<span>The answer is 2 people. Jim and Holly are 2 persons making 2 gingerbreads for 2 minutes. So, for both of them, 2 minutes are necessary for 2 gingerbreads. Let's calculate how many gingerbreads they can make for 400 minutes. 2 min : 2 gingerbreads = 400 min : x gingerbreads. x = 2 gingerbreads * 400 min : 2 min = 400 gingerbreads. So, the two of them can make 400 gingerbreads for 400 minute without anyone's help.</span>
The Order of Operations is a set of rules that explain to the mathematician which operation goes first when solving an equation. It is the step by step roadmap for the mathematician when it comes to solving an equation.
Set up a system of equations and say green route is x and blue route is y
This will give you
Monday 6x + 5y= 52
Tuesday 12x + 13y = 119
Solve by multiplying the top equation by two to get
12x + 10y= 104
Since you have 12x in both equations, these cancel out when you subtract the bottom from the top. This leaves you with
-3y=-15
Y=5
The blue route is 5 miles, but they want to know the green route. Fill in the y value in either one of your equations. Let’s use the one from Tuesday
12x + 13 (5) = 119
12x= 54
X= 4.5
This means that the answer is 4.5 miles
t = 6.25 years
(about 6 years 3 months)
Equation:
t = (1/r)(A/P - 1)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year,
then, solving our equation
t = (1/0.04)((2500/2000) - 1) = 6.25
t = 6.25 years
The time required to get a total amount, principal plus interest, of $2,500.00 from simple interest on a principal of $2,000.00 at an interest rate of 4% per year is 6.25 years (about 6 years 3 months).
