Answer:

Step-by-step explanation:

4x+4+2x+2+7x-8=180

add like terms

4x+2x+7x=13x

4+2-8=-2

13x-2=180

+2 +2

13x=182

/13 /13

x=14

now you plug in X

4(14)+4= 60

2(14)+2= 30

7(14)-8= 90

add ur stuff up see if u get 180

60+30+90=180

#1:

A)

you need to know where a vertex goes on a isosceles triangle...

I attached a picture that explains it.....

you also want to label triangle.... XYZ

I put a picture on of how you should of labeled the triangle...

B)

so we need to find Measure for each angle.... REMEMBER: A triangle angles needs to = 180.

so your equations will need to be equal to 180.

4x+4+2x+2+7x-8=180

so we combine liked terms

4x+2x+7x=13x

4+2-8=-2

13x-2=180

+2 +2

13x=182

/13 /13

x=14

now you plug in X

4(14)+4= 60

2(14)+2= 30

7(14)-8= 90

now you want to check you answers so add them up to see if your answers equal 180...

60+30+90=180

to be continued.... i do second question on a second answer since i dont want pictures to get mixed up

A test is worth 50 points. Multiple- choice questions are worth 1 point, and short answer questions are worth 3 points. if the t
bagirrra123 [75]
Correct answer is C. 
m + 3s = 50 
the total number of questions is 20. since the paper is made of only multiple choice and short answer questions, the sum of the multiple choice and short answer questions should be 20.
since multiple choice is 'm' and short answer is 's'
then m + s = 20
but theres no option for that 
if we take the number of points 
points for 1 multiple choice question - 1
then points for m number of multiple choice questions = 1 * m = m
points for 1 short answer - 3
then points for s number of short answer question = 3 * s = 3s
then total number of points = m + 3s
and the total number of points = 50
therefore 
m + 3s = 50
this is the correct answer C.
