The weight in kilograms of an object that weighs 70 pounds is 31.5 kilograms.

<h3>How to calculate the value?</h3>

Given that the number of kilograms that an object weighs varies directly with the number of pounds and that an object weighs 45 kilograms weighs 100 pounds.

This will be:

y = mx

y = weight in kilograms

x = weight in pounds

k = constant

45 = 100k

Divide

k = 45/100

k = 0.45

The equation will be written as y = 0.45x

Therefore, when the object weighs 70 pounds, this will be:

y = kx

y = 0.45 × 70

y = 31.5

The weight in kilograms is 31.5kg

Evaluate the following expression for x= 3 , y = 2, and z=2 the expression is 5y(7z-x)

5y(7z - x)

There is another way to do this, I believe, but unless I find a mistake, this is my answer. You just have to insert the value of the variables.

Owners of a recreation area are filling a small pond with water. Let y represent the total amount of water in the pond (in liter
devlian [24]

Answer:

  1. 32
  2. 400

Step-by-step explanation:

Lets start by defining the numbers in the equation.

This  equation is in slope-intercept form meaning that it is y=mx+b or y = b+mx they are both the same

In slope-intercept form,

  • m = slope or rate
  • and b = y-intercept

Th equation is y=400+32x so now we know

  • b=400
  • and m=32

For the first question the change per minute is the rate so it is <u>32.</u>

For the second question the starting amount is the same as the y-intercept so it is <u>400.</u>
