Say the first trip was x.
The second trip would be 2x-4.
The third would be 2(2x-4) = 4x-8
The forth would be 3x+18
The total of these would be x + 2x - 4 + 4x - 8 + 3x + 18
This can be simplified to 10x + 6
This means that 10x+6 = 426
Minus 6 from both sides
10x = 420
Divide both sides by 10
x = 42
Trip 1 = x = 42km
Trip 2 = 2x-4 = 84-4 = 80km
Trip 3 = 4x-8 = 168-8 = 160km
Trip 4 = 3x+18 = 126+18 = 144km
Answer:
150 miles
Step-by-step explanation:
use the pythagoerean theorem
42^2 + 144^2 = c^2
1764+20736=c^2
22500 = c^2
c= 150 miles
It's simple, you just have to times everything. 5000 x 3.2% x 5 years. After calculating these, 3.2 is as 0.032 so there would be three decimal places. So then it will e 5000 x 0.032 x 5
Answer:
(1/9)lnx
Step-by-step explanation:
let’s just look at what’s inside ln
ninth root of x is the same as x to the power of 1/9 (x^(1/9))
now we have lnx^(1/9)
this exponent can be moved to the front of the equation so it equals
1/9lnx
X=23
the triangles are similar by 3: 5•3=15, 12•3=36, so 39/3=x-10
