The value of x is 5/6 and y is 8/5.

Step-by-step explanation:

Given,

12x+15y=34   Eqn 1

-6x+5y=3   Eqn 2

Multiplying Eqn 2 by 2

2(-6x+5y=3)\\-12x+10y=6\ \ \ Eqn 3

Adding Eqn 1 and 3

(12x+15y)+(-12x+10y)=34+6\\12x+15y-12x+10y=40\\25y=40

Dividing both sides by 25

\frac{25y}{25}=\frac{40}{25}\\y=\frac{8}{5}

Putting y= 8/5 in Eqn 1

12x+15(\frac{8}{5})=34\\12x+3*8=34\\12x+24=34\\12x=34-24\\12x=10

Dividing both sides by 12

\frac{12x}{12}=\frac{10}{12}\\x=\frac{5}{6}

The value of x is 5/6 and y is 8/5.

What is a independent event
Andreas93 [3]

Step-by-step explanation: If two events are independent events, then the outcome of one event will not affect the outcome of the other event. I'll show an example.

Two coins are tossed. Find the probability of the following event.

P (heads and heads)

This problem would be dealing with independent events because the outcome of tossing 1 coin does not affect the outcome of tossing the second coin.

sergejj [24]

Answer:

The answer is below

Step-by-step explanation:

Mrs. Fielder decides to build a small snow shelter for her children to wait in before the school bus arrives in the morning. She has only enough wood for a total perimeter of 20 feet.

a. Make a table of all the whole number possibilities for the length and width of the shelter. Find the area of each shelter.

b. What dimensions should Mrs. Fielder choose to have the greatest area in her shelter?

c. What dimensions should Mrs. Fielder choose to have the least area in her shelter?

d. Township building codes require 3 square feet for each child in a snow shelter. Which shelter from part (a) will fit the most children? How many children is this? Explain your reasoning.

Solution:

a) Let W represent the width of the school shelter and let L represent the length of the school shelter. Therefore:

Perimeter of the school shelter = 2(length + breadth)

20 = 2(L + W)

L + W = 10

Also, the area of the school shelter = L * W

Length (ft)              Width (ft)           Area(ft²) = length * width

1                               9                        9

2                              8                        16

3                              7                         21

4                              6                         24

5                              5                         25

b) The shelter with a length of 5 ft and width of 5 ft has the largest area.            

c) The shelter with a length of 1 ft and width of 9 ft has the least area.  

d) The 4 by 6 ft shelter can hold 8 children (24 ft² / 3 ft² = 8) and the 5 by 5 ft shelter can hold 8 children with an extra space (25 ft² / 3 ft² = 8.33).

Paladinen [302]

Answer:

see in the picture, the perimeter of this rectangle is

2( x + 3x) = 8x but the perimeter is 65.6

=> 8x = 65.6

<=> x = 65.6/8

=> x = 8.2

Arada [10]

Answer:

The 20 pound bag is a better by for only $66.98

Step-by-step explanation:

The large bag is better because the small bag is $27.93 for 7 pounds 7x3=21,so 3x27.93=83.79 is $16.81 more than the cost for the large bag

hope this makes sense;)
