Sure.
The common difference is 1/3
d = 8/15 - 1/5 = 8/15 - 3/15 = 5/15 = 1/3
d = 13/15 - 8/15 = 5/15 = 1/3
So the seventh term is
S_n = S_1 + (n-1)d
S_7 = (1/5) + 6(1/3) = 11/5
The sum is the average of the first and last times the number of elements
(1/2)(1/5 + 11/5)(7) = 7(6/5) = 42/5 = 8.4
Answer: 42/5
Multi-step equations are equations that require more than one step to solve.
For example:
2x+6 = 10 You subtract 6 from both sides
2x= 4 Divide both sides by 2
x=2 It took 2 steps to solve for x, so it is a muti-step equation.
One step equation:
2x =6 divide 2 by both sides
x=3 It only took one step, so it is an one-step equation.
Hope this can help you! Please put branliest answer if you like it!
Answer:
Answer is 50g/cm^3
Step-by-step explanation:
soln,
Volume of the gold cube = 9 cm^3
Mass of the gold cube = 450 g
now,
density= mass/volume
=450 / 9
=50 g/cm^3
{Therefore, the density of the gold cube is 50 g/cm^3.}
1/2*4 IS 2
BECAUSE 2 and 4 can be cancle out 2 and there 2 let.
I hope that is make sense
