At the beginning of the season, macdonald had to remove 5 orange trees from his farm. each of the remaining trees produced 210 oranges for a total harvest of 41790 oranges.

equations
and
answer

Equations: f(t) = 210(t-5)

Initial number of trees(t) = 204

Step-by-step explanation:

Let  t represents the initial number of trees and f(t) represents the total number of oranges.

"Remove 5 orange trees from his farm" means (t-5)

" Each of the remaining trees produced 210 oranges" means

so, the equation become

Also, it is given that total harvest of, 41790 oranges.

⇒f(t) = 41790

Substitute this in the above equation to get t;

Divide both sides by 210 we get;

Add 5 both sides of an equation we get;

199 + 5 = t-5 + 5

Simplify:

204 = t

Therefore, there were initially 204 orange trees

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
