Kate is 17 years old, and Victor is 12 years younger. In how many years will Kate be twice as old as Victor?

9966 [12]

Answer:

In 7 years

Step-by-step explanation:

Let

n ----> the number of years

x -----> Kate's age

y ----> Victor's age

we know that

$(x+n)=2(y+n)$

we have

$x=17\\y=17-12=5\\$

Victor's age is 5

substitute the given values

$(17+n)=2(5+n)$

Solve for n

$17+n=10+2n$

$2n-n=17-10$

$n=7$

<u><em>Verify</em></u>

In 7 years

Kate's age is 17+7=24

Victor's age is 5+7=12

24=2(12)

so

Kate is twice as old as Victor

Mariulka [41]

Answer:

Step-by-step explanation:

Triangle ABC: 30^2 + 40^2 = 50^2 is a true statement, so by the Pythagorean theorem, this is a right triangle.

Triangle XYZ: 1^2 + 1^2 = 2^2 is a false statement, so by the Pythagorean theorem, this is not a right triangle.

Triangle EFG: 8^2 + 15^2 = 17^2 is a true statement, so by the Pythagorean theorem, this is a right triangle.

The heat in the house is set to keep the minimum and maximum temperatures (in degrees Fahrenheit) according to the equation |x –

solniwko [45]

Answer:

Minimum temperature is 68.5 ° and maximum temperature is 76.5 °

Step-by-step explanation:

Given :

|x – 72.5| = 4.

When the Temperature of x is minimum So the Minimum temperature is

$|x - 72.5| = 4\\it\ can \ be \ written \ as \\72.5-x=4\\-x=4-72.5\\x=68.5$

When the Temperature of x is maximum So the Maximum Temperature is

$|x -72.5| = 4\\x-72.5=\ 4\\x=72.5+4\\x=76.5$

Therefore The minimum temperature is 68.5 ° and the maximum temperature is 76.5 °
