3+x=2–3x how many solutions and the answer thank you

Answers

Answer:

[tex]1[/tex] solution

Step-by-step explanation:

Let's try to solve this and see where we get.

We can add 3x to both sides of the equation to get [tex]3+4x=2[/tex].

We can then subtract 3 from both sides of the equation to get [tex]4x=-1[/tex].

We lastly divide both sides of the equation by 4 to get [tex]x=-1/4[/tex].

Because all of our steps are reversible(for instance, when we divide by 4, we can multiply(the "reverse" of division) by 4, so dividing by 4 is reversible), there is only [tex]\boxed{1}[/tex] solution, [tex]x=-1/4[/tex].

in a sale, the normal price of a hat is reduced by 15%
The sale price of the hat is 20.40 euros.
Work out the normal price of the hat.

Answers

Answer:

The correct answer is 24

Step-by-step explanation:

To solve this math problem, you will need to divide 20.40 with 1 (1 is 100% as a decimal) and 0.15 (0.15 is 15% as a decimal).

--

[tex]20.40[/tex] ÷ [tex](1-0.15)[/tex]

--

First, subtract 1 and 0.15

[tex]1-0.15=0.85[/tex]

Next, divide 20.40 and 0.85

[tex]20.40[/tex] ÷ [tex]0.85 = 24[/tex]

--

Therefore, the final product of this math problem is 24

100 POINTS AND BRAINLIEST!!

Answers

Possible Answer: B) $1,585.70

Explanation:
15% of $2,200 = $330

7.65% of $2,200 = $168.3

3% of $2,200 = $66

$330 + $168.3 + $66 = $564.3

$564.3 + $50 (healthcare cost) = $6.14.3

$2,200 - $614.3 = $1585.70

Answer:

$1,585.70

Step-by-step explanation:

15% of $2,200 = $330

7.65% of $2,200 = $168.3

3% of $2,200 = $66

$330 + $168.3 + $66 = $564.3

$564.3 + $50 (healthcare cost) = $6.14.3

$2,200 $614.3 = $1585.70

Answer:

[tex]3781/9000[/tex]

Step-by-step explanation:

[tex]0.42\overline{1}=42/100+0.00\overline{1}[/tex].

Recall that [tex]0.\overline{1}=1/9[/tex].

So, we want [tex]42/100+1/9*1/1000[/tex].

This simplifies to [tex]21/50+1/9000[/tex].

We know that [tex]21/50=(21*180)/(50*180)=3780/9000[/tex].

So, our expression is [tex]3780/9000+1/9000=3781/9000[/tex], which can't be simplified more.

So, our answer is [tex]\boxed{3781/9000}[/tex] and we're done!
