For a triangle to be a triangle all the angles have to add up to 180 degrees. So 52 degrees plus 28 degrees would equal 80. So now to find the answer 180 - 80 then your final answer is 100! Hope This Helps

A high school has a total of 850 students. there are 60 more female students than there are make students?

Mrac [35]

Hey. Let me help you on this one.

Let's break this problem down so it's easier for us to comprehend it.

There are 850 students in the school, and the amount of female students equals to the amount of male students + sixty additional females.

Amount of students in school = 850 students

Male students = $X$

Female students = $X+60$

Let's form an equation so we can work with what we have.

$X+(X+60)=850$

Subtract 60 from both sides.

$X+X=790$

Simplify

$2X=790$

Divide both sides by 2.

$X=395$

Answer: There are 395 male students, and 455 female students.

Please help and explain with these 2 math questions!!!!!!

Volgvan

1) -10x+y=4

Now, you should substitute x in every situation.

* x=-2 => -10*(-2)+y=4... 20+y=4... y=-16

* x=-1 =>-10*(-1)+y=4... 10+y=4... y=-6

*x=0 => -10*0+y=4... y=4

* x=1 => -10*1+y=4... -10+y=4... y=14

* x=2 => -10*2+y=4... -20+y=4... y=24

2) -5x-1=y

For example: x=0

-5*0-1=-1

FIND THE EQUATION OF THE LINE . USE EXACT NUMBERS

Alik [6]

Answer:

y = -3x + 7

Step-by-step explanation:

Use points on the graph:

(0, 7) and (2, 1)

Find the slope:

m = (1 - 7)/ 2 = -3

The y-intercept is known b = 7, so the equation is:

y = mx + b
y = -3x + 7
