Answer:
x = -3.25
Step-by-step explanation:
2/5 = 0.4
0.4x - 0.2 = -2(3/4)
-2(3/4) = -2/1 * 3/4 = -6/4
0.4x - 0.2 = -6/4
Convert to fraction
2/5x - 1/5 = -6/4
Add 1/5 to both sides
-6/4 + 1/5 = -30/20 + 4/20 = -26/20
2/5x = -26/20
Convert to decimal
0.4x = -1.3
-1.3/0.4 = -3.25
x = -3.25
X^2 = 7^2 + 24^2x^2 =49 + 576x^2 = 625
x = 25
Given that,
A population p of migrating butterflies changes over time it is represented by the equation
Where w is number of weeks.
To find,
The population after 2 weeks.
Solution,
We have,
Put w = 2 in the above equation.
So, the population after 2 weeks is 64000
.
Hi there!
The greatest common factor of 40 and 24 is 8.
8 goes into 40 5 times:
8 goes into 24 3 times.
We can rewrite this expression for distribution using the amount of times 8 goes into both numbers:
8(5 + 3)
Using this, we get:
8(5) + 8(3) = 40 + 24.
0.90 and I think .9 is another I'm not sure but I tried
