Answer:
n = 1.2
Step-by-step explanation:
3n = 3.6
Divide both sides by 3 to get n by itself.
3.6/3 = 1.2
n = 1.2
Answer:
1/2 or .5
Step-by-step explanation:
solve for x in the bottom equation
x = 4 - 8y
substitute the equation for x back into the top equation
4(4- 8y) - y = 3y + 7
solve for y
36y = 9
y = 1/4
substitute y back into the equation solving x
x = 4 - 8(1/4)
solve for x
x = 4 - 2
x = 2
xy = 1/4 * 2
xy = 1/2
when multiplying two binomials together we use the F.O.I.L. method:
First
Outer
Inner
Last
(7-3i)(2-i)
First: 7 * 2 ..... Outter: 7 * -i .... Inner: -3i * 2 ...... Last: -3i * -i
First: 14 ...... Outter= -7i ..... Inner: -6i .... Last: 3i^2
putting this together we get 14-7i-6i+2i^2
We combine like terms and end up with 2i^2-13i+14
Answer: 250 mL Juice container
