Remark
The trick here is to remove the brackets carefully. Once you have done that the problem is almost solved.
- 2 = - (n - 8) Multiply both terms inside the brackets by - 1
-1 * n = - n
-1 * -8 = + 8 Be very careful with that. Make sure you understand that two minus's make a plus.
- 2 = - n + 8 Add n to both sides.
-2 + n = -n + n + 8
-2 + n = 8 Add 2 to both sides.
-2 + 2 + n = 8 + 2
n = 10
You should check this.
-2 = -(10 - 8)
-2 = -(2)
- 2 = - 2 and it checks.
Answer:
m<23 = 57° & m<24= 33°
Step-by-step explanation:
You have to create an equation that equals 90°.
(x+24)+x=90
2x+24=90
2x=66
x=33
m<23 = 33+24= 57° so m<23= 57°
m<24= 33°
Its 34
Because it shoukd equal 180 so when you do 101+45= 146 then you subtract 180-146= 34
Answer:
A is b/c the 2 minutes and 54 seconds are 174 seconds and the .29 also gets carried over, so it is 174.29. (You are converting minutes to seconds [60 seconds=1 minute])
B the average time of the four runners would be 43.5725 seconds, b/c 174.29/4=43.5725
