Answer:
Notebook = $2.75
Pencil = $1.25
Markers = $ 0.50
Step-by-step explanation:
Stan:
n + 3p + 2m = 7.5
Jan:
2n + 6p + 5m = 15.50
Fran:
n + 2p + 2m = 6.25
Stan - Fran:
p = 1.25
Lets replace p with 1.25
n + 3(1.25) + 2m = 7.5
2n + 6(1.25) + 5m = 15.50
n + 2(1.25) + 2m = 6.25
Simplify
n + 3.75 + 2m = 7.5
2n + 7.5 + 5m = 15.50
n + 2.50 + 2m = 6.25
n + 2m = 3.75 stan
2n + 5m = 8 jan
n + 2m = 3.75 fran
stan = fran
jan - 2(stan)
m = 0.5
n = 2.75
LCM of 6 and 12 is 6 because you reduce the two numbers with 2 and in the end, you get 3. So, you multiply the two numbers and you get 6.
Answer:
The and is x-2)-2(x + 3)3=0
Let's first write down the equations which we will require to solve for this problem.
Equation No. 1 -
x km/h = y mph
Equation No. 2 -
8 km/h = 5 mph
First of all, we will make y the subject by calculating the km/h when mph = 1. We will accomplish this by dividing both sides by 5 as displayed below:
Equation No. 2 -
8 km/h = 5 mph
5 mph = 8 km/h
5 / 5 mph = 8 / 5 km/h
1 mph = 8 / 5 km/h
Through this, we have found out:
m = 8 / 5
We will use the y = mx formula in order to obtain our final equation. We will substitute the value given in the second equation into the formula.
y = mx
y = ( 8 / 5 ) x
