Answer:
y= 95.
180°-120°=60° (adding 120° with x should give you 180°)
x=60°
25°+60°=85°
180°-85°=95
Answer:
y=95
Step-by-step explanation:
we know that the triangle angles sum is 180°
to find Y you should find x
we are going to find x, we know that a straight angle is 180, to find the x you should:
[tex]120+x=180[/tex]
move 120 to the other side with a negative sign:
[tex]x=180-120\\x=60[/tex]
angle [tex]x=60[/tex]
now we know enough angles to find y:
[tex]25+60+y=180[/tex]
25 is given in the picure and 60 is the x angle while 180 is the sum of a triangle angles, we have to flip the equaton to find y:
[tex]25+60+y=180\\85+y=180\\y=180-85\\y=95[/tex]

Which is a factor of x2 – 9x 14? x – 9 x – 2 x 5 x 7.
Answers
Answer:
Step-by-step explanation:
The 2 factors of x^2 - 9x + 14 are (x - 7) and (x - 2) because -7 + -2 = -9 and -7 x -2 = 14.
The factors of the quadratic expression x² – 9x + 14 is (x - 7)(x - 2) option (B) (x - 2) is correct.
What is a quadratic function?Any function of the form [tex]\rm f(x) =ax^2+bx+c[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic function.
It is given that:
The quadratic expression is:
= x² – 9x + 14
Using factor method:
= x² – 7x - 2x + 14
= x(x - 7) - 2(x - 7)
= (x - 7)(x - 2)
The factors of the quadratic expression x² – 9x + 14 is (x - 7)(x - 2)
Thus, the factors of the quadratic expression x² – 9x + 14 is (x - 7)(x - 2) option (B) (x - 2) is correct.

In each of the following, solve for X.
Answers
Answer:
x = 6
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are in proportion, that is
[tex]\frac{MO}{PR}[/tex] = [tex]\frac{MN}{PQ}[/tex] ( substitute values )
[tex]\frac{4+x}{5}[/tex] = [tex]\frac{x-2}{2}[/tex] ( cross- multiply )
5(x - 2) = 2(4 + x) ← distribute parenthesis on both sides
5x - 10 = 8 + 2x ( subtract 2x from both sides )
3x - 10 = 8 ( add 10 to both sides )
3x = 18 ( divide both sides by 3 )
x = 6

Leonardo makes the following purchases at the
Store: 1 backpack for $16.89, 5 spiral notebooks for $1.19, each 1 pack of mechanical pencils for $3.68, 2 packs of lead refills for $1. 88 each
The total amount of these items is,

The transport charge starts with a minimum charge of R8 and thereafter it was increased by R2 for each kilometre. On a particular day the bus was full with passengers from Butterworth. In each and every kilometre there was a passenger getting off while no new passenger entered in the bus. Mr Dlamini was calculating total money in his hand after each passenger was getting out.

long is the shorter piece of wire?
Answers
Answer:
30 cm
Step-by-step explanation:
30+60=90
30×2=60 so 30cm is the answer.
Step-by-step explanation:
If one price is 2 times the other one, that means it's equal to 2 of those parts. Let's decide our total wire by three to account for the larger part.
[tex]90 \div 3 = 30[/tex]
Now we know the shorter piece is 30 cm. To find the longer piece, multiply the shorter piece by 2.
[tex]30 \times 2 = 60[/tex]

Check whether the given value of x is a solution to the equation. Justify your answer. 1/3(x+4)=20. x=56.
Answers
Answer:
True, it is a solution
Step-by-step explanation:
First, let’s distribute 1/3 to x and 4
When we do this, we get:
1/3x+4/3=20
Now, we can solve the equation!
Subtract 4/3 from each side of the equation to isolate the x
We now have 1/3x=18 2/3
Now we divide 1/3 on each side to isolate the x (this is the same as multiplying by 3/1 on each side)
This gets us to x=56
So it is true

From the figure, we can assume the beam forms as AD, BC, EF , GH and so on.
Therefore,

Answer 1 :-
For answering the above questions we use knowledge and practices regarding the questions we can do the activity by making figures of unknown sides by assuming it in the form of x, y.so that we can find the known values.

Here x determines the number of year. For the first year,we will see ( 2 * 1 ) = $2 increase. In the second year, ( 2 * 2 ) =$4 increase and like this goes on, whereas the $25 being constant. "y" determines the total cost for each year.
