Answer: -4. Reasoning: We are trying to get the angle of both lines to equal 180. If you add 60+124 together to see how much we have currently, your answer comes up to 184. That’s 4 over what we need, therefore, -4 would be needed to bring the current amount back down to 180.
Answer: segment BC = 36 units
Step-by-step explanation:
As per the given information, we have
B, C and D are three points such that
segment BC = segment BD + segment DC ... (i)
And segment BD = segment DC ... (ii)
If segment BD = 18 units
Then, segment DC = 18 units [From (ii)]
segment BC = 18 units + 18 units [From (i)]
⇒segment BC = 36 units
Hence, length of = 36 units

Answer: He run 7 high-speed intervals and 8 low-speed intervals.
Step-by-step explanation:
Let x = Number of high-speed intervals.
y= Number of low-speed intervals .
He runs high-speed intervals in 16 seconds, and low-speed intervals in 23 seconds, and he runs a combined total of 15 intervals in 4 minutes and 56 seconds.
4 min 56 sec = (4(60)+56) sec = 296 sec [ 1 minute = 60 seconds]
According to the question , we have the following linear equations :
Multiply (i)by 16 , we get
Subtract (iii) from (ii)
Put value of y in (i) , we get
Hence, he run 7 high-speed intervals and 8 low-speed intervals.
