a) 2 pounds of Sour Patch Kids
b) 3 pounds of Rolos
Step-by-step explanation:
Given,
Pounds of candy bought = 5 pounds
Cost of sour patch per pound = $2.25
Cost of Rolos per pound = $1.75
Total amount spent = $9.75
Let,
x = Number of pounds of sour patch
y = Number of pounds of rolos
x+y=5
x = 5-y Eqn 1
2.25x+1.75y=9.75 Eqn 2
Putting value of x from Eqn 2 in Eqn 1
Dividing both sides by 0.5
Putting y = 3 in Eqn 1
a) 2 pounds of Sour Patch Kids
b) 3 pounds of Rolos

Answer:
see explanation
Step-by-step explanation:
We require 2 equations with the recurring decimal placed after the decimal point.
let x = 0.7272.... (1) ← multiply both sides by 100
100x = 72.7272... (2)
Subtract (1) from (2) thus eliminating the recurring decimal
99x = 72 ( divide both sides by 99 )
x = =
Answer:
f(- 6) = 9
Step-by-step explanation:
to evaluate f(- 6), substitute x = - 6 into f(x)
f(- 6) = - × - 6 + 5
= - + 5 = 4 + 5 = 9
