Answer:
(1,4,-4).
Step-by-step explanation:
Note: Consider A(2, 7,-5) and B (-3,-8, 0).
Section formula: If a point divides a line segment in m:n, then coordinates of that point are
It is given that C divides AB one fifth of the way from A to B. It means AC:AB=1:5
AC:CB=1:(5-1)=1:4
Using the above formula, we get
Therefore, the coordinates of C are (1,4,-4).
The answer is 1
explanation:
when dividing exponents you have to subtract them, -5 - (-6) is 1.
2 divided by 2 is 1 so, therefore the answer is 1.

1.7=3.4z
1.7/3.4= 0.5
z=0.5
Answer:
Number of dimes = 34
Number of nickels = 13
Step-by-step explanation:
Total number of coins = 47
Coins are in the form of nickels and dimes.
Value of a nickel = 5 cents
Value of a dime = 10 cents
Total value of coins = $4.05 or 405 cents
To find:
Number of nickels and dimes?
Solution:
Let number of nickels =
Money value of nickels = 5
Let number of dimes =
Money value of dimes = 10
Total value of coins =
This value is given as equal as 405.
As per question statement, the equations can be written as:
Multiplying equation (2) with 5 and subtracting from equation (1):
Number of dimes = 34
Number of nickels = 47 - 34 = 13
1) m-13=7
2)m-13=7
m-13+13=7+13
m=20
so he had $20 he spent $13 so $7 was left!
