Days in boston=x
days in colorado=1.4x
boston+colorado=2.4x
475=2.4x
475/2.4=2.4x/2.4
198=x
198*1.4=277
days in boston=198
days in colorado=277
198+277=475
The answer is D
16.55 divide by 2= 8.275
8.275+8.275+16.55+16.55=49.65
Answer:
No real solutions
Step-by-step explanation:
Use the discriminant formula, D = b² - 4ac
D = b² - 4ac
Plug in b, a, and c:
D = b² - 4ac
D = (8)² - 4(1)(20)
D = 64 - 80
D = -16
Since the discriminant is negative, there are no real solutions
40% of 250 is 250 × 40/100 = 25 × 4 = 10
