Step-by-step explanation:

m ∠WBX = 180° - m ∠3

m ∠ZAY = 180° - m ∠4

ΔWBX ≅ ΔZAY as per SAS postulate

∠W ≅ ∠Z as corresponding angles of congruent triangles

As per above the triangle WTZ is isosceles

y intercept Y=3

I only know the y intercept have a good day

Answer:

on line 13, where it says 1125

Answer:

Line 3

Step-by-step explanation:

L1  1126  10/22    NY Sport (Basketball Shoes)   $87.00  -87.00  $218.50

L2 Debit 10/25  Gary's Country Market            $38.50  -38.50  $180.00

L3 1127   10/25  Iggy's Skate Shop (Skateboard)  $188.00  -188.00  $8.00

L4          10/25  Cash Deposit (Birthday Money)  $20.00 +20.00 $28.00

L5 Debit  10/30  McDonuts                                    $5.95     -5.95     $22.05

The mistake is on line 3.

He subtracted $188 from $180 and got $8.

He should have gotten -$8 instead of $8.

Answer:

1.306

Step-by-step explanation:

1.3 is bigger than

1.03

Answer:

1.306 is greater

Step-by-step explanation:

In the ones place, the number one is equal for both numbers, so you move to the next number in the tenth place, which is .0 and .3 Three is greater than zero, which makes 1.306 greater than 1.036.

Answer:

Step-by-step explanation:

Compound Inequalities is a method to find the variable value for the given compound inequalities. The two inequalities would be joined by the word 'and' or 'or'. It is presented in a number line. When the arrow points away from each other in the number line, then the inequalities are joined by 'and', if arrow points on same direction ...

Answer:

The error was done in Step E, because student did not multiply [tex]2\cdot x -8[/tex] by the negative sign in numerator. Step E must be [tex]\frac{2\cdot x -5}{(x+4)\cdot (x-4)}[/tex].

Second image attached

The error was done in Step C, because the student omitted the [tex]2\cdot a \cdot b[/tex] of the algebraic identity [tex](a+b)^{2} = a^{2}+2\cdot a\cdot b +b^{2}[/tex]. Step C must be [tex]5\cdot x = x^{2}+4\cdot x + 4[/tex]

Step-by-step explanation:

First image attached

The error was done in Step E, because student did not multiply [tex]2\cdot x -8[/tex] by the negative sign in numerator. The real numerator in Step E should be:

[tex]3-(2\cdot x -8)= 3-2\cdot x+8 = 11-2\cdot x[/tex]

Hence, Step E must be [tex]\frac{2\cdot x -5}{(x+4)\cdot (x-4)}[/tex].

Second image attached

The error was done in Step C, because the student omitted the [tex]2\cdot a \cdot b[/tex] of the algebraic identity [tex](a+b)^{2} = a^{2}+2\cdot a\cdot b +b^{2}[/tex]. Step C must be [tex]5\cdot x = x^{2}+4\cdot x + 4[/tex]

And further steps are described below:

Step D

[tex]x^{2}-x+4 = 0[/tex]

Which according to the Quadratic Formula, represents a polynomial with complex roots. That is: ([tex]a = 1[/tex], [tex]b = -1[/tex], [tex]c = 4[/tex])

[tex]D = b^{2}-4\cdot a\cdot c[/tex]

[tex]D = (-1)-4\cdot (1)\cdot (4)[/tex]

[tex]D = -17[/tex] (Conjugated complex roots)

Step E

[tex](x-0.5-i\,1.936)\cdot (x-0.5+i\,1.936) = 0[/tex]

Step F

[tex]x = 0.5+i\,1.936\,\lor\,x = 0.5-i\,1.936[/tex]

Step-by-step explanation:

Answer:

Well, you didn't give a picture of the available mapping diagrams, so I can't tell you that.  However, I CAN tell you that the relation is not a function.

Step-by-step explanation:

A function occurs when each input only has one output.  For example if the input is 5, it can only give 1 y-value out.  It cannot give 2,3,4...etc values.  This relation is not a function because -5 maps to both -4 and 3.  That's one input to two outputs, which breaks the rules of a function.

Step-by-step explanation:

just multiply 1323.80 and 0.82

Number of books in non fiction section  = 200

Number of books in fiction section  = 800

Number of books in reference section  = 850

Step-by-step explanation:

Total number of books in the library = 1850

Let us assume, number of books in non fiction section = m

Number of books in fiction section= 4 x Number of books in non  fiction

= 4  x  (m)

So, the number of books in reference section = 650 + m

Now, Total Number of books =  Number of { Fiction + Non- Fiction + Reference} Books

or,  1850 =  m + (4 m)  + 650 + m

or, 6 m + 650 = 1850

⇒ 6 m = 1850 - 650 = 1200

or, m = 1200 / 6 = 200  

⇒ m = 200

Hence, the number of books in non fiction section  = 200

Number of books in fiction section  =  4 m = 4 x 200 = 800

Number of books in reference section = 650 + m  = 200 + 650 = 850

Answer:

38 cents per ounce

Answer: $0.05

Step-by-step explanation:

Answer:

Add 3.8 to both sides of the equation.

Step-by-step explanation:

12w−3.8=12.4

Add 3.8 to both sides.

12w=12.4+3.8

Add 12.4 and 3.8 to get 16.2.

12w=16.2

Divide both sides by 12.

w= 12/16.2

​Expand  12/16.2 by multiplying both numerator and the denominator by 10.

w= 162/120

​Reduce the fraction  162/120 to lowest terms by extracting and canceling out 6.

w= 27/20 also equal to 1.35

Answer:

20(n + 10)

20n + 200

Step-by-step explanation:

We can write two expressions for the area of the figure by treating the figure as one whole rectangle, and also as two different rectangles in one.

The two expressions are as follows:

Expression of Area as one whole rectangle:

Area of a rectangle = length × width

Length = (n + 10) ft

Width = 20 ft

Area = (n + 10)× 20 = 20(n + 10)

Area of rectangle as two rectangles in one piece:

Area of the larger rectangle = length × width = n × 20 = 20n

Area of the smaller rectangle = length × width = 20 × 10 = 200

Total area = 20n + 200

Answer:

Step-by-step explanation:

z/m - z/n = 1                         Take out z as a common factor.

z (1/m - 1/n) = 1                      Find the common denominator of the 2 fractions

m * n is the common denominator. Multiply the two fractions by mn

z (n - m)/mn = 1                     Multiply by mn

z (n - m) = mn                       Divide by n - m

z = mn/(n - m)

The last line is your answer.
