The mean amount of water in 5 containers is 620 ml the total amount of water in 4 q of the containers is 2750 what is the amount
EleoNora [17]
<span>The <u>correct answer</u> is:

350 ml.

Explanation<span>:

Let x be the amount in the fifth container.

The mean is found by adding all of the amounts together and dividing by the number of containers (in this problem, 5). We know that the total from the other 4 containers is 2750; add this to x, our unknown number. Then we divide by 5 to arrive at our answer of 620.

Algebraically,
</span></span>\frac{2750+x}{5}=620<span><span>

To solve, multiply both sides by 5:
</span></span>\frac{2750+x}{5}\times 5=620\times 5&#10;\\&#10;\\2750+x=3100<span><span>

Subtract 2750 from both sides:
 2750+x-2750=3100-2750
x=350.

There are 350 ml in the fifth container.</span></span>

Type the correct answer in each box. Round numbers to the nearest tenth, if necessary.
nexus9112 [7]

ANSWER

x = 1.6

EXPLANATION

The given equation is:

- 0.5x - 2 = 2x - 1 - 6

Group similar terms to obtain:

- 0.5x - 2x =  - 5 - 1 + 2

Simplify similar terms,

- 2.5x =  - 4

Divide both sides by -2.5

x =  \frac{ - 4}{ - 2.5}

x = 1.6
