the length of a rectangle is 2 cm less then 7 timea the width. The perimeter is 96. Find the Width and Length

1 answer:

5 0

Length = 7width - 2

perimeter = 2 width + 2 length
96 = 2 width + 2 (7width -2)
96 = 2 width + 14 width - 4
100 = 16 width
then width = 6.25 cm and length = 7(6.25) - 2 = 41.75 cm

a country's population in 1994 was 52 million in 2000 it was 55 million estimate the population in 2003

atroni [7]

[email protected] = 52,000,000
[email protected] = 55,000,000
[email protected] = ?
r = ?

Equation: P = Po * e^(rt)
-----
Solve r:
P/Po = e^(rt)

ln(P/Po) = rt
r = ln(P/Po)/t
r = ln([email protected]/[email protected])/(2000-1994)
r = ln(55M/52M)/6
r = 0.009348

----
Solve for [email protected]
t = 2003 - 1994 = 9

[email protected] = [email protected] * e^(rt)
[email protected] = 52M * e^(0.009348*9)
[email protected] = 56,564,292.9

approximately 57M.

What is 35 = -2x - 15 ?

gtnhenbr [62]

Answer:

x=-25

Step-by-step explanation:

35=-2x-15

add 15 to both sides, cancels the 15 from the right

50=-2x

divide both sides by -2, isolates the x
