Amanda and Ndiba are selling flower bulbs for a school fundraiser. Customers can buy packages of tulip bulbs and bags of daffodil bulbs. Amanda sold 6 packages of tulip bulbs and 12 bags of daffodil bulbs for a total of $198. Ndiba sold 7 packages of tulip bulbs and 6 bags of daffodil bulbs for a total of $127. Find the cost each of one package of tulips bulbs and one bag of daffodil bulbs.
Answer:
daffodil = $13 Tulip = $7
Step-by-step explanation:
6t + 12d = 198
7t + 6d = 127
6t = 198 - 12d
t = 33 -2d
substitute
7(33-2d) + 6d = 127
231 -14d +6d = 127
- 8d = -104
d =13
6t + 12(13) = 198
6t +156 = 198
6t = 42
t = 7
10. What value of x and y will make the polygon a
parallelogram?
Answer:
Step-by-step explanation:
20 = 5y
4=y
x+3y = 2(x+y-1)
x+3y = 2x +2y -2
x+3(4) = 2x + 2(4) -2
x +12 = 2x +8 -2
12-8+2 = 2x -x
6 =x
The values of x and y that makes the polygon a parallelogram is 6 and 4 respectively.
What is a parallelogram?A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal, and opposite angles equal.
Given is a polygon,
We know opposite sides of a parallelogram are equal,
Therefore,
5y = 20
y = 20/5
y = 4
And,
Putting y = 4, in x+3y = 2(x+y-1)
x+12 = 2(x+3)
x+12 = 2x+6
x = 12-6
x = 6
Hence, The values of x and y that makes the polygon a parallelogram is 6 and 4 respectively.

Which expression represents the average of three test scores?
Answer:
C) is the correct answer
Step-by-step explanation:
In order to find an average, you need to add x, y, and z and then divide them by 3 because there are 3 test scores, and x, y, and z represent the grades for each test. This is why C) x+y+z/3 is correct.

Answer:
You can use x as the variable. x≤1
Step-by-step explanation:
If m∠P = (19x - 5)° and x = 4, find m∠P and classify the angle (acute, right, obtuse, straight).
Answer:
71 degrees, Acute angle
Step-by-step explanation:
From the question, the equation for the Angle is given to be 19x-5, given in degrees and they want to find the value of the angle when the variable X is equal to 4.
All we need to do is change X with 4 in this equation to get
(19x4)-5) Now we just need to do some basic arithmetic to find out the value.
(76-5)=71, So 71 degrees. Now let's classify all the types of angles
1-89 degrees is a acute angle
90 degrees Is a right angle
91-179 is a obtuse angle
180 is a Straight angle
181-359 is a reflex angle
360 is a full turn.
Notice how our 71 degree angle falls into the category of a acute angle (1-89)
So our final Answer is that the angle is 71 degrees and a acute angle.
Answer:
∠ P = 71° and is acute
Step-by-step explanation:
Acute angle is between 0° and 90°
Right angle = 90°
Obtuse angle is between 90° and 180°
Straight angle = 180°
Given
∠ P = 19x - 5 ← substitute x = 4
= 19(4) - 5 = 76 - 5 = 71° ← acute angle

a. i pi -8.6157
b. i pi + 7.6157
c. i pi + 6.6157
d. i pi + 5.6157
Answer:
C. [tex]\ln z = 5.6157 + i\,\pi[/tex]
Step-by-step explanation:
Let [tex]z = a + i\,b[/tex], [tex]\forall\, a, b\in \mathbb{R}[/tex], the natural logarithm of a this number is:
[tex]\ln z = \ln \|z\|+i\, \theta[/tex] (1)
Where:
[tex]\|z\|[/tex] - Norm of the complex number, no units.
[tex]\theta[/tex] - Direction of the complex number, in radians.
The norm and direction of the complex number are both defined by:
[tex]\|z\| = \sqrt{a^{2}+b^{2}}[/tex] (2)
[tex]\theta = \tan^{-1}\left(\frac{b}{a} \right)[/tex] (3)
If we know that [tex]z = -274.7 +\,i \, 0[/tex], then the natural logarithm of this number is:
[tex]\|z\| = 274.7[/tex], [tex]\theta = \pi\,rad[/tex]
[tex]\ln z = \ln \|z\|+i\, \theta[/tex]
[tex]\ln z = 5.6157 + i\,\pi[/tex]
Hence, correct answer is C.
