Write an absolute value inequality and a compound inequality for each length x with the given tolerance.
BabaBlast [244]
<span>The absolute value inequality of a length of 36.80 mm with a tolerance of 0.05 mm</span> is given by |x - 36.80| < 0.05
and
The compound inequality of a length of 36.80 mm with a tolerance of 0.05 mm is obtained as follows:
|x - 36.80| < 0.05
-0.05 < x - 36.80 < 0.05
-0.05 + 36.80 < x < 0.05 + 36.80
36.75 < x < 36.85.

A greedy hamster hoarded 2 piles of sunflower seeds. Yesterday the ratio of the seeds in these piles 3:4; but today the greedy h
Airida [17]

The weight of each pile yesterday will be 6 and 8 pounds.

<h3>What is the unitary method?</h3>

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

It is Given that Yesterday the ratio of seeds in these piles was 3:4.

Let 3x and 4x represent the seeds.

If the 2 pounds of seeds are added in the bigger pile, then

4x + 2

He also ate 1/4 pound from the smaller pile,

3x - 1/4

The quantities of seeds in those piles is in the ratio of 5:16.

So, 4x + 2 = 5x

3x - 1/4 = 16x

Solve;

So, 4x + 2 = 5x

2 = 5x - 4x

x = 2

The weight of each pie will be

3x = 6 pound

4x = 8 pound

Hence, The weight of each pile yesterday would be 6 and 8 pounds.

Which of the following is a solution of x² - 7x = -5?
lesya [120]

\frac{7 -  \sqrt{} 29} {2}

x {}^{2}  - 7x =  - 5 \\ x {}^{2}  - 7x - ( - 5) =  - 5 - ( - 5) \\ x {}^{2}  - 7x( - 5) = 0 \\ x {}^{2}  - 7x + 5 = 0 \\ x =  \frac{ - ( - 7 +  \sqrt{( - 7 {) }^{2}  - 4 \times 5} }{2}  \\ x  =  \frac{ - ( - 7 +  \sqrt{49 - 4 \times 5} }{2}  \\ x =  \frac{ - ( - 7) +  \sqrt{49 \times 20} }{2}  \\ x =  \frac{ - ( - 7) \sqrt{29} }{2}  \\ x =   \frac{7 +  \sqrt{29} }{2}  \\  \frac{ \sqrt{29 + 7} }{2}  \\ x =  \frac{7 -  \sqrt{29} }{2}  \\ x =   \frac{ \sqrt{29 + 7} }{2}  \\ x =  \frac{7 -  \sqrt{29} }{2}
