The amount of workers varies inversely with the time, in days, to complete a project. Five workers can complete a certain projec

Feliz [49]

Answer:

Step-by-step explanation:

The number of days has gone down by a factor of 15/24. The number of workers is inversely proportional, so must increase by a factor of 24/15 = 8/5.

(5 workers) × (8/5) = 8 workers

8 workers are needed to complete the project in 15 days.

2 ( 4x - 3 ) - 8 = 4 + 2x Giving me a headache

Advocard [28]

1 Expand.

8x-6-8=4+2x8x−6−8=4+2x

2 Simplify 8x-6-88x−6−8 to 8x-148x−14.

8x-14=4+2x8x−14=4+2x

3 Add 1414 to both sides.

8x=4+2x+148x=4+2x+14

4 Simplify 4+2x+144+2x+14 to 2x+182x+18.

8x=2x+188x=2x+18

5 Subtract 2x2x from both sides.

8x-2x=188x−2x=18

6 Simplify 8x-2x8x−2x to 6x6x.

6x=186x=18

7 Divide both sides by 66.

x=\frac{18}{6}x=

8 Simplify \frac{18}{6}

to 33.

x=3x=3

A student solves the following equation and determines that the solution is −2. Is the student correct? Explain. 3 a + 2 − 6a a2

Ganezh [65]

For this case, we have the following equation (according to the comments):

$\frac{3}{a+2} - \frac{6a}{a^2-4} = \frac{1}{a-2}$

First, we factor the quadratic expression in the denominator:

$\frac{3}{a+2} - \frac{6a}{(a-2)(a+2)} = \frac{1}{a-2}$

Then, we multiply both sides of the equation by (a-2) (a + 2):

$\frac{3(a-2)(a+2)}{a+2} - \frac{6a(a-2)(a+2)}{(a-2)(a+2)} = \frac{(a-2)(a+2)}{a-2}$

Later, canceling similar terms we have:

$3(a-2) - 6a = a+2$

We do distributive property on the left side of the equation:

$3a-6-6a=a+2$

By grouping variables and constant terms we have:

$3a - 6a -a = 2+6$

Rewriting we have:

$-4a=8$

Finally, by clearing "a" we have:

$a=-\frac{8}{4} a=-2$

Note: the value of a is a extraneous solution because it makes the denominator of the original equation equal to zero.

Answer:

the student correct, but the value of a= -2 is an extraneous solution
