First of all, you should know/notice that
You should also know how negative exponents work:
So, if you wanted
the answer would be x=3, but since you want 125 to be at the denominator, the answer is x=-3:
Answer:
N= 3.8
Step-by-step explanation:
9514 1404 393
Answer:
6
Step-by-step explanation:
If 60% are yellow, the other 40% are green. Then the difference between yellow and green is 60% -40% = 20% of the total number of fish. That difference also happens to be half of the number of green fish:
20% = (1/2)(40%)
So, the number of green fish is 2×3 = 6.
_____
If you wanted to, you could write a couple of equations:
y - g = 3
y = 0.60(y +g)
Using the first equation to write an expression for y, we get ...
y = g +3
Using this in the second equation, we have ...
g +3 = 0.6(g +3 +g)
g +3 = 1.2g +1.8 . . . . eliminate parentheses
1.2 = 0.2g . . . . . . . . subtract g+1.8
1.2/0.2 = g = 6 . . . . . divide by 0.2
There are 6 green fish in the aquarium.
Answer:
Felicia's gross monthly income = $4,583.33 (Approx.)
Step-by-step explanation:
Given:
Annual income = $55,000
Find:
Felicia's gross monthly income
Computation:
Gross income per month = Annual salary / Number of month in year
Gross income per month = Annual salary / 12
Felicia's gross monthly income = Annual salary / 12
Felicia's gross monthly income = 55,000 / 12
Felicia's gross monthly income = $4,583.33 (Approx.)
