Consider triangle GHJ.

bulgar [2K]

we know that

Applying the Pythagorean Theorem

$JG^{2} =HJ^{2}+HG^{2}$

solve for HJ

$HJ^{2}=JG^{2}-HG^{2}$

in this problem we have

$JG=10\ units\\ HG= 5\ units$

Substitute the values in the formula above

$HJ^{2}=10^{2}-5^{2}$

$HJ^{2}=100-25$

$HJ^{2}=75$

$HJ=\sqrt{75}=5\sqrt{3} \ units$

therefore

the answer is the option

Complete the table. Original Price- $ Percent of Discount- 5% Sale Price- $57

astra-53 [7]

The original price is $ 60

Solution:

Given information are:

Original price = ?

Percent of discount = 5 %

Sales price = $ 57

So, we have to find out the original price

Let "x" be the original price

Then, we can say,

Original price = sales price + discount percent of original price

x = 57 + 5 % of x

$x = 57 + 5 \% \times x\\\\x = 57 + \frac{5}{100} \times x\\\\x = 57 + 0.05 \times x\\\\x = 57 + 0.05x\\\\x - 0.05x = 57\\\\0.95x = 57\\\\Divide\ both\ sides\ of\ equation\ by\ 0.95\\\\x = 60$

Thus original price is $ 60

2x-4y=8

x+2y=4 /*2

2x-4y=8

2x+4y=8 (+)

4x=16

x=4

4+2y=4

y=0

(x;y)={(4; 0)}

Exactly one solution.
