The price of 600 grams of candy and 1.5 kg of cookies was 4 dollars and 62 cents. What is the price of one kg of cookies if it i

cupoosta [38]

Answer:

The price of the kilogram of cookies is $ 1.8

Step-by-step explanation:

Call x the price of the kilogram of candy and call y the price of kilogram of cookies

Then we know that

$0.600x + 1.5y = 4.62$

We also know that the price of kilogram of cookies is 1.40 dollars cheaper than the kilogram of candy

$y = x-1.40$

We solve this equation for x and then we substitute it in the first equation.

$x = y + 1.40$

$0.60 (y +1.40) + 1.5y = 4.62\\\\0.60y + 1.5y = 4.62 - 0.84\\\\2.1y = 3.78$

$y = \$1.8$

Answer:

y = 5 ft

Step-by-step explanation:

We are looking for y.

This is a right triangle, so we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

a = 12 and b = y c = 13

12^2 + y^2 = 13^2

144 + y^2 =169

Subtract 144 from each side

144-144 +y^2 = 169-144

y^2 = 25

Take the square root of each side

sqrt(y^2) = sqrt(25)

y = 5
