Answer:
Step 1 : <u>1000</u> * 2 * 9
Step 2 : <u>1000</u> * 18
Step 3 : <u>18000</u>
Step-by-step explanation:
<u>Step 3</u>
2000 * 9 = y ⇒ 18000
y = <u>18000</u>
<u>Step 1</u>
Solving for this, we have:
Let a be the unknown variable
a * 2 * 9 = 18000
18a = 18000
a = <u>1000</u>
Therefore, when we multiply 1000 by 2 & 9, we have 18000
<u>Step 2</u>
Solving for this, we have:
Let a be the unknown variable
a * 18 = 18000
18a = 18000
a = <u>1000 </u>
Therefore, when we multiply 1000 by 18, we have 18000
<u>We therefore see that the value of the unknown variables (a, y) is shown above & the product of all the steps (step 1 - 3) is 18000</u>
Answer:
<h3>The possibilities of length and width of the rectangle are </h3><h3>x=1, y=0.24;</h3><h3>x=0.5, y=0.48;</h3><h3>x=0.25, y=0.96;</h3><h3>x=2, y=0.12</h3>
Step-by-step explanation:
Given that the area is 0.24 square meter
The area of a rectangle is given by
square units
Let x be the length and y be the width.
Since the area is 0.24 square meter, we have the equation:
, with x and y measures in meters
If we want to know some possibilities of x and y, we can assume a value for one of them, and then calculate the other one using the equation.
Now choosing some values for "x", we have:
Put x = 1

∴ y = 0.24
Now put x = 0.5 we get
∴ y = 0.48
Put x = 0.25
∴ y = 0.96
Put x = 2

∴ y = 0.12
Hello! So in order to solve this problem, it's best to start off making an equation. $18 + $.15x = $29.25
In this equation x represents the number of minutes she used. So now, we just have to solve for x.
First subtract $18 from both sides. Your new equation will be $.15x = $11.25. Then divide both sides by $.15 to get x by itself. $11.25/$.15 = 75.
So we can conclude that Bella spoke on the phone for 75 minutes this last month. Hope this helps!
