What is the solution to the equation below?
2(x - 3) = 2x + 5
A
3
X = 2
B
X=-2
= -2
A10
С
There is no solution.
D
There are infinitely many solutions.
Answer:
C. There is no solution.
Step-by-step explanation:
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.

Help me with this question ASAP please
Answer:
1) 14°
2)117°
3) 78°
4) 66°
5) 64°
6) 28°
7)35°
8) 48°
Step-by-step explanation:
just subtract both angles from 180 because all triangle's angles always add up to 180°
1. ) 14
2.) 117
3.) 78
4.) 66
5.) 64
6.) 34
7.) 45
8.) 48
the person before me i dont think dod did their math right bc some of their math answers are wrong on 5 through 8 i think it is.
NOW HERE'S HOW TO DO IT WITH EXAMPLES OF YOUR QUESTIONS
in triangles all angles added up cant be more than 180 degrees . basically you take 180 and subtract the known angles and what is left over is the unknown angle
example question 1.) 180-112-54=14
question 2.) 180-38-25=117. i hope this helps. man i should have typed faster id be first. owell goodluck

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.
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

CAN U GIMME BRAIN PLZ!Find the measure of interior angle C of hexagon OCEANS in which the
measure of the interior angles are:
O: 3x + 15, C: 2x + 30, E: 5x + 10, A: 2x + 55, N: 2x + 60, and S: x - 35.
Answer:
The measure of the interior angle C is [tex]108^{o}[/tex].
Step-by-step explanation:
Sum of angles in a polygon = (n - 2) x 180
where n is the number of sides of the polygon.
For a hexagon, n = 6. So that;
Sum of angles in a hexagon = (6 - 2) x 180
= 4 x 180
= [tex]720^{o}[/tex]
Sum of angles in a hexagon = [tex]720^{o}[/tex]
⇒ 3x + 15 + 2x + 30 + 5x + 10 + 2x + 55 + 2x + 60 + x - 35 = [tex]720^{o}[/tex]
15x + 135 = [tex]720^{o}[/tex]
15x = [tex]720^{o}[/tex] - 135
15x = 585
x = [tex]\frac{585}{15}[/tex]
= [tex]39^{o}[/tex]
But,
C = 2x + 30
= 2(39) + 30
= 78 + 30
= [tex]108^{o}[/tex]
The measure of the interior angle C is [tex]108^{o}[/tex].
Can someone please help me
I have no clue how to do these, if you could answer one with an explanation that would be amazing
Answer:
2. I assume you're working on 1 so I skipped it. 2 would be 16000 yearly. 300 a week would equal 15,000 a year so its less
There are 52 weeks in a year which is how I got that number^
3. With the job he has he gets 21,548.8 per year(11.20 × 37 = 414.4 x 52 = 21,548.8). With the advertised job he would would get 21,150 yearly. 21000 + 5% of 3000 which would be his commission. so stick with his current job
4. (£9.40 x 35 hours = £329) (£329 x 52 weeks = £17,108). (3 extra hours per week x 52 weeks = £156) (£17,108 + £156 = £17,264) That is her total
I need help on knowing whether this is a solvable equation. Along with reasons why. HELP IF YOU CAN :))
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.

Mr. Marquez discovered that 18 of his 24 students enjoy reading in their spare time. What percent of his students enjoy reading in their spare time?
Answer:
75%
Step-by-step explanation:
Use 'Percent(age) Composition'
1. (18/24) = 0.75 This shows that 0.75/1 students reads during their free time.
2. 0.75 x (100) = 75% This step is to allow the value we received above to be displayed as a percentage.
75% of students enjoy reading in their spare time.

To answer this question, you need trigonometry.
Are you familiar with the chant soh cah toa?
In here, you can see that the side you have is adjacent to the angle you have, and you're trying to find the opposite side. This means you need tangent = opposite ÷ adjacent
If the angle was 30° 45° or 60° Then there is a table you can use to calculate, but there isn't so just use a calculator
tan 31° = x ÷ 10
