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

Q16. Find x^2 + 1/x^2 , if x + 1/x = 3
Answer:
[tex] 2 \times x \times \frac{1}{x} = 2 \\ {x}^{2} + {y }^{2} + 2xy = {(x + y)}^{2} \\ {x}^{2} + \frac{1}{ {x}^{2} } + 2 = {(x + \frac{1}{x} })^{2} = {3}^{2} = 9[/tex]

Answer:
B
Step-by-step explanation:
|15-12|/4 = 3/4
|(-21+9)/8| = |-12/8| = 12/8 = 3/2 (Simply)
3/4 - 3/2 = -3/4
So the answer is B.

x² - 9 / х^2 - 3x
Answer:
[tex]\frac{x+3}{x}[/tex]
Step-by-step explanation:
Factorise numerator and denominator
x² - 9 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
x² - 9
= x² - 3² = (x - 3)(x + 3)
x² - 3x ← factor out x from each term
= x(x - 3)
Then
[tex]\frac{x^2-9}{x^2-3x}[/tex]
= [tex]\frac{(x-3)(x+3)}{x(x-3)}[/tex] ← cancel common factor (x - 3) on numerator/denominator
= [tex]\frac{x+3}{x}[/tex]

23.) Find the total surface area
Answer:
252 m
Step-by-step explanation:
Triangles: (base x height) 2
Rectangles: width x length
Triangles = 2(7*6)/2 = 42 m
Rectangles = 3(7*10) = 210
210 + 42 = 253 m
solve for x pleaseeee
Answer:
D
Step-by-step explanation:
15^2 = 15 x 15 = 225
12^2 = 12 x 12 = 144
144 + 225 = 369
369 squared = 19.2

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!
