Answer:
x=43
Step-by-step explanation:
6x-48 = 4x+38
Step 1: Add 48 to both sides of the equation
6x = 4x +86
Step 2: Subtract 4x from both sides of the equation
2x = 86
Step 3: Divide 2 to both sides of the equation to isolate the variable (x)
x=86/2 so..
x=43
Hope this helps :)
If you multiply 6 3/4 by 16, you get 108, which is how much rope he has in general. If he were to divide this length by 20 for 20 people, that would be 5.4, so each person would get 5.4 meters of rope.
Answer:
Step-by-step explanation:
m∠1+∠2=180
2x+40+2y+40=180
2x+2y=180-80
2x+2y=100
x+y=50
x=50-y
m∠1=m∠3
2x+40=x+2y
2x-x=2y-40
x=2y-40
2y-40=50-y
2y+y=50+40
3y=90
y=30
x=50-y=50-30=20
m∠1=2x+40=2×20+40=80°
m∠2=2y+40=2×30+40=60+40=100°
m∠3=x+2y=20+2×30=80°
