x = 21
Answer:
x= -0.5
Step-by-step explanation:
You want to isolate x on one side of the equation
15-12x=21
-15 -15
-12x=6
/-12 /-12
x= -0.5
6th one....pls help me out
Now , For 12n to end with 0, it should have 2 as well as 5 in its Prime factors to end with 0, Also to end with 5 , it requires at least a single multiple of 5 in its Prime Factors, So 12n cannot end with the digit 0 or 5.
Any suggestions for concentrating on schoolwork?
Don't answer unless you have serious advice

Find the root of the following equation: (6+x)2−x2=168
Answer:
No solutions (roots)
Step-by-step explanation:
The root of an equation is basically the solution of the equation. If I'm reading the problem correctly, the equation is (6+x)*2 - x*2 = 168.
We distribute the (6+x)*2 part and get 12+2x - 2x = 168. Uh oh.. the 2x terms cancel each other out and we are left with 12=168. Either I'm reading the equation wrong or the equation has no solutions.

4. Line r is mapped onto line m by a dilation centered at the origin with a
scale factor of 4. The equation of line r is 6x – 3y = 12. What is the
equation for line m?
3x - y = 8
Step-by-step explanation:
Since, if a line having points represented by (x,y) is dilated about origin with a scale factor k,
Then the coordinates of the dilated line is obtained by the rule,
Here, line L is,
3x - y = 4
The x-intercept and y-intercept of line L are (4/3,0) and (0,-4) respectively,
If the line L is mapped onto line M by a dilation centered at the origin with a scale factor of 2,
Then by the above definition,
The points of the line M are,
(2×4/3, 2×0) and (2×0, 2×-4) ⇒ (8/3,0) and (0,-8)
Hence, the equation of line M passes through the points (8/3,0) and (0,-8)

I need help with solving for x. Then find the measure of the base angle. Please
Answer:
x = 8 base angle = 81 degrees
Step-by-step explanation:
Answer:
x = 8
base angle = 81 deg
Step-by-step explanation:
we observe that because the given triangle is a isosceles triangle, the base angles must be the same.
Hence the missing base angle must also be (10x+1)°
recall that all internal angles of an triangle must add up to 180 deg,
hence
180° = sum of all internal angles
180° = 18° + (10x+1)° + (10x+1)°
180° = 18° + 2(10x+1)° (subtracting 18 from both sides)
180 - 18 = 2(10x+1)
162 = 2(10x+1) dividing both sides by 2)
162 / 2 = 10x + 1
81 = 10x + 1 (subtracting 1 from both sides)
81 - 1 = 10x
10x = 80 (divide both sides by 10)
x = 80/10
x = 8 (answer)
substituting x = 8 into the expression for the base angle
base angle = (10x+1)
= 10(8) + 1
= 10 + 1
= 81

trey had 440 songs on his mp3 player.now he has 473 songs.what is the percent of increase in the number of songs on his mp3 player?
round to the nearest tenth if necessary.
Answer:
There is 7.5% increase in the number of songs on his mp3 player.
Step-by-step explanation:
Original Songs in mp3= 440 songs
Final Songs in mp3= 473 songs
We need to find percent of increase in the number of songs on his mp3 player.
The formula used is: [tex]Percent \ of \ increase = \frac{Final \ Value \ -\ Original \ Value}{Original \ Value} \times 100[/tex]
Now putting values and finding percent of increase
[tex]Percent \ of \ increase = \frac{Final \ Value \ -\ Original \ Value}{Original \ Value} \times 100\\Percent \ of \ increase = \frac{473-440}{440} \times 100\\Percent \ of \ increase = 7.5\%[/tex]
So, there is 7.5% increase in the number of songs on his mp3 player.

ok will somebody explain this to me? this has nothing to do with school. just - what?
Answer:
Step-by-step explanation:
so 49.8004 is what it is 0.001 left. 1 x or divide it stay the same
exp: 1[tex]1\sqrt{2}[/tex]
Explanation:
Whenever you divide by a fraction, you multiply by the reciprocal of that fraction, so 49.8004 / 0.001 would be 49.8004 / 1/1000, which would be 49.8004 * 1000/1, which is 49,800.4.
If you think about it, the problem translated into words is "How many 0.001's fit into 49.8004", which is a big number, because a lot of 0.001's can fit inside 49.8004.
3. Solve for a
5(a-2) = 2(10+a)
it’s due by midnight and can you also tell me how you got the answer
Answer:
a=10
Step-by-step explanation:
distribute on both sides to get
5a-10=20+2a
add/subtract like terms
5a-2a=3a
20+10=30
so the equation is
3a=30
divide 30 by 3 and you get 10
Answer:
a = 10
Step-by-step explanation:
[tex]5(a - 2) = 2(10 + a) \\ \\ 5a - 10= 20 + 2a\\ \\ 5a - 2a= 20 + 10\\ \\ 3a = 30\\ \\ a = \frac{30}{3} \\ \\ \huge \red{ \boxed{a = 10}}[/tex]
