The unit rate would be how many miles they drove in 1 hour.
To find that, divide total miles driven by total hours driven.
392 miles / 7 hours = 56 miles per hour.
The unit rate is 56 miles per hour.
Answer: 5y = -11
Step-by-step explanation:
-2x + y = -5
(-2x - 4y = 6) -1
-2x + y = -5
2x + 4y = -6
System by elimination method
0 + 5y = -11
5y = -11
Answer:
b.
42+x+90+8=180° linear pair
x=180-140=40°
<em>x=40°</em>
c.
10+x+90+3x=180 linear pair
4x=180-100
x=80/4=20
<em><u>x=20</u></em>°
