The answer is B. Just multiply all of them then divide
<span>Since RT bisects QS, we have QT congruent to ST. Bisect means it cuts QS in half. The we have RT congruent to RT since it is the same. By SSS, we have triangle QRT congruent to triangle SRT since QT is congruent to ST, RT is congruent to RT, and QR is congruent to SR. Each side is congruent to its respective side in the other triangle and that is SSS (side, side, side).</span>
Answer:
80 marbles
Step-by-step explanation:
so he 50
50+20+10+50=80
so its 80 marbles
8 -6g + 15 = 19
You want to isolate the terms (separated by +) that doesn't have letters next to it, to the other side.
So, get 8 and 15 to the other side by subtracting both sides. They don't have letters next to them.
-6g =-4
Divide the -6 on both sides to get "g" alone.
g = 4/6
Simplify
g= 2/3
11-19m=-16m-16
move -16m to the other side
sign changes from -16m to +16m
11-19m+16m =-16m+16m-16 ( combine like terms)
11-19m+16m=-16
11-3m=-16
move 11 to the other side
sign changes from +11 to -11
11-11-3m=-16-11
-3m=-16-11
-3m=-27
divide both sides by -3 to get +m and by itself
-3m/-3=-27/-3
m=9
Check solution by using substitution method
11-19m=-16m-16
11-19(9)=-16(9)-16
11-171=-144-16
-160=-160
Answer:
m=9
