3. When six is added to six times a number the result obtained is the same as when the number is added to 10 and
the result multiplied by 3. Form an equation and solve it to find the unknown number.
Answer:
Equation x(6+6)=3(10+x)
x=3.33
Step-by-step explanation:
Form an equation:
x(6+6) The result of 6+6 is multiplied by x, so you would put 6+6 in a bracket (you do what's inside the bracket first in BODMAS) and the x on the outside so you times the result by x.
3(10+x) The number x is added to 10 and the result is multiplied by 3, so the 10+x would go in a bracket with 3 on the outside.
These equal each other, so you would put an equals sign between it to make:
x(6+6)=3(10+x)
Solve to find x:
12x=30+3x You expand the brackets to make this.
9x=30 You would move 3x to the other side by doing the inverse and taking away 3x from 12x.
x=3.33 To get x you would have to do 30 divided by 9 which is 3.33.
Hope this helps :)
The number asked is 8
What is an equation?The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, When six is added to six times a number, the result obtained is the same as when the number is added to 10 and the result multiplied by 3.
Let the number be x,
Establishing, the equation,
6x+6 = 3(x+10)
6(x+1) = 3(x+10)
6/3(x+1) = x+10
2(x+1) = x+10
2x+2 = x+10
x = 8
Hence, the required number is 8.

m∠ABC = (9x + 4)° and m∠DEF = (13x − 22)°. If ∠ABC and ∠DEF are supplementary, what is the measure of each angle?
Answer:
∠ABC measures 85° and ∠DEF measures 95°.
Step-by-step explanation:
We are given that ∠ABC and ∠DEF are supplementary. Then by definition:
[tex]\displaystyle m\angle ABC + m\angle DE F = 180^\circ[/tex]
Substitute:
[tex]\displaystyle \left(9x+4\right) + \left(13x-22\right) = 180[/tex]
Solve for x. Combine like terms:
[tex]22x -18 = 180[/tex]
Add:
[tex]\displaystyle 22x = 198[/tex]
And divide. Hence:
[tex]\displaystyle x = 9[/tex]
To find the measure of ∠ABC, substitute and evaluate:
[tex]\displaystyle \begin{aligned}m\angle ABC &= 9x + 4 \\ &= 9(9) + 4 \\ &= 81 + 4 \\ &= 85^\circ \end{aligned}[/tex]
And:
[tex]\displaystyle \begin{aligned}m\ngle DE F &= 13x - 22 \\ &= 13(9) - 22 \\ &= 117-22 \\&= 95^\circ \end{aligned}[/tex]
In conclusion, ∠ABC measures 85° and ∠DEF measures 95°.

WILL.MARK BRAINLEST. ( The length of a rectangular garden is 5m longer than its breadth .If its perimeter is 150 m,find the area of the garden ) step by step
Answer:
1400m^2
Step-by-step explanation:
Solution,
Let the breadth of the rectangle be x m, then the length of the rectangle will be x+5 m,
Now,
Perimeter of the rectangle=2(l+b)
150=2(x+5+x)
150=2(2x+5)
150=4x+10
150-10=4x
140=4x
140/4=x
35=x
So, the breadth of the rectangle=35 m
and length=(35+5)m=40m
Again,
Area of the rectangle=l×b
=40m×35m
=1400 m^2
I hope it helped U
stay safe stay happy
Answer: Area= 1400[tex]meter^{2}[/tex]
Step-by-step explanation:
ok so we can assume the
breadth=X
so, length = X+5 (because the length is 5 meters more than the breadth)
perimeter= 150 meters
the formula of the perimeter of a rectangle = 2 x ( Length + Breadth)
so now if we put the values,
2 * ( X+5 +X) = 150 ( because 150 is the perimeter)
2 * (2X + 5) = 150 (the value became 2x because when we add two variables with the same value it will be written as 2(any variable)).
now we multiply 2 with both sides
so ( 2 * 2X) + (2 * 5)
hence, 4X + 10 = 150
now we will solve the equation,
4X= 150 -10 (because we did transposal the signs will change from "+" to "-")
4x= 140
again with the transposal (when we write a number with a variable it shows that it means the number multiplied by the variable in this case it is 4 multiplied by X ) so when we transpose we will have to divide because multiplication turns into division while transposing
so now,
X= 140÷4
which is equal to 35
so finally X = 35
so as we have written in the beginning breadth= X
and LENGTH= X+5
so now we have found X
BREADTH= 35
LENGTH= 40 (because 35+5 is 40)
now we have to find area the formula for finding the area is LENGTH×BREADTH
so, 40 × 35 = 1400
now we put the unit which is square meters also known as [tex]m^{2}[/tex]
so there is your final answer 1400[tex]m^{2}[/tex]

A simple pulley with the give radius 4 in used to lift heavy objects is positioned 10 feet above ground level. Given that the pully rotates 720 degrees determine the height yo which the object is lifted.
9514 1404 393
Answer:
50.3 inches
Step-by-step explanation:
720 degrees is 2 full turns, or twice the circumference of the pulley. The circumference is given by ...
C = 2πr
C = 2π(4 in) = 8π in
Then 2 times that is ...
height lifted = 2(8π in) = 16π in ≈ 50.3 in
The object was lifted about 50.3 inches.

CORRECT ANSWER ONLY PLEASE!!! The table of values represents the function g(x) and the graph shows the function f(x).
Answer: Choice C. f(x) and g(x) have a common x intercept.
Explanation:
The graph of f(x) shows it has an x intercept at x = 2, since this is one location where the curve crosses the x axis.
The g(x) table shows that x = 2 and y = 0 pair up together. This is the location (2,0). This location is the exact same x intercept as described earlier.
This is the common x intercept the two functions share. This means the two functions cross or intersect at this location.
Is 8.24 a rational number?
Answer:
8.24 is not a rational number
Step-by-step explanation:
The simple way to remember or find if the number is rational or not is that
* Rational numbers are always in the form of p/q and q should not be equal to zero
here u can even see 8.24 can be written as 8.24/0 so it is clearly showing that it is not a rational number

H(x) = 1/x+2 and k(x) = 3x - 4
h[k(x)] =
A.(3x - 4)/(x+2)
B. 1/(4x - 2)
C. 1/(3x - 2)
Answer:
= 1/ (3x-2)
Step-by-step explanation:
H(x) = 1/(x+2)
k(x) = 3x - 4
h[k(x)] = place the function k(x) in for x in the function h(x)
= 1/(3x-4 +2)
Combine like terms
= 1/ (3x-2)
Hey there! I'm happy to help!
What we need to do is take the value of k(x) which is 3x-4 and plug it into the function h(x).
This is because our x in the function h[k(x)] is k(x), so we will substitute that value for x in that formula and that will give us our answer.
H[(k(x)]=1/(3x-4+2)
And combine like terms
H[(k(x)]=1/(3x-2)
So, our answer is C. 1/(3x-2)

What is the relationship between the number of sides in a regular polygon and
number of lines of symmetry?
Answer:
Divide 360 by the difference of the angle and 180 degrees. For example, 360 divided by 15 equals 24, which is the number of sides of the polygon. Divide 360 by the amount of the exterior angle to also find the number of sides of the polygon.

The table shows the estimated number of deer living in a forest over a five year period.
Year Number of deers
0 89
1 55
2 34
3 21
4 13
Now we have to find the model representing this situation. Difference in number of deer, in the forest.
We can see there is a common ratio between each successive term r = = 0.618
r = = 0.618
so it can be represented by an exponential model.

1= 39 degrees
2: 40 degrees
3: 41 degrees
4: 42 degrees
Answer:
A
Step-by-step explanation:
This uses the sine law.
Sin(theta)/113 = sin(42)/120 Multiply both sides by 113
sin(theta) = 113*sin(42)/120
sin42 = 0.6691
sin(theta) = 113 * 0.6691 / 120
sin(theta) = 0.630008
theta = sin-1(0.63008)
theta = 39.1 Looks Like A

Find the mean, median, and mode of 14, 15, 3, 15, 14, 14, 18, 15, 8, 16.
Answer:
mean: 13.2 (average)
median: 14.5 (Center)
mode: 14 and 15 (because data is bimodal so there are two modes
Step-by-step explanation:
Answer:
mean = 13.2, median = 15.5, mode = 18
Step-by-step explanation:
mean = 14+15+3+15+14+14+18+15+8+16/10
= 132/10 = 13.2
median =[ (n/2)th term + (n/2+1)term ]/2
here n is even so this formula is applied and before this is done, the numbers given are to be arranged in ascending or descending order
= [10/2 + (10/2+1)]/2
= [5th term + 6th term]/2
= (15+16)/2
= 31/2 = 15.5
mode = 18
