each side = (x+7)
Answer:
$(3b+2)
Step-by-step explanation:
The cost of making b bracelets = 4+5b
The cost of making b necklaces = 8b+6.
To determine how much more it cost to make b necklaces than b bracelets, we simply subtract.
Extra Cost = Cost of b Necklaces-Cost of b Bracelets
=(8b+6)-(4+5b)
open the brackets
=8b+6-4-5b
Collect like terms
=8b-5b+6-4
=3b+2
It costs $(3b+2) more to make b necklaces than b bracelets.
Answer:
$56,558.1
Step-by-step explanation:
This is a question on compound interest.
The formula to calculate the Total Amount based on compound interest is given as:
A = P( 1 + r/n) ^nt
A = Total or Final amount in the account after t years
P = Principal/ Initial amount invested=$35,000
r = Interest rate = 12%
n = compounding Frequency = daily = using 30 days in a month = 30 × 12 = 360 days
t = time in years = 4
A = $35,000( 1 + 0.12/360)^360 × 4
A = $56558.08
Approximately to the nearest cent ≈ A = $56,558.1
Therefore, Priscilla should be expecting $56,558.1 in the account after 4 years.
Add 170,000 and 180,000 together then divide by 2. The number is 175000.
2x+y-3z=12
2x=4z-y
x=2z-y/2
