Answer:
a = 3
Step-by-step explanation:
Here you can use the cross multiplication strategy or whatever it's called. That's where you multiply the diagonals together. Its kinda long to explain, but you can google it for details.
In either case, you get the following equation:
8(2a-1) = 4(a+7)
Open the parenthesis
16a - 8 = 4a + 28
Subtract 4a from both sides
12a - 8 = 28
Add 8 to both sides
12a = 36
Divide both sides by 12
a = 3
Sorry for weird formatting I'm on an ipad.
Joan is correct.
prime numbers: 2, 3, 5, 7......
if you multiply 2 and 3 you get 6...and six is not a prime number, therefore Greta is incorrect.
hope this helps :)
Answer:
V = 1384.7 or 1385.4
(look at explanation)
Step-by-step explanation:
V = pi r^2 (h)
V = pi (49) (9)
V = pi (441)
V = 1384.74 if pi is 3.14
if pi is longer
V = 1385.44236
