T=650mi(hr/50mi)=13 hr
t-1=12 hr
12=650/(50+v) multiply both sides by 50+v
600+12v=650 subtract 600 from both sides
12v=50 divide both sides by 12
v=25/6 mph
v≈4.17mph
I’d need to know the question to answer this.
Answer:
Step-by-step explanation:
4x^2 is the quadratic
3x is linear
-6 is the constant.
Answer:
-7.5
Step-by-step explanation:
Simplify
-4b - 5 + 2b = 10
-2b - 5 = 10
-2b = 15
b = -7.5
You should expect
5. There is one grey marble out of 9 total, and that can be expressed as 1/9. Since you repeat it 45 times, it's
1/9 45 times, or 1/9(45).

1*45 is 45
9*1 is 9.
45/9 is
5.
