Answer:
Step-by-step explanation:
Given the following angle
We want to find angle AOB
∠AOC = 108°
∠AOB = 3x+4
∠BOC =8x−28
Check attachment for understanding
From the attachment, we notice that the sum of angle AOB and angle BOC equals to angle AOC.
∠AOB + ∠BOC = ∠AOC
3x + 4 + 8x —28 = 108
3x + 8x + 4—28 = 108
11x — 24 = 108
11x = 108 + 24
11x = 132
x = 132/11
x = 12°
∠AOB = 3x+4
∠AOB = 3(12) + 4
∠AOB = 36+4
∠AOB = 40°
Extra
∠BOC = 8x−28
∠BOC = 8(12)−28
∠BOC = 96−28
∠BOC = 68°
Answer:
The equation is -20x + 509 = 220
Step-by-step explanation:
Write the equation down. Then subtract 509 from both sides, which will equal -289. You should have -20x = -289. Next, divide both sides by -20, and you will get 14.45 as your final answer. So, it will take about 14 weeks for Heather to have a balance of 220.
Answer:
y=2x
Step-by-step explanation:
This can be shown by inputting the values in the equation.
6 = 2(3) ; 6 = 6 (True)
8 = 2(4) ; 8 = 8 (True)
Answer:
12 times 5=60 not 70
Step-by-step explanation:
12(5+2y)=4y-(5-9y
60+24y=4y-5-9y
60+24y=-5y-5
29y+60=-5
29y=-65
y=-65/29 or y= about -2.38
