Answer:
V=8250-18*c
Step-by-step explanation:
The equation will be:
Where:
- V is the volume of corn in the silo after loading begins.
- 8250 is the initial volumen on the silo before the loading begins.
- 18 is the 18 cubic feet per hour given as rate of loading.
- c is the number of hour elapsed after loading begins.
To find the volume, V, of the corn in the silo c hours after loading begins, we substract from the initial volume the quantity of corn loaded and this is 18*c, that is the number of hour elapsed multiplyed by the rate of loading.
x+y=131973
x=y+473
2y+473 = 131973
2y = 131500
y= 65750
x= 65750 + 473 = 66223
65750 + 66223 = 131973
so one country is 65750 and the second country is 66223
Answer:
Simplifying
(2j + 1) * 9 + -7j = 0
Reorder the terms:
(1 + 2j) * 9 + -7j = 0
Reorder the terms for easier multiplication:
9(1 + 2j) + -7j = 0
(1 * 9 + 2j * 9) + -7j = 0
(9 + 18j) + -7j = 0
Combine like terms: 18j + -7j = 11j
9 + 11j = 0
Solving
9 + 11j = 0
Solving for variable 'j'.
Move all terms containing j to the left, all other terms to the right.
Add '-9' to each side of the equation.
9 + -9 + 11j = 0 + -9
Combine like terms: 9 + -9 = 0
0 + 11j = 0 + -9
11j = 0 + -9
Combine like terms: 0 + -9 = -9
11j = -9
Divide each side by '11'.
j = -0.8181818182
Simplifying
j = -0.8181818182
