We need to write system of equations for this problem. Reading text we write 1 equation by 1.
first lets name our variables
x - Kiana cards
y - Gary cards
z - Monty cards
m - Willa cards
x = y-3 which we can write as y = x+3
z = x + 7
m = 2z
x + y + z + m = 74
I think easiest way to solve this is to express all variables in last equation and solve for x.
x + x+3 + x + 7+ 2x + 14= 74
5x = 50
x = 10
now we just calculate cards given to each friend
y = 13
z = 17
m = 34
Answer:
Could anyone help me with this problem please?
What is one value that makes the fraction (x^2 + 11x +30)/(4x + 44x^2 + 120x) Undefined?
Need real help I'm so stressed out
Step-by-step explanation:
The total amount Ernest owes the bank after 9 months is $1,225.00
How many months of interest would be paid?
The fact the loan was taken for nine months means that the borrower, Ernest needs to pay interest for nine months, in other words, we would time-apportion the annual interest of 30% to determine the 9-month interest as shown below:
9-month interest rate=30%*9/12
9-month interest rate=22.50%
The amount Ernest is owing the bank is the principal borrowed plus the interest for 9 months as computed below:
total amount owed after 9 months=$1000*(1+22.50%)
total amount owed after 9 months=$1000*1.2250
total amount owed after 9 months=$1,225.00
