6.447
Step-by-step explanation:
He bought 264.10 / 6.95 = 38 bags.
Every bag covers 245 / 38 = 6.447 square feet.
Answer:
x = -27
Step-by-step explanation:
Simplifying
5(x + 3) = 4(x + -3)
Reorder the terms:
5(3 + x) = 4(x + -3)
(3 * 5 + x * 5) = 4(x + -3)
(15 + 5x) = 4(x + -3)
Reorder the terms:
15 + 5x = 4(-3 + x)
15 + 5x = (-3 * 4 + x * 4)
15 + 5x = (-12 + 4x)
Solving
15 + 5x = -12 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
15 + 5x + -4x = -12 + 4x + -4x
Combine like terms: 5x + -4x = 1x
15 + 1x = -12 + 4x + -4x
Combine like terms: 4x + -4x = 0
15 + 1x = -12 + 0
15 + 1x = -12
Add '-15' to each side of the equation.
15 + -15 + 1x = -12 + -15
Combine like terms: 15 + -15 = 0
0 + 1x = -12 + -15
1x = -12 + -15
Combine like terms: -12 + -15 = -27
1x = -27
Divide each side by '1'.

Step-by-step explanation:
<u>Angles and Lines</u>
The figure shows two triangles WXZ and WYZ. Considering:
* Angles WXZ and WYZ are right (90°)
* Sides XW and YW are congruent (red marker on both)
* They share the side WZ.
We can conclude they are congruent. Thus, angles XZW and YZW are congruent or have the same measure:
5x + 4 = 6x
Subtracting 5x:
4 = x
Or, x =4
Thus:

Answer:
The answer is - sample.
Step-by-step explanation:
Based on the set of 356 surveys that were completed and returned, the researcher finds that these students spend an average of 3.1 hours each day watching television.
For this study, the set of 356 students who returned the surveys is an example of a SAMPLE.
A sample is defined as a small part that shows what the whole population is like.
