Answer:
B.) She gets $6.50 per candle.
Step-by-step explanation:
19.5 (the price of 3 candles) divided by 3 is 6.5.
Answer:
45
Step-by-step explanation:
66 nickels = 66 x $0.5 = $3.30
$7.80 - $3.30 = $4.50
$4.50 / $0.10 = 45
Brielle has 45 dimes.
Quinn needs to save another $275.
<h3>How much more money does Quinn need to reach her goal for the year?</h3>
The money that she needs will be equal to the difference between the amount that she wants to save, and the amount that she already has.
- She wants to save $300.
- She already has $25
The difference is:
D = $300 - $25 = $275
This means that, to reach her goal this year, Quinn needs to save another $275.

Answer:
Applying the formulae, (a+b)2+(a−b)2=2(a2+b2)
and (a+b)2−(a−b)2=4ab where a=5x;b=2
4×(5x)×22((5x)2+22)=1213
20x25x2+4=1213
On cross multiplying and simplifying,
75x2−65x+12=0
75x2−20x−45x+12=0
5x(15x−4)−3(15x−4)=0
(5x−3)(15x−4)=
x={53,154}={0.6,0.27}
Hence, m=0.6
