The answer is: 1 + 5a ; or, 5a + 1 .
______________________________
Given the expression:
______________________________
<span>1 + 10a − 5a ;
________________
→ We identify the "like terms" ;
___________________________
→ which are "10a" and ( "-5a") ;
____________________________
→ 10a </span>− 5a = 5a ;
_________________________________
→ 1 + 5a ; is the most simplified; or write the expression as: 5a +1 .

Answer:
(y+7)²/364 - (x+8)²/364 = 1
Step-by-step explanation:
This is the standard form of a vertical hyperbola (y-k)²/a² - (x-h)²/b² = 1
so, (y²+14y+?) - (x²+16x+?) = 251
(y²+14+49)-49 - (x²+16x+64)-64 = 251
(y+7)² - (x+8)² = 251 + 49 + 64
(y+7)² - (x+8)² = 364
(y+7)²/364 - (x+8)²/364 = 1
Answer:
300 miles
Step-by-step explanation:
10 mile per second
30 second is 10 x 30
10 x 30 = 300
She gets $20 per week allowance.......she babysits 2 hrs a week at 5.50 per hr.....so she gets (2 * 5.50) = $ 11 per week from babysitting...so she is making a total of (20 + 11) = $ 31 per week. But she pays 2.50 a week for school lunch.......so she is basically making (31 - 2.50) = 28.50 per week.
28.50w < = 149.99
w < = 149.99 / 28.50
w < = 5.26 weeks....but if u need it rounded, it would take her approximately 6 weeks....because 5 weeks wouldn't be enough time
Answer: m∡B°=38,2°.
Step-by-step explanation:
a=3, b=5, c=7 ∡B°=?

m∡B°=arccos
m∡B°≈38,2°.
Good luck!
