Answer:
3x +2=14
subtract 2 from both sides
3x + 2-2=14-2
3x=12
Step 2:Divide both sides by 3.
3x/3 = 12/3
x = 4
Step-by-step explanation:
1.44 per kg
take 1.3 x 2, then subtract 12.7, finally divide that by 7
Answer:
The slope or m is 2
Explanation:
The full answer is y = 2x + 4/3
Slope being 2 as y = mx + b
And the slope is m
It’s the first answer
He can’t just decided what x is he has to solve for it
Answer:
28.8 ft
Step-by-step explanation:
SOH CAH TOA reminds you that ...
Tan = Opposite/Adjacent
The height to the top of the antenna is opposite the angle of elevation, and the distance to the building is adjacent. So, we have ...
tan(58°) = (160 ft +antenna height)/(118 ft)
(118 ft)·tan(58°) = 160 ft + antenna height . . . . . . . multiply by 118 ft
188.8 ft - 160 ft = antenna height = 28.8 ft . . . . . . subtract 160 ft, evaluate
The height of the antenna is 28.8 ft above the top of the building. (The total height of building + antenna is 188.8 ft.)
