Xy = 450

y = x/2 => x=2y  substituted inside first equation will get 2y*y=450 => y^2 = 225

y=15 because 15*15=225

x=2y so x=2*15 = 30 

x=30
y=15

hope this will help you

Answer:

\frac{1}{2}y\cdot y=450

Step-by-step explanation:

Let x represent 1st number and y represent 2nd number.

We have been given that the product of two numbers is 450. We can represent this information in an equation as:

x\cdot y=450...(1)

We are also told that the first number is half the second number. We can represent this information in an equation as:

x=\frac{1}{2}y...(2)

To solve for greater number ,y, we will substitute equation (2) in equation (1) as:

\frac{1}{2}y\cdot y=450

Therefore, our required equation would be \frac{1}{2}y\cdot y=450.

An actor gained 20 pounds for a part and then loses 15 pounds during the filming of the movie to go along with the story describ
Tom [10]

We are given statement " gained 20 pounds and loses 15 pounds".

<em>Note: We take plus or positive sign for gain word and we take minus or negative sign for the loses word.</em>

Gained 20 means +20.

Loses 15 mean -15.

Therefore, we can setup an expression as:

<h3>+20 -15.</h3>

20 is a positive number and 15 is a negative number.

Because we have opposite signs of numbers, we would subtract them.

20-15 = 5 pounds.

grin007 [14]

Answer:

a. x < 55

Step-by-step explanation:

We know that the temperature in November was less than 55° every single day, we are then asked to find which inequality out of the four given shows the temperature in November.

To do so, take the most crucial information, "the temperature in November was less than 55° every single day." The words "less than" makes us know that we will be using the sign "<". Looking at the answers, we see only one that uses it, and that is a.

Therefore a is the correct answer.
