Answer: 
Step-by-step explanation:
three-fifths of a number means multiply three-fifths by a variable 
increased by 10 means addition +10
together it is 
There are 5 more payments of interest
= 5 * 0.07 * 950 = 332.5
so amount in the account after 6 years = 950 + 332.5 = 1282.5
Part 1 8.19 meters
11 * .305 = 3.355
8 * .305 = 2.44
3.354 + 2.44 = 8.19
it will cost $252 to cover it
you need 9 square meters to cover 8.19 meters of area
so 9 * 28 = 252

Answer: 
units is the exact length of AB</h3>
===============================================
Explanation:
Use the distance formula to get this answer. The idea is you subtract the x coordinates together, and do the same for the y coordinates as well. Square each result and add up those squares. The last step of the formula is to apply the square root to get the distance from A to B, which is also the length of segment AB.

Therefore, 
Answer:
Joey has 18 nickles and 27 dimes in his piggy bank.
Step-by-step explanation:
1 nickle = 5 cents
1 dime = 10 cents
$1 = 100 cents
$3.15 = 135 cents
Let
n represent the number of nickles, n>=0
d represent the number of dimes, d>=0
Joey counted a total of 45 coins that added up to $3.15:
n + d = 45
5n + 10d = 315
n = 18 nickles
d = 27 dimes
