A. 3x + 1.50y the variables are x and y
B. If x = 73 wristbands and 47 buttons then:
3(47) + 1.50(47)
141 + 70.5 = 211.5
There you go!!
The nearest whole number is... 12560. It is already a whole number!
Answer:
5^a= 1/5^3
5^a= 5^-3
a=-3
Step-by-step explanation:
4 grams sample will be left after 1 year
Step-by-step explanation:
The decay function for percentage decay is given by:

Here,
a is the initial value
r is the rate
x is the number of time periods
Given
Initial value = 100 grams
Rate = 6% = 0.06
Time = 1 year = 52 weeks
Putting the values in the formula

Hence,
4 grams sample will be left after 1 year

Multiply both sides by (3*5)
5(2n)=3(n+14)
distribute
10n=3n+42
minus 3n both sides
7n=42
divide both sides by 7
n=6
