(x+2)+10=44 please help
Answers
Answer:
[tex]x=32[/tex]
Step-by-step explanation:
Given the equation:
[tex](x+2)+10=44[/tex]
Begin by subtracting 10 from both sides of the equation:
[tex]x+2=34[/tex]
Then, subtract 2 from both sides of the equation to find the value of [tex]x[/tex]:
[tex]x=32[/tex]
-
You can check your answer by substituting the x-value into the initial equation:
[tex](32+2)+10=44[/tex]
[tex]34+10=44[/tex]
[tex]44=44[/tex]
Since both sides of the equation are equal, our solution is correct.
Answer:
[tex] = > (x + 2) + 10 = 44[/tex]
Subtracting 10 from both sides:
[tex] = > (x + 2) + 10 - 10 = 44 - 10[/tex]
[tex] = > x + 2 = 34[/tex]
Subtracting 2 from both sides:
[tex] = > x + 2 - 2 = 34 - 2[/tex]
[tex] = > x = 32[/tex]
Thus,the value of x is 32.
For checking:
[tex] = > (x + 2) + 10 = 44[/tex]
Putting x=32
[tex] = >( 32 + 2) + 1 0= 44[/tex]
[tex] = > 32 + 2 + 10 = 44[/tex]
[tex] = > 34 + 10 = 44[/tex]
[tex] = > 44 = 44[/tex]
Why does the common ratio in an infinite geometric series have to be between 1 and -1? Why doesn't -2 or 2 work? Please help with this. Thanks in advance!
Answers
Answer:
A n+1 / A n the ratio of successive terms will be less than 1 if A is between -1 and 1 so successive terms will have a ratio less than 1 and can be determined
If A n+1 / A n > 1 then successive values of the given ratio will not approach a constant value
If you write the value of the nth term as L = a r^(n - 1) one can see that r^(n - 1) approaches a fixed value if r between -1 and 1 but not if | r | > 1

The front of a house is in the shape of a hexagon with two right angles.
The other four angles are all the same size.
Calculate the size of one of these angles.
Answers
Answer: 135°
Step-by-step explanation:
The sum of the interiors angles of the hexagone is (6-2)*180°=720°
Two angles are right: 2*90°=180°
The sum of the four angles is 720°-180°=540°
Each angle is 540°/4= 135°

A boy's age in ten year time will be four times his age five years ago. Find his present age.
Answers
Answer:
He is ten.
Step-by-step explanation:
10 yrs old. Go ahead 10 yrs to make 20. Which is four times as much as five years old. (Which is 5 years before 10)
Hope this helps! :)
Answer:
Present age = 10
Step-by-step explanation:
Let us assume that,
→ Present age = x
Forming the equation,
→ x + 10 = 4(x - 5)
Now the value of x will be,
→ x + 10 = 4(x - 5)
→ x + 10 = 4x - 20
→ x - 4x = -20 - 10
→ -3x = -30
→ x = -30/-3
→ x = 30/3
→ [ x = 10 ]
Hence, the boy's age is 10.

Is this a true or false question? Because nothing further can be done with the equation above. If so, the equation above is false.
what equation represents the line that passes through the points (7,15) and (-4,4)?
Answers
Equation of line is y = mx +b
Passing through (-3,7 )
X= -3, y= 7
plug in these
7 = -3m + b ... .Eq1
Also X = 4 , y= 10
10 = 4m + b ............... Eq 2
Solve Eq 1 and Eq 2 for m and b
m= 3/7
b= 58/7
Thus y =( 3/7) X + 58/7 is equation of line

For which value of x is the figure a rectangle?
Answers
Answer:
x = 11
Step-by-step explanation:
The vertices of a rectangle are right angles (90° ) , then
5x + 2 + 3x = 90
8x + 2 = 90 ( subtract 2 from both sides )
8x = 88 ( divide both sides by 8 )
x = 11

Let f(x) = 12 over the quantity of 4 x + 2. Find f(−1). (1 point)
Answers
Answer:
-6
Step-by-step explanation:
Hope I understand your "f(x) = 12 over the quantity of 4 x + 2" correctly
f(x) = 12 / 4x +2
Now so they want a f(-1), as u can see they substituted the x for - 1, therefor do that the same to the right side
f(-1) = 12/ 4(-1) + 2
f(-1) = 12 / - 4+2
= 12/ - 2
= - 6

Answers
Answer:
65° and 115°
Step-by-step explanation:
Supplementary angles add up to 180
So if you add A and B you get 180°
x + 50 + x + 100 = 180
2x + 150 = 180
2x = 30
x = 15
A = 15 + 50
A = 65
B = 15 + 100
B = 115
