Answer:
The answer is x = -5
Step-by-step explanation:
In order to find the answer, we first have to put the equation into numerical terms.
14x - 8 = 20x + 22
Now we can solve this using the order of operations.
14x - 8 = 20x + 22 -----> subtract 20 x from both sides
-6x - 8 = 22 ----> add 8 to both sides
-6x = 30 -----> divide both sides by -6
x = -5
Answer:
a) m∠3=113°
b) x=8 (but check below)
Step-by-step explanation:
a) we know m∠1=m∠5
6x-5=5x+7
x=12
we also know m∠1+m∠3=180°
plug x into the formula for m∠1
m∠1=67
m∠1+m∠3=180°
67+m∠3=180°
m∠3=113°
b) Again, we know since those lines are parallel that m∠4=m∠8
x²-4x=32
x²-4x-32=0
(x-8)(x+4)=0
x=8 or x=-4
i think (not 100% sure about this part lol) but x cannot be negative so it's 8
again i'm not sure but it is either 8 or 8,-4.
Im assuming you mean the sides of a triangle which the answer would be no as 1+4 does not equal to 25. (A2+b2=c2) for a right triangle
Answer:
<em>2.5 hours</em>
<u>Skills needed: Speed, distance, time problems</u>
Step-by-step explanation:
1) We are given speed and distance, and have to find out the the time (in hours).
- In terms of units, everything is matched up (Since distance and speed use kilometers, and speed and time use hours).
- Time is always the distance you travelled (how far) divided by how fast you travelled (the rate/speed)
---> We can use the formula for time: 
t= time
d=distance
r=rate/speed
2) Now, let's plug in for distance and rate.
---> 
2.5 hours is the answer.
