Here is your answer

$z= 20 degrees$

REASON:

$Concept used$ : The sum of adjacent angles of a parallelogram is 180 degrees.

So, in above given figure

$2z+16+124=180$ (measures of adjacent angles)

$2z+140=180$

$2z=180-140$

$2z=40$

$z= 40/2$

$z= 20$

HOPE IT IS USEFUL

What are the solutions to this quadratic equation x2+6x-5=0

marishachu [46]

Answer:

See Below.

Explanation:

Quadratic Form:

$a {x}^{2} + bx + c$

Quadratic Formula:

$x = \frac{ - b + - \sqrt{ {b}^{2} - 4ac} }{2a}$

Based on the information given from the question, we can deduce:

a = 1

b = 6

c = -5

Now we can substitute all these values into the formula to find x.

$x = \frac{ - 6 + - \sqrt{ {6}^{2} - 4(1)( - 5)} }{2(1)} \\ = - 3 + \sqrt{14} \: or \: - 3 - \sqrt{14}$

Last time, one out of every 4 students in our class was absent. This time, after Jen came back, only one out of every 5 students

VMariaS [17]

Answer: There are 20 students and 4 students are not here today.

Step-by-step explanation:

If the number of students = 4

Let the number of students be 'x'.

Fraction of students absent = $\dfrac{x}{4}$

If the number of students = 5

Fraction of students absent = $\dfrac{x}{5}$

And Jen came back,

So, the fraction of student absent is also written as

$\dfrac{x}{4}-1$

According to question, it becomes,

$\dfrac{x}{5}=\dfrac{x}{4}-1\\\\\dfrac{x}{5}=\dfrac{x-4}{4}\\\\4x=5(x-4)\\\\4x=5x-20\\\\4x-5x=-20\\\\-x=-20\\\\x=20$

Hence, there are 20 students in our school.

And number of students are not here today is $\dfrac{20}{5}=4$
