Answer:

0.5 inches

Step-by-step explanation:

If 400ft = 2in

then 100ft = x

We simply cross multiply

400x = 200

x = 200/400

x = 0.5in

How do you find the first five terms of a sequence defined recursively
Blizzard [7]
Interesting question. Good to know for computer science.
Suppose you have a function like 
an = 3x - 2 Try the first couple
a1 = 3(1) - 2
a1 = 3 - 2
a1 = 1

a2 = 3(2) - 2
a2 = 6 - 2
a2 = 4 So each term differs by 3
a2 - a1 = 3

an = a_(n - 1) + 3
a3 = a2 + 3
a3 = 4 + 3 
a3 = 7

a4 = a3 + 3
a4 = 7 + 3
a4 = 10

a5 = a4+ 3
a5 = 10 + 3
a5 = 13

I'll do one more and then check it.
a6 = a5 + 3
a6 = 13 + 3
a6 = 16

a6 = 3x -2
a6 = 3*6 - 2
a6 = 18 - 2
a6 = 16 which checks.

So the general formula is
an = a_(n - 1) * k if you were multiplying or
an = a_(n - 1) + k if you were adding. The key thing is that you are working with the previous term.

Three fourths of x increased by 5 is - 7​
Finger [1]

Answer:

x=\frac{8}{3}

Step-by-step explanation:

\frac{3}{4} x+5=7

Subtract 5 from both sides.

\frac{3}{4}x+5-5=7-5

Simplify.

\frac{3}{4}x=2

Multiply both sides by 4.

4*\frac{3}{4} x=2*4

Simplify.

3x=8

Divide both sides by 3.

\frac{3x}{3} =\frac{8}{3}

Simplify.

x=\frac{8}{3}
