<h3><u>The value of y is 1.6</u></h3><h3><u>The value of x is 4.5</u></h3>

By elimination:

2x + 5y = 17

6x - 5y = 19

<em><u>We can add the second equation to the first in order to isolate one variable.</u></em>

(2x + 5y) + (6x - 5y)

8x = 17

<em><u>Because we added the left side, we have to add the right side here as well.</u></em>

17 + 19 = 36

8x = 36

<em><u>Divide both sides by 8</u></em>

x = 4.5

We can plug this value back into the original equation to find the value of y.

2(4.5) + 5y = 17

9 + 5y = 17

<em><u>Subtract 9 from both sides.</u></em>

5y = 8

<em><u>Divide both sides by 5.</u></em>

y = 1.6

Bess [88]

Answer:

$37,500

Step-by-step explanation:

We have been given that a house worth $180,000 has a coinsurance clause of 75 percent. The owners insure the property for $101,250. They then have a loss that results in a $50,000 claim.

We will use loss settlement formula to solve our given problem.

\text{Loss settlement}=\frac{\text{Loss}\times\text{Limit of insurance}}{\text{Actual cash value}\times \text{Coinsurance}\%}

Upon substituting our given values, we will get:

\text{Loss settlement}=\frac{\$50,000\times\$101,250}{\$180,000\times 75\%}

\text{Loss settlement}=\frac{\$50,000\times\$101,250}{\$180,000\times 0.75}

\text{Loss settlement}=\frac{\$5,062,500,000}{\$135,000}

\text{Loss settlement}=\$37,500

Therefore, they will receive $37,500 from insurance.

Find the ratio in which y-axis divides the line segment joining the points A(5, -6), and B (-1, -4). Also find the coordinates o
lora16 [44]

Answer:

Something like this

Step-by-step explanation:

distance √(-1 - 5)² + (-6 - -4)² = √36 + 4 = √40 = 6.32

slope = 2/-6 = -1/3

distance (-1,-4) to (0, -4.63)

√(-1 - 0)² + (-4 - -4.63...)² = √1.4 = 1.18

6.32 - 1.18 = 5.14

1.18 : 5.14

How long does it take for a car traveling at a speed of 50.0 miles per hour to travel 300 feet?
beks73 [17]
We know, Time = distance / speed
t = 0.0568182 / 50  [ 300 Feet = 0.0568182 miles ]
t = 0.001136 * 3600 s
t = 4.09 sec

In short, Your Answer would be 4.09 Seconds

Hope this helps!
