Find two numbers if their sum is 7.2 and their difference is 2.7
Klio2033 [76]

Answer:

4.95 and 2.25

Step-by-step explanation:

x+y=7.2

x-y=2.7

Add equations

x+y + x-y= (2x-y+y)=2x

7.2+2.7=9.9

Therefore 2x=9.9 x=9.9/2=4.95

x=4.95

x+y=7.2

4.95+y=7.2

y=7.2-4.95=2.25

y=2.25

Aaron is 15 centimeters taller than Peter, and five times Aaron's height exceeds two times Peter's height by 525 centimeters. Th
Tatiana [17]
The system of linear equations that relates x and y:
x= 15 + y
5 x = 2 y+ 525
We will solve this system using substitution method:
5(15 + y)=2 y + 525
75 + 5 y = 2 y + 525
5 y - 2 y = 525 - 75
3 y = 450,           y = 450 : 3        y = 150
x = 15 + y           x = 15 + 150     x = 165
Answer: Aaron´s height is 165 cm and Peter´s height is 150 cm.

Karen bakes cookies. She has observed that the number of cookies that turn out well in each batch varies with the size of the ba
mestny [16]

Substitute the values of the size of the 5 batches to the model.

For example

@x = 20

f(20) = 2*20 – 23 = 17

f(25) = 2*25 – 23 = 27

f(26) =29

f(27) = 31

f(34) = 45

 

Therefore the answer is the first choice (17, 27, 29, 31, 42)

CAN ANYONE HELP ME!!! THIS IS SO HARD
makkiz [27]

The studio Cost per day as a function of the number of hours used by the sound technician and the inequality which models the data is :

  • T(n) = 225 + 80n
  • $205 ≤ (225 + 80n) ≤ $545

<u>Total studio cost</u> :

(studio fee per day + sound technician fee per hour)

If the Number of hours spent in studio = n

Total studio cost, T(n) = 225 + 80n

Amount at hand = $205

Additional earning from pre-orders = $340

This means that minimum amount Jenna can afford = amount at hand = $205

The maximum amount Jenna can afford = (Amount at hand + additional earning) = ($205 + $340 = $545)

Therefore in other to afford studio cost :

Minimum ≤ Studio cost ≤ maximum amount

$205 ≤ (225 + 80n) ≤ $545
