b = 8
Since 6b and 5b have the same variables, you can subtract them both. 1b, but I'd perfer just b. Then, swap the -8 to the other side. It makes it positive. So it's b = 8.
Answer:
((5*5) + (10-5) * (50/100)) ÷ 3 = 5
((4*4)+(17-8 *(1.378/2)) ÷ 3.445 = 5
Step-by-step explanation:
A = Ao(x)^t
Ao = 500
A = 500(x)^t
400 = 500 (x)^1
x = 4/5
A = 500(4/5)^t << The exp eqn
Answer:
See below
Step-by-step explanation:
<u>Given relationship:</u>
a) r = 3, d = 4
- t = d/r = 4/3 h = 1 h 20 min
b) d = 4 miles, rate = r
- t = 4/r, domain is r and must be greater than zero
c) d = 4 miles, time = t
- r = d/t = 4/t, domain is t and it must be greater than zero
d) t = 3 h, rate = r
- d = rt = 3r, domain is r and can be anything greater than zero
