5x can be written as x + x + x + x + x
Answer:
6.5:2.5 or 6.5/2.5 or 6.5 to 2.5
Step-by-step explanation:
A ratio is two numbers put together by a colon, slash (fraction), or "to"
This particular questions asks for math to English, so put in the Math ratio first then English.
The average rate of change of the population from 2007 to 2012 is

which is to say that every five years you can expect 29 more visitors.
So if there were 607 visitors in 2010, then you could expect around 607+2*29=665 visitors in the year 2020.
Step-by-step explanation:
Given
y = x + 3.....equation 1
y = x - y
or y + y = x
or 2y = x
or y = x / 2......equation 2
Now
Putting equation 2 in equation 1
x / 2 = x + 3
x - x/2 = - 3
<u>2x</u><u> </u><u> </u><u>-</u><u> </u><u>x </u> = - 3
2
x / 2 = -3
x = - 6
Now
y = x/ 2
= - 6/2
= - 3
Hope this helps
Hi there!
The question here is asking us to multiply two functions together - j(x) and k(x). First, we need to determine the expressions for j(x) and k(x). Since this is given, we can move straight onto multiplying the two functions together, which will give us our answer.
j(x) × k(x)
Substitute expressions -
(x⁴ - 81)(x + 3)
Simplify -
(x⁴ - 81)(x + 3)
x⁵ + 3x⁴ - 81x - 243
Therefore, the answer is x⁵ + 3x⁴ - 81x - 243. Hope this helped!
