Answer:
8 times
Step-by-step explanation:
2 x 8 = 16
64 + 16 = 80
10 x 8 = 80
ANSWER:
- x – 3y = 2 ...(1)
- 2x – 6y = 6 ...(2)
On solving eq(1), we get
Plug the value of x in eq(2)
- 2x – 6(x - 2/3) = 6
- 2x – 2(x – 2) = 6
- 2x – 2x + 4 = 6
- 0 = 6 – 4
- 0 ≠ 2
So, given system of equations is not correct.
For the wooden box, if you do 7560 ÷ 180 you get 42. that's how many boxes you would need. multiply 42 by the cost of the wooden boxes: 42 × 0.70 you get 29.40 dollars
for the plastic container, do 7560 ÷ 126 which equals 60, the amount of plastic containers you would need. multiply 60 by the plastic containers cost: 60×40= 24 dollars.
to save money, the company should use the plastic containers because it costs less than the wooden ones.
Answer:
The value of variable r in the equation 
is 
Step-by-step explanation:
We need to find the value of variable r in the equation
Step 1: Write the equation
Step 2: Subtract 4 on both sides
Step 3: Divide both sides by 4
So, The value of variable r in the equation is
1 billion dollars × 6 inches per dollar = 6 billion inches / 63,360 inches per mile = 94,636.97 miles coverted by1 billion bills. answer = 94,636.97 miles
