Answer:
c
Step-by-step explanation:
To solve this problem, you can use a simple table to find the number of quarters and dimes:
type of coin I Quantity of coin I Value of coin (in amount of money)
------------------------------------------------------------------------------------------------------
dimes I x I 10x (a dime is equal to 10 cents)
------------------------------------------------------------------------------------------------------
quarters I 18-x I 450-25x (a quarter is equal to 25 cents)
After doing this table, you can form the equation:
10x + 450 - 25x = 420
-15x = -30
x = 2 dimes
18-x = 16 quarters
Answer: acute 90-
Step-by-step explanation:
Which one is it tell me the question
Answer:
- (x + 2.4)² + (y + 4.8)² = 45
Step-by-step explanation:
<u>Circle equation:</u>
- (x - h)² + (y - k)² = r², where (h, k) is the center, r - radius
<u>Substitute the values to get the equation:</u>
- (x - (- 2.4))² + (y - (-4.8))² = (√45)²
- (x + 2.4)² + (y + 4.8)² = 45
