Caitlin buys some apples and some oranges. She buys twice as many apples as oranges. Each apple costs £0.25 Each orange costs £0

Vitek1552 [10]

Answer:

Step-by-step explanation:

Caitlin buys twice as many apples as oranges.

$2a=o$

Apples cost 0.25 and Oranges cost 0.30, we have a maximum of 5 to spend.

$5-2a(0.30)-0.25a=0$

$5=2a(0.30)-0.25a\\5=0.6a-0.25a\\5=0.35a\\a=14$

A certain species of tree grows an average of 0.5 cm per week. Write an equation for the sequence that represents the weekly hei

Anestetic [448]

For this we will use equation:

H = starting height + rate_of_growth*periods
We can mark H with index w to represent how many weeks have passed.
Because all of this we can write:

Hw = 200 + 0.5*w

To calculate height after some number of weeks all you need to do is to exchange w with number of weeks.
