dlinn [17]

Answer:

0.2 or 1/5

Step-by-step explanation:

-4(50x - 20) = 10x + 15 + 23

-200x + 80 = 10x + 38

80 = 210x + 38

42 = 210x

0.2 = x

as the schools sign language interpreter kiran gets paid 35.50 for every parent-teacher conference that he attends. He also gets

yKpoI14uk [10]

<u>The interpreter attended </u><u>22 parent-teacher conference</u><u> and </u><u>5 school related assembly</u>

To solve this problem, we would write out two set of linear equations.

The data given on this problem are

parent-teacher conference = $35.50
school related assembly = $42
The total number of engagements = 27

Let x represent the number of parent-teacher conference

let y represent the number of school related conference

<h3>Equations</h3><h3> $x+y = 27...equation (i)\\35.50(x)+42y=991...equation(ii)$ </h3>

From equation (i)

$x+y = 27\\x = 27-y...equation(iii)\\$

Put equation(iii) into equation (ii)

$35.50x+42y=991\\35.50(27-y)+42y=991\\958.50-35.50y+42y=991\\6.50y=991-958.50\\y=5$

Put y = 5 into equation 1

$x+y=27\\y = 5\\x+5=27\\x=27-5\\x=22$

From the above calculations, he attended 22 parent-teacher conference and 5 school related assembly.

Can someone please help me on this??

Usimov [2.4K]

Answer:

Step-by-step explanation:

To solve this use the equation $x^2 -15x - 50 = y$ given in the problem and the value y = 50. Substitute y = 50 then solve for x by factoring.

$x^2 -15x - 50 = 50\\x^2 - 15x -100 = 0$

Find two numbers which multiply to -100 and also add to -15. The numbers are -20 and 5.

So the factored form is (x-20)(x+5) = 0.

Set each factor equal to 0 and solve.

(x-20) = 0 so x = 20.

(x+5)=0 so x = -5.

This means the temperature is 20 degrees C or -5 degrees C. Only 20 is an option. The solutions is C.
