Answer:
In ΔECD
<E = <C = <D
using angle sum property of triangle
<E + <C + <D = 180°
<E + <E + <E = 180° ( As <E = <C = <D )
3<E = 180
<E = 60°
NOW
<BCA + <ACE + <ECD = 180 (L. P. A.)
50° + <ACE + 60° =180
110 + <ACE = 180
<ACE = 70°
NOW as
AC = AE
So using property of triangle that angle opposite to equal sides are equal we get
<ACE = <AEC = 70°
In triangle ΔAEC
Now using Angle sum property of triangle
<ACE + <AEC + <CAE = 180°
70° + 70° + x = 180
140 + x = 180
x = 40°
Now in ΔABC
AB = AC
using property of triangle that angle opposite to equal sides are equal
So <ACB = <ABC = 50°
Now using angle sum property of triangle in ΔABC
<ACB + <ABC + <CAB = 180
50 + 50 + y = 180
100 + y = 180
y = 80°
so x = 40° and y = 80°
Model the unknown number problem by writing an algebraic expression. Then complete the statements. The class was divided into three equal groups. The number of students in class is represented by .

c a c....................................................................................................................
The correct algebraic expression for this scenario is x/3.
The unknown number of students in the class can be represented by the algebraic expression "x."
The statement "The class was divided into three equal groups" implies that the number of students, represented by "x," is divided by 3.
Therefore, the correct algebraic expression for this scenario is:
x/3.
Here, "x" represents the total number of students in the class, and "x/3" represents the number of students in each of the three equal groups when the class is divided equally.

Every time Mary bakes a batch of brownies, she uses 1/5 cup of chocolate. If she has 8/10 cup(s) of chocolate remaining, how many batches of brownies can Mary make? Input your answer as a whole number.
giving 35 points if u answer.
Answer:
4 batches
Step-by-step explanation:
just divide 8/10 by 1/5 to get 4 :)
Step-by-step explanation:
Number of cups of chocolate is directly proportional to the number of batches of brownies.
1/5 cups of chocolate = 1 batch of brownies
=> 8/10 cups of chocolate = (8/10) / (1/5)
= 4 batches of brownies.
Hence Mary can make 4 more batches.

Find the general solution to the equation y(5) - 4y(4) + 4y(3) = 1.
Answer:
y= -1/23
Step-by-step explanation:
The equation y(5)-4y(4)+4y(3)=1 can be solved thus:
Work on brackets first:
5y-16y+12y=1
Add up y values
5y-28y=1
Divide both sides of equation
-23y=1
y=1/-23
Therefore the value of y is -1/23

Show that x+y:x-y=3:2
We have,
x+y:x-y=3:2
To prove that, x+ y : x - y = 3:2.
x+y=3
And,
x+y = 2
Adding (1) and (2), we get
x+y+x-y=3+2
⇒2x=5
⇒ x =
Put x = in (1), we get
+y=3
⇒ y=3-=
x+y:x-y=
=3:2
So, x+y:x-y=3:2.
Find the midpoint of the line segment whose endpoints are (0, 1/2 ) and (0, 3/4).
A: 0,2/3
B: 0,5/8
C: 0, 1 1/4
Answer:
B: 0, 5/8
Step-by-step explanation:
First, add the abcissas (x coordinates).
0 + 0 = 0
Then, divide the result by 2.
0 divided by 2 = 0
Then, add the ordinates (y coordinates).
1/2 + 3/4 = 1 1/4
Then, divide the result by 2.
1 1/4 divided by 2 = 5/8
The midpoint is 0, 5/8

write an expression that is equivalent to 1/3x+3/4+2/3x-1/4-1/3-2/3x
Answer: 1/3x + 1/6
Step-by-step explanation:
The expression that is equivalent to 1/3x+3/4+2/3x-1/4-1/3-2/3x would be:
= 1/3x + 2/3x - 2/3x + 3/4 - 1/4 - 1/3
= 1/3x + 3/4 - 1/4 - 1/3
= 1/3x + 1/2 - 1/3
= 1/3x + 3/6 - 2/6
= 1/3x + 1/6
Answer:
1/3x + 2/4
Step-by-step explanation:
(1/3x + 2/3x = 3/3x/ 1 - 2/3 = 1/3) (3/4 - 1/4 = 2/4
What is the slope of the line shown in the graph?
A 3/2
B) 2/3
C) -3/4
D) -2/3
Answer:
D.
Step-by-step explanation:
y-intercept is (0, 3)
x-intercept is (4.5, 0)
formula to find the slope from two points is
[tex]slope = m = \frac{y2 - y1}{x2 - x1} = \frac{y1 - y2}{x1 - x2} \\ [/tex]
then the slope of the line that crosses (0, 3) & (4.5, 0) is
[tex]m = \frac{3 - 0}{0 - 4.5} = \frac{3}{ - 4.5} = - \frac{3}{ \frac{9}{2} } = - \frac{2}{3} [/tex]

write a polynomial function in it's factored form with zeros 5, -1, and 2
Answer:
(x - 5)(x + 1)(x - 2) = 0
Step-by-step explanation:
If a polynomial function has roots a, b, and c, then it is (x - a)(x - b)(x - c).
The roots here are 5, 1, and 2, so the factors are
(x - 5)(x - (1))(x - 2)
The function is:
(x - 5)(x + 1)(x - 2) = 0
6) Tell whether -3 is a solution of the inequality.: y +6<4
A-solution
B-not a solution
Answer:
A - Yes, it's a solution
Answer:
Yes, it is a solution.
Step-by-step explanation:
The reason why it is a solution because when you plug -3 into the y and add -3+6<4, you will get -9<4. -9 is less than 4 because the 9 is a negative. Hope this helps!
