First, multiply what in the parentheses by what's outside of them.
[tex]2(x - 3) = 2x + 5 ↴[/tex]
[tex]2x - 6 = 2x + 5 [/tex]
Then seperate variables from nonvariables. After subtracting [tex]2x[/tex] from the right and left side, the equation becomes this:
[tex] - 6 = 5[/tex]
This equation has no solutions because this is an inequality.

To check if x = 9 is the solution, we need to replace every x with 9 and simplify
(3+x)/4 = 3
(3+9)/4 = 3
12/4 = 3
3 = 3
We get the same thing on both sides, so the last equation is a true equation. This means that the first equation is a true equation when x = 9. Therefore, the solution x = 9 is confirmed.

An object is traveling at a steady speed of 9 9/10 km/per hour about how long will it take the object to travel 5/1/10 km/per hour.
Answers
Answer:
0.52 km
Step-by-step explanation:
We are given that
Speed of object, v=[tex]9\frac{9}{10}km/h[/tex]
Speed of object, v=[tex]9+0.9=9.9km/h[/tex]
Distance travel by object, s=[tex]5\frac{1}{10}km[/tex]
Distance travel by object, s=[tex]5+0.1=5.1km[/tex]
We have to find the time taken by object to travel 5 1/10 km.
We know that
[tex]Time=\frac{Distance}{speed}[/tex]
Using the formula
Time taken by object to travel 5.1 km =[tex]\frac{5.1}{9.9} hr[/tex]
Time taken by object to travel 5.1 km=0.52 hr

Step-by-step explanation:
See comment for correct presentation of the question
Given
[tex]Expression = 40\% * 75[/tex]
[tex]Priya = \frac{2}{5} * 75[/tex]
Required
Is Priya correct?
We start by simplifying the expression.
[tex]Expression = 40\% * 75[/tex]
Express 40% as fraction
[tex]Expression = \frac{40}{100} * 75[/tex]
Simplify fraction: Divide numerator and denominator by 20
[tex]Expression = \frac{40/20}{100/20} * 75[/tex]
[tex]Expression = \frac{2}{5} * 75[/tex]
By comparing:
[tex]Expression = \frac{2}{5} * 75[/tex]
and
[tex]Priya = \frac{2}{5} * 75[/tex]
We can conclude that Priya is correct because:
[tex]40\% = \frac{2}{5}[/tex]

Step-by-step explanation:
Using Trigonometry,
tan33° = Opposite/Adjacent = GF/DF.
Therefore GF = DF * tan33°
= 235tan33° = 152.6.
Angle GEF = Angle EDG + Angle DGE
= 33° + 34° = 67°. (Exterior Angle Theorem)
Using Trigonometry,
sin67° = Opposite/Hypotenuse = GF/EF.
Therefore EF = GF / sin67°
= 152.6 / sin67° = 165.8.
Hence the answer is the 1st option.
Answer:
the answer is A. GF =152.6 and EG=165.8
GF= 235*(tan(33))
EG= 152.6/(sin(67))

Answer:
Multiply the second equation by 2
Solution: [tex](-\frac{45}{11},\frac{29}{11})[/tex]
Step-by-step explanation:
1) In order to use the elimination method to solve systems of equations, you must first multiply one or both of the equations so that the coefficients of a pair of terms with matching variables share the same number, but have opposite signs.
In this case, the y terms must fit that requirement. The y term in the first equation is 2y and the one in the second equation is -y. They already have opposite signs, one positive and other negative, so we just need -y to be -2y. So, in order to do that, multiply by 2.
2) After multiplying the whole second equation by 2, you will get [tex]8x - 2y = -38[/tex]. Now, add the the two equations together, eliminate the y terms, and isolate x to find its value.
3) Then, substitute that x value back into one of the equations to receive the y-value.
To better explain these steps, I attached pictures below.

A forest covers 52000 acres. A survey finds that 0.4% of the forest is old-growth trees. How many acres of old-growth trees are there?
Answers
Given:
Total forest area = 52000 acres
Area of old growth trees in the forest = 0.4%
To find:
The area of old growth trees.
Solution:
We have,
Total forest area = 52000 acres
Area of old growth trees in the forest = 0.4%
Area of old growth trees is
[tex]Area=0.4\% \text{ of total forest area}[/tex]
[tex]Area=\dfrac{0.4}{100}\times 52000[/tex]
[tex]Area=0.4\times 520[/tex]
[tex]Area=208[/tex]
Therefore, the area of old growth trees is 208 acres.

This is by far the easiest question ever...Can you actually read and put effort into it before looking up all your answers next time? It literally says there are 16 CATS and 14 DOGS in a SHELTER. Its not A, because it did not mention rabbits. Its not C because it did not mention too much about cats, and it said dogs and cats not cats and cats. And its not D because we aint talking about a neighborhood. So..it is B. Easy, peasy, lemon squeezy!
