Answer:
x = - 3, y = - 1
Step-by-step explanation:
y = 7x + 20 -----> equation 1
4x - y = - 11
4x - ( 7x + 20 ) = - 11
4x - 7x - 20 = - 11
- 3x = - 11 + 20
- 3x = 9
x = 9 / - 3
x = - 3
Substitute x = - 3 in equation 1,
y = 7 ( - 3 ) + 20
= - 21 + 20
y = - 1
Hence,
x = - 3
y = - 1
Answer: 1 hour 35 minutes
assuming both times were p.m. or a.m. and not one of each
Step-by-step explanation:
60 minutes in an hour.
3 hours 25 minutes = 205 minutes
5 hours = 300 minutes
300-205 = 95 minutes
95 minutes = 1 hour (60 minutes) and 35 minutes
The answer of 6and7 irrational number is 6.875
Answer:
68°
Step-by-step explanation:
Okay, so m<8 is on the same plane as m<7 because line <em>q </em>is intersecting line <em>t </em>and that's supposed to add up to 180° so:
180° - 112° = 68°
So, m<7 = 68°
