N = 5
Because you have to the decimal 5 places to the right.
0.000023 = 2.3×10^5
Answer:
total cost for Samantha to get her degree = $5,128.2
Step-by-step explanation:
Number of trimesters per year = 3
Number of years = 4
∴ Total number of trimesters throughout college = 3 × 4 = 12 trimesters
Tuition per trimester = $2.350
Total tuition (12 trimesters) = 2.350 × 12 = $28.2
cost of books per trimester = $425
cost of books throughout college (12 trimesters) = 425 × 12 = $5,100
total cost for Samantha to get her degree = total cost of tuition + total cost of books
total cost for Samantha to get her degree = 28.2 + 5,100
total cost for Samantha to get her degree = $5,128.2
Here you have a system of 2 equations and 2 unknowns. An easy way to solve this type is to isolate one of the variables.
12a + 2b = 8
2b = 8 - 12a
b =

b = 4 - 6a
Now plug 4 - 6a into equation 1 to solve for a.
a + 5(4 - 6a) = 19
a + 20 - 30a = 19
-29a = -1
a = 1/29 (answer)
Now plug a into the equation for b
b= 4 - 6(1/29)
b= 110/29 (answer)
Answer:
A) C = 211
B) C = 15.05
Step-by-step explanation:
To get your answer you need to subtract the final answer with the number in the equation. So... 458 - 247 = 211. Hence C is 211
