<h3><u>The unknown number is equal to 4.</u></h3>
8x - 27 = 5
Add 27 to both sides.
8x = 32
Divide both sides by 8
x = 4
Answer:
Last option: 
Step-by-step explanation:
If the shell of a bass drum was cut down one side and laid flat, the resulting shape would be a rectangle.
The area of a rectangle can be calculated with the formula:

Where l is the lenght and w is the width.
In this case, the lenght of the rectangle obtained (the lenght of the shell) is the circumference of the drum.
Remember that the circumference of the circle can be calculated with:

Where r is the radius of the circle.
Then:

The width is the height of the shell:

Then, substituting into
, you get:

Answer:
y = 4
Step-by-step explanation:
(2/3 + 4) + (-3/2y + 1/3y) = 0
(-3/2y + 1/3y) = -4 2/3
-9/6y + 2/6y = -14/3
-7/6y = -14/3
cross-multiply:
-21y = -84
y = 4
Given:
Elena has a pet parakeet that weighs 6 when measured in one unit and 170 when measured in a different unit.
6__________ = 170______
To find:
The correct units from grams and ounces for these blanks.
Solution:
We know that, 1 ounce is greater than 1 gram.
1 ounce = 28.3495 grams
Multiply both sides by 6.
6 ounces = 170.097 grams
Approximate the values to the nearest whole number.
6 ounces = 170 grams
Therefore, 6 ounces = 170 grams.
