Answer:
- The equation 2n = p should be 2p = n.
- The actual cost of the onions is $3.00 per pound.
- Potatoes cost $1.50 per pound.
Step-by-step explanation:
The wording "onions cost twice as much as potatoes" is understood to mean the cost per pound of onions (n) is equal to two times the cost per pound of potatoes (2p). Then the appropriate equation would be ...
2p = n
Then the solution is ...
6p +3(2p) = 18
12p = 18
p = 18/12 = 1.50
n = 2p = 2(1.50) = 3.00
__
The equation should be 2p = n; onions cost $3.00 per pound; potatoes cost $1.50 per pound.
Answer: 6%
Okay, so this is how we are going to find the Interest rate (Work):
156/5=31.2
31.2 Dollars every year
31.2/520=.06
.06x100= 6% interest rate every year
I hope this helps, Have a great rest of your day. :)

Step-by-step explanation:
Hence, the equation for the question (7) is 
and equation for (8) is 
. It can be solved by linear equation in one variable.
What is a linear equation in one variable?
A linear equation in one variable is written as 
. Here, 
and 
are constants and 
is a variable.
(7)
Consider n number of baseball cards does Mike have. Since this is 19 less then the cards Allan have hence, as you add 19 in n then it will give 84.
(8)
Consider the speed of Michelle is n. As, it is 3 times less than the speed of the Jamie hence, it you multiply 3 with n then it will give 12.
Hence, the equation for the question (7) is and equation for (8) is .
