Each truck weighs five tons.
1st truck: n
2nd truck: n + 2
3rd truck: n + 4
4th truck: n + 6
n + n + 2 + n + 4 + n + 6 = 32
4n + 12 = 32
- 12 - 12
--------------------
4n = 20

4 4
n = 5
Answer:
8, 18 and 36 respectively.
<h2>explanation</h2>
sum=54
1st number=x
2nd number=x+10
3rd number =2(x+10)=2x+20
x+x+10+2x+20=54
put the liketerms together
x+x+2x=54-10-20
4x=24
divide both sides by 4 to get
x=8
Input the other values

Answer:
<h2>
$1250</h2>
Step-by-step explanation:
Use the formula i = prt
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year,
then, solving our equation
P = 400 / ( 0.04 × 8 ) = 1250
P = $ 1,250.00
The principal required to
accumulate interest of $ 400.00
on a rate of 4% per year for 8 years is $ 1,250.00.
