Answer:
x=16
Step-by-step explanation:
From the Free Response Row,
For the Total Time(in minutes) column
Since x=55-3m and x=8(15-m)
Therefore:
55-3m =8(15-m)
55-3m=120-8m
Collect like terms
-3m+8m=120-55
5m=65
Divide both sides by 5
m=13
Therefore:
x=55-3m=55-3(13)=55-39
x=16
Answer:
I believe it's 15 (3x+5)
Step-by-step explanation:
15 times 3 is 45 and 15 times 5 is 75
3x + 6x = 9x
9x + 2x = 11x
11x is your answer
hope this helps
Answer:
So since the 2 angles are congruent they will be the same.
Step-by-step explanation:
So since the 2 angles are congruent they will be the same. So for example, if I have a triangle and angle 60 and two congruent angles it will be 60 + 2x =180. I congruent angle will be x then 2 of that is 2x. Angles in a triangle always sum up to 180.
