Answer:
x = 11 ,
<APT = 6x + 1 ➡ 67°
<PTA = 9x - 24 ➡75°
<PAT = 5x - 17 ➡ 38°
Step-by-step explanation:
(5x - 17) + (9x - 24) + (6x + 1)=180°
20x - 40 = 180°
20x = 180° + 40°
20x = 220°
x = 11
Answer:
72.
Step-by-step explanation:
Number of strings with exactly 2 1's
= 9C2
= 9*8/2*1
= 36.
Same for 2 0s
= 36.
1.5r+15=2.25r
Combine like terms: 1.5r+15-1.5r=2.25r-1.5r
15=0.75r
Get the unknown alone: 15/.75=.75/.75r
20=r or r=20 :)
<u>Answer:</u>
Beto will get to the school first.
<u>Step-by-step explanation:</u>
We are given that Delia lives 3/4 mile from school and walks at a pace of
16 minutes per mile.
So Delia takes 
12 minutes to reach school.
While Beto lives 3 1/2 miles from school and bikes at a pace of 3 minutes per mile.
So Beto takes 
10.5 minutes to reach school.
Therefore, Beto will get to the school first.
X must be greater than 0 and y must be less than 0.
I hope this helped.
