Answer:
x = 5
Step-by-step explanation:
For the parallelogram to be a square we use the property
The diagonals of a square are congruent, hence
12x - 23 = 4x + 17 ( subtract 4x from both sides )
8x - 23 = 17 ( add 23 to both sides )
8x = 40 ( divide both sides by 8 )
x = 5
Answer:
The rate is 2.4% per year.
Step-by-step explanation:
The basic formula is Dividend equals Principal times rate times time.
Time is usually the number of years
Dividend means the same as Interest, but we can use D instead if <em>I </em>which is confusing. So D=Prt
Principal is the original amount invested or deposited
You are given D = 96, P = 800 t = 5
r is unknown, that's what you have to solve to find
Put the numbers into the formula: 96 = (800) × r × (5)
Divide: 96/(800)(5) =r That's 96 ÷ 4000 = r Calculate that to get 0.024 and change the decimal to a percent.
That means the rate of interest is 2.4%
