Answer:

x>-2

Step-by-step explanation:

3(x + 4) > 4 - X

Distribute

3x+12> 4-x

Add x to each side

3x+12+x > 4-x+x

4x+12 > 4

Subtract 12 from each side

4x+12-12>4-12

4x> -8

Divide each side by 4

4x/4 > -8/4

x>-2

Answer:

x>-2

Step-by-step explanation:

3(x+4)>4-x

Do distributive property

3x+12>4-x

Add x on both sides

4x+ 12>4

Subtract 12 on both sides

4x>-8

Divide by 4 on both sides

x>-2

Factor completely 4x2 − 8x − 60. (4x − 20)(x + 3) 4(x − 5)(x + 3) (4x − 4)(x + 15) 4(x − 1)(x + 15)

katovenus [111]

after complete factorization of $4x^2-8x-60$ the answer is $4(x+3)(x-5)$

Step-by-step explanation:

We need to factor $4x^2-8x-60$

Taking 4 common and factorizing:

$=4(x^2-2x-15)\\=4(x^2+3x-5x-15)\\=4(x(x+3)-5(x+3))\\=4(x+3)(x-5)$

So, after complete factorization of $4x^2-8x-60$ the answer is $4(x+3)(x-5)$

A student solves a problem correctly 40 times out of 72 tries. Based on this data, what is the probability that the student inco

suter [353]

Answer:

The probability of the student incorrectly solves the next problem is 44%.

Step-by-step explanation:

Let E be the event of solving a problem correctly.

Then E' is the event that the problem is solved incorrectly.

Now, recall the definition of probability.

probability of an event = $\frac{number of favorable events}{total number of events}$

So,

p(E) = $\frac{40}{72}$

Also,

p(E) + p(E') = 1 and

p(E') = 1 - p(E)

= 1 - $\frac{40}{72}$

= $\frac{72-40}{72}$

= $\frac{32}{72}$

= $\frac{4}{9}$

= $\frac{4}{9} (100)$

= 44% rounded.

Hence, the probability of the student incorrectly solves the next problem is 44%.

A person walks 1/3 mile in 1/9 hour. At what speed is the person walking in miles per hour?

ki77a [65]

Speed (v) could be determined using this following formula
v = distance ÷ time

plug in the numbers
v = $\frac{1}{3} : \frac{1}{9}$
v = $\frac{1}{3} \times \frac{9}{1}$
v = 9/3
v = 3

The speed is 3 miles per hour

Korvikt [17]

Set 500 to sum of distances traveled by both cars.
$55t + 60t = 500 \\ 115t = 500 \\ t = (500/115) = 4.3$
