For this case we have that by definition, the Greatest Common Factor (GCF) is the largest factor that 2 numbers have in common.
So, we have the following expressions:
We look for the positive integers that divide to 35 and 42 without leaving residue:
42: 1,2,3,6,7,14,21
35: 1,5,7
Thus, the GCF of 42 and 35 is 7
Then, the GCF of the three expressions is:
Answer:
Answer:
x+y=11
Step-by-step explanation:
take the square root of both sides.
(x-7) + (y+3) = 7
collect like terms
x+y = 7+7-3
<span>"Y is inversely proportional to the cube of x" translates to Y = kx</span>³ where k is unknown constant. We need to solve for k.
So we have Y = 3 and x = 2. Plug in and we get 3 = k2³ = 8k
So k = 3/8
Now we can solve for Y when x = 3
Y = (3/8)3³ = (3/8)27 = 81 / 8
Final answer: 81 / 8
Answer:
0.29 = 29% = 
35% = 0.35 = 
= 0.40 = 40%
Step-by-step explanation:
Answer:
The number of coins is missing, so I looked for a similar question:
Darla counted 472 pennies, 319 nickels, 436 dimes, and 271 quarters
Darla can make:
9 rolls of pennies (worth $4.50)
7 rolls of nickels (worth $14)
8 rolls of dimes (worth $40)
<u>6 rolls of quarters (worth $60)</u>
total amount of money = $118.50
