PLEASE HELP ME !!!!!!
Answer:
According to the parallel lines theorem, the angle ∠JOP = ∠OPK
Thus, a = 45°.
Now according to the opposite angles theorem, ∠OPK = ∠NPL
thus, x = 45°.

Answer: 7 5/7 (the bottom one)
Step-by-step explanation:
30 divided by 2 = 15 (do the same to 42 and get 21)
This then creates the fraction: 15/21
Now, divide this fraction by 3 and get 5/7
Add back in the seven because you aren't dividing the whole number.
Your final answer is now 7 and 5/7 (together: 7 5/7)
Triangle EFG has vertices E(-3, 1), F(1, 1), and G(4, 5). Find the coordinates of the image of point F
after a reflection across the x-axis.
O (1,1)
None of the other answers are correct
O (1,-1)
o (-1, -1)
O (-1,1)
Answer:
(1,-1)
Step-by-step explanation:
if its asking for a reflection on the x-axis, change the y's to the opposite of what it is.
Example, (5,6) change it to (5,-6)
its the same thing for the reflection on the y-axis
(7,-8) change it to (-7,-8)

Jason says that 10 less than one third of his age is 11 years old. How old is Jason?
Answer:
63
Step-by-step explanation:
Jason age will be 63 years.
What is an expression?
Expression in math is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
The condition is given as;
'' Jason says that 10 less than one third of his age is 11 years old. ''
Now,
Let age of Jason = x years
Then, By the given condition we formulate;
1/3 x - 10 = 11
Solve for x as;
1/3 x - 10 = 11
Add 10 both side;
1/3 x - 10 + 10 = 11 + 10
1/3 x = 21
Multiply by 3;
x = 63
Thus, Jason age will be 63 years.

For weeding the garden Eugene was given
$8. Now he has $38. How much money did
he have before?
Answer:
$30
Step-by-step explanation:
$38-$8=$30
Answer: 30
Since Eugene just got $8, and the question is asking how much he had before that, we have to subtract 8 from 38.
38 - 8 = 30
So, the answer is 30. Hope this helps!
The school that Danielle goes to is selling tickets to a spring musical. On the first day of ticket sales the school sold 10 adult tickets and 13 student tickets for a total of $234. The school took in $97 on the second day by selling 5 adult tickets and 4 student tickets. What is the price each of one adult ticket and one student ticket?
Answer:
Price of Adult tickets =$ 13
Price of student tickets =$ 8
Step-by-step explanation:
Lets us represent the price of adult tickets = x
The price of student tickets = y
On the first day of ticket sales the school sold 10 adult tickets and 13 student tickets for a total of $234.
= 10 × x + 13 × y = $234
= 10x + 13 y = 234
The school took in $97 on the second day by selling 5 adult tickets and 4 student tickets.
5 × x + 4 × y = $97
= 5x + 4y = 97
Hence:
10x + 13y = 234......Equation 1
5x + 4y = 97......... Equation 2
We solve by elimination method
Multiply the equation 1 by 5 and equation 2 by 10 which are the coefficient of x
10x + 13y = 234......Equation 1 × 5
5x + 4y = 97......... Equation 2 × 10
50x + 65y = 1170......Equation 3
50x + 40y = 970..... Equation 4
Subtract Equation 4 from Equation 3
25y = 200
y = 200/25
y = 8
Therefore the price of student ticket = $8
Note that
5x + 4y = 97......... Equation 2
5x + 4 × 8 = 97
5x = 97 + 32
5x = 65
x = 65/5
x = 13
Therefore price of adult tickets = $13

Arabica coffee costs $28 per pound and Robusta coffee
costs $8.75 per pound. How many pounds of Arabica coffee
must you mix with 3 pounds of Robusta coffee to make a
blend that costs $15.50 per pound?
Answer:
1.62 pounds
Step-by-step explanation:
Let x be the pounds of Arabica
Take the number of pounds times the cost of each of the coffees individually
This must be equal to the number of pounds times the cost together
x * 28 + 8.75 *3 = ( x+3) 15.50
28x+26.25=(x+3)15.50
Distribute
28x+ 26.25 = 15.50x + 46.50
Subtract 15.50x from each side
28x-15.50x +26.25 = 15.50x +46.50-15.50x
12.50x + 26.25 = 46.50
Subtract 26.25 from each side
12.50x +26.25-26.25 = 46.50-26.25
12.50x = 20.25
Divide each side by 12.5
12.5x/12.5 = 20.25/12.5
x =1.62
Answer:

Linear equation
A line with the slope of 1/2 pass through the point (3,-2)
a) Write the equation of the line in Point - Slope Form.
b) Write the equation of the line in Slope - intercept form.
Answer:
see explanation
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = [tex]\frac{1}{2}[/tex] and (a, b) = (3, - 2) , thus
y - (- 2) = [tex]\frac{1}{2}[/tex] (x - 3) , that is
y + 2 = [tex]\frac{1}{2}[/tex]( x - 3) ← in point- slope form
(b)
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = [tex]\frac{1}{2}[/tex] , thus
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute (3, - 2) into the partial equation
- 2 = [tex]\frac{3}{2}[/tex] + c ⇒ c = - 2 - [tex]\frac{3}{2}[/tex] = - [tex]\frac{7}{2}[/tex]
y = [tex]\frac{1}{2}[/tex] x - [tex]\frac{7}{2}[/tex] ← in slope- intercept form
If m\angle CED=101 then what is m\angle CEH∠CEH
Answer:
m∠CEH = 79°
Step-by-step explanation:
From the picture attached,
∠CED and ∠CEH are the pair of linear angles.
Since, pair of linear angles are supplementary angles.
m∠CED + m∠CEH = 180°
101° + m∠CEH = 180°
m∠CEH = 180° - 101°
= 79°
Therefore, measure of angle CEH is 79°.
