A bird can lay either white or brown eggs. Three white eggs
and
two brown eggs have a mass of 13 grams, while five white eggs
and four brown eggs have a mass of 24 grams. Find the mass
of a brown egg and of a white egg.

Answers

Answer 1

Answer:

Mass of brown egg = 3.5 grams

Mass of white egg = 2 grams

Step-by-step explanation:

Let

Mass of brown eggs = x

Mass of white eggs = y

3y + 2x = 13 (1)

5y + 4x = 24 (2)

Multiply (1) by 5 and (2) by 3 to eliminate y

15y + 10x = 65 (3)

15y + 12x = 72 (4)

Subtract (3) from (4)

12x - 10x = 72 - 65

2x = 7

x = 7/2

x = 3.5

Substitute x = 3.5 into (1)

3y + 2x = 13 (1)

3y + 2(3.5) = 13

3y + 7 = 13

3y = 13 - 7

3y = 6

y = 6/3

y = 2

Mass of brown egg = 3.5 grams

Mass of white egg = 2 grams

​ y=3x+3 y=−2x+3 ​ how many solutions does the system have

Answers

Answer: One solution

Step-by-step explanation:

y = 3x + 3

y = -2x + 3

-----------------------------------------------------------------------------------------------------------

To solve this, you need to understand a few things:

a) If two lines have the same slope but different y-intercepts, they are parallel when graphed and thus do not have any solutions

b) If two lines have the same slope and same y-intercepts, they are the same line when graphed and thus do not have infinitely many solutions

c) If two lines have different slopes (and/or y-intercepts), they have one solution

-----------------------------------------------------------------------------------------------------------

These two lines have different slopes but the same y-intercept (condition c)

So they have one solution

two numbers have ratio 12:5.their differnce is 49.find the two numbers .​

Answers

Answer:

84 and 35

Step-by-step explanation:

12 - 5 = 7

12(7) = 84

5(7) = 35

Two numbers: 84 and 35

Step-by-step explanation:

Let the two numbers be x and y

Given:

Ratio of two numbers= 12:5

Difference between two numbers= 49

So, we need to find the difference between its ratio in order to get two numbers.

12 - 5 = 7

Thus, simply on multiplying the number so obtained after subtraction we will get:  

12 * (7) = 84

5 * (7) = 35

Also, the difference is given which is 49

so, we can confirm it by finding the difference between the numbers obtained which is 84-35=49

Therefore, the two numbers are 84 and 35.

Answers

Answer:

x = 2.5

y = 5

Step-by-step explanation:

2x + 3y = 20

2x + y = 10 then y = 10 - 2x

substitute for y:

2x + 3(10 - 2x) = 20

2x + 30 - 6x = 20

reduce:

-4x = -10

divide both sides by -4:

x = 2.5

y = 10 - 2(2.5) = 5

check:

2(2.5) + 3(5) = 20

20 = 20

and

2(2.5) + 5 = 10

10 = 10

What is the degree measure of Angle P?

Answers

Answer:

D. 40°

Step-by-step explanation:

Angle formed by two secants is half of the difference of intercepted arcs:

m∠P = 1/2(mST - mQR)

Find the measure of missing arc:

mQR = 360° - (85° + 95° + 175°) = 5°

Substitute the value of arc QR into above equation:

m∠P = 1/2(85° - 5°) = 40°

Correct choice is D

Answers

Answer:

x = 12

Step-by-step explanation:

For trapezoid DEFG to be isosceles, measures of it's base angles must be equal.

i.e.

[tex] m\angle E =m\angle F[/tex]

[tex] (5x+15)\degree =(7x - 9)\degree [/tex]

5x + 15 = 7x - 9

5x - 7x = - 15 - 9

-2x = - 24

2x = 24

[tex] x = \frac{24}{2} [/tex]

x = 12

A = Pe^rt

(The rate must be in decimal form)
3.15% / 100 = .0315

1,512 = P[e^(.0315*12)]
1,512 / e^(.0315*12) = P
