Answer:
x=4
Step-by-step explanation:
3x = 12
divide by 3
x =12/3
1/4=0.25 miles
5/0.25=20 laps
José has to run 20 laps to run 5 miles.
Answer:
9
Step-by-step explanation:
Answer:
∠L = 43°
∠M = 121°
∠N = 16°
Step-by-step explanation:
<u>Start by setting all sides equal to 180</u>
3x - 5 + 7x + 9 + x = 180
<u>Add like terms</u>
11x + 4 = 180
<u>Solve for x</u>
11x + 4 = 180
- 4 - 4
11x = 176
/ 11 /11
x = 16
<u>Now, plug in 16 for all instances of x on the triangle and solve.</u>
∠L = 43°
∠M = 121°
∠N = 16°
