

Service charge for a month = $90

and number of months for which service was used = x months

Therefore, Option (2) explains the function well.

the answer is 2 y= total installation cost. x is the variable representing the number of months of service and $40 is the fixed price while $90 is dependent on the xvalue
