let’s create a word problem using the factors 9 and 10.
=> Maria bought 9 couple shirts and the price of each pairs of couple shirt
is 10 dollar. Now, find the total amount that Maria spent for the 9 couple
shirt that she bought.
Now, let’s show the solution to our given word problem
=> Number of pairs of couple shirt = 9
=> Amount of each pairs of couple shirt = 10 dollars
=> 9 x 10
=> 90
Thus Maria paid 90 dollars in total.</span><span>

Volume of a Cone Formula:
- <em>r</em> is radius
- <em>h</em> is height
Step-by-step explanation:
<u>Step 1: Define</u>
Radius <em>r</em> = 4
Height <em>h</em> = 21
<u>Step 2: Find Volume</u>
- Substitute in variables [Volume of a Cone Formula]:

The value of x is 13°.
Solution:
<em>In triangle, sum of all the interior angles = 180°</em>
m∠A + m∠B + m∠C = 180°
(3x)° + (4x – 1)° + 90° = 180°
3x° + 4x° – 1° + 90° = 180°
7x° + 89° = 180°
Subtract 89° from both sides of the equation, we get
7x° = 91°
Divide by 7 from both sides of the equation, we get
x° = 13°
The value of x is 13°.
Answer:
s = -4.5
Step-by-step explanation:
14s + 10 = 6s - 26
Subtract 6s from each side
14s -6s +10 = 6s -6s -26
8s +10 = -26
Subtract 10 from each side
8s +10-10 = -26 -10
8s = -36
Divide by 8
8s/8s = -36/8
s = -36/8
Divide the top and bottom by 4
s = -9/2
s = -4.5
