Answer:
960
Step-by-step explanation:
We start with the variable "x". Let's call "x" Raina's penny bank.
After adding 360 pennies, at the end, she has 5/8x, or 5/8.
So we start with
(1/4)x + 360 = 5/8x
Let's subtract 1/4x from both sides
360 = 5/8x - 1/4x
Remember, we need to use common denominators to subtract, so 1/4 becomes 2/8
360 = 5/8x - 2/8x
Now we simplify to get
360=3/8x
Multiply the reciprocal of 3/8 to both sides which is 8/3
360 * 8/3 = x
Answer is 960 pennies.
Therefore Raina's bank hold 960 pennies.

I just took a quiz with this same question :)
Answer:
1.8 cycles
Step-by-step explanation:
The average number of clock cycles per instruction is given by the sum of the product of each possible number of cycles by its likelihood.
1 cycle: 50%
2 cycles : 25%
3 cycles : 20%
4 cycles : 5%
The average number of clock cycles per instruction is 1.8.
(x + 2)(x - 4)
= x^2 + 2x - 4x - 8
= x^2 - 2x - 8
Answer:
3
Step-by-step explanation:
Greatest common factor (GCF) of 6 and 15 is 3. We will now calculate the prime factors of 6 and 15, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 6 and 15.
Hope this helps
