The price of 10 citrons and 7 fragrant wood apples is 55 units. The price of 7 citrons and 10 fragrant wood apples is 64 units.

a_sh-v [17]

Price of one citron = 5 units

Price of one fragrant = 5/7 units = 0.71 units

Further explanation:

Let x be the price of one citron and

y be the price of one fragrant

Then according to given statement

10x+7y = 55 Eqn 1

7x+10y = 64 Eqn 2

Multiplying equation 1 by 7

$7(10x+7y) = 7(55)\\70x+49y=385$

This will be equation 3.

Multiplying equation 2 by 10

$10(7x+10y) = 10(64)\\70x+100y=640$

This will be equation 4.

Subtracting equation 3 from equation 4

$70x+100y - (70x+49y) = 640-385\\70x+100y-70y-49y = 255\\51y = 255\\\frac{51x}{51} = \frac{255}{51}\\x = 5\\Putting\ x=5\ in\ equation\ 1\\10(5)+7y = 55\\50+7y = 55\\7y = 55-50\\7y = 5\\\frac{7y}{7} =\frac{5}{7}$

So,

Price of one citron = 5 units

Price of one fragrant = 5/7 units = 0.71 units

What is the answer to the equation x squared minus 2x equals 15.

anzhelika [568]

Answer:

$x = 5 \\ x = - 3$

Step-by-step explanation:

${x}^{2} - 2x = 15 \\ {x}^{2} - 2x - 15 = 0 \\ {x}^{2} + 3x - 5x - 15 = 0 \\ x(x + 3) - 5(x + 3) = 0 \\ (x - 5)(x + 3) = 0 \\ x - 5 = 0 \: \: \: \: \: or \: \: \: \: x + 3 = 0 \\ x = 5 \: \: \: \: or \: \: \: \: \: \: x = - 3$
