Answer:
y = -5 10/11
Step-by-step explanation:
12(5+2y)=4y-(5-9y)
Distribute
12*5 +12*2y = 4y - 5 +9y
60 +24y = 4y - 5 +9y
Combine like terms
60+24y =13y -5
Subtract 13 y from each side
60 +24y-13y=13y-13y -5
60+11y = -5
Subtract 60 from each side
60+11y-60 =-5 -60
11y = -65
Divide by 11
11y/11 = -65/11
y =-65/11
Change to a mixed number
11 goes into 65 5 times (5*11=55) with 10 left over
y = -5 10/11
A regular hexagone has 6 sides and it divide the subscribed circle into 6 arcs,
Each arc has a measure of 60° (60° x 6 = 360°).
Then if you rotate the hexagone by 60° (clockwise or anticlockwise), it will rotate on itself
Angle BCD is equal to 77 degrees
That's easy, it is 126 divided by 6 equals 21 meters. cause the formula is base times height = area so you do the opposite of it which is base = area divide by height
Answer:
u = <3.5,2>
Step-by-step explanation:
u = 4<cos(30°), sin(30°)>
= 4<√3/2, 1/2>
= <2√3, 2>
≈ <3.5, 2>
