If 32x+1 -3x+5, what is the value of x?
kozerog [31]

Answer:

x=-0.21...

Step-by-step explanation:

Make the expression equal 0

32x+1-3x+5=0

Combine the x terms

29x+1+5=0

Combine the constants

29x+6=0

Isolate the x term

29x=-6

Isolate the variable

x=-0.21...

(I rounded to the nearest 100th)

Please help. I got the 12 part can’t can’t seem to simplify the fraction bit.
Sati [7]
<h3>Answer: D)  12 & 3/8</h3>

Whole part = 12

Fractional part = 3/8

==============================================

Explanation:

For now, let's just focus on the fractional parts of each mixed number.

We have these fractions:

  • 1/4
  • 4/16
  • 3/8
  • 1/2

The 4/16 reduces to 1/4, so 4/16 = 1/4

So in reality, we have these fractional parts.

  • 1/4
  • 1/4
  • 3/8
  • 1/2

It's not a typo that I'm listing "1/4" twice.

The next step is to get everything to have the same denominator. That denominator is 8 (aka the LCD)

  • 1/4 = 2/8
  • 1/4 = 2/8
  • 3/8 = 3/8
  • 1/2 = 4/8

Adding those new fractions gets us:

(2/8)+(2/8)+(3/8)+(4/8) = (2+2+3+4)/8 = 11/8

Rewrite that as a mixed number

11/8 = (8+3)/8

11/8 = (8/8) + (3/8)

11/8 = 1 + 3/8

11/8 = 1 & 3/8

We get the result 1 & 3/8, where 1 is the whole part and 3/8 is the fractional part.

Keep in mind that all we've done so far is add up the fractional parts. We were ignoring the whole parts from each original mixed number.

If we add the whole parts (3,2,1,5) we get 3+2+1+5 = 11, which adds onto the previous whole part of 1 to get 12. So that's where the 12 comes from.

The fractional part 3/8 comes along for the ride to get 12 & 3/8 as the final answer, which is choice D.

-----------------

An alternative route you can take is to convert each original mixed number into an improper fraction, then add those improper fractions (don't forget to get the LCD), and lastly convert the result to a mixed number.

According to the Centers for Disease Control, the probability that a randomly selected citizen of the United States has hearing
laila [671]
I think the answer is yes you can because they are both different things.

What I mean by that is that the United Stated as .151% of its people with hearing problems, and .093% with vision problems. So really adding them together just mixes it saying that .244% of people in the united states have either a vision or a hearing problem.

It doesn’t make it any more or any less people by adding them together. Therefore it’s not any more or any less probable to pick one or the other.

Hopes this helps.

12 (5x-1) = 7x (2x +2)
murzikaleks [220]
60x - 12 = 14x^2 + 14x

Subtract 60x & Combine

-12 = 14x^2+14x-60x
-12= 14x^2-46x
Add 12
0= 14x^2-46x-14
