=7x-6x/2 +10) - (-2x +6x-4)
=x/2+10- 4x+4
= x-8x /2 +14
=-7x/2+14
The answer is A. Angles of a triangle will always add up to 180. If you add up 70+67+57 you are left with 194, which is 14 more than 180. Because we need to be at 180, we can assume that x is a negative number. If we say x is negative 7 we are able to takeaway 7 from 67 and 57. After this, we see that the sum of our angles is 50+60+70=180. Therefore, x=-7 in this situation and angle A is equal to 60. The answer is A.
Answer: 51.54 ft
Step-by-step explanation:
The ladder should be 1 feet away from the wall by each 4-feet that the wall rises, so if we have a 50 ft wall, the distance between the bottom of the ladder and the wall must be:
50ft/4 = 12.5ft.
Now we know the cathetus of our ladder, 12.5ft and 50ft, let's find the hypotenuse, that is:
H = √(12.5^2 + 50^2) = 51.54 feet.
Which is also the lenght of our ladder, so the shortest ladder to climb safely a 50 ft wall is 51.54 ft long.
Answer:
The value of h for given value of p is 9950
Step-by-step explanation:
Given as :
The equation - p + 60 = - h + 10,000 Where h is constant
Now, for p = 10 ,
h = 10,000 + p - 60
Or, h = 10,000 + 10 - 60
Or, h = 10,000 - 50
∴ h = 9950
Hence The value of h for given value of p is 9950 Answer
