Alright, so 3f-g=4 and f+2g=5.
3f-g=4
f+2g=5
Multiplying the first equation by 2 and adding it to the second, we get 7f=13 and by dividing both sides by 7 we get f=13/7. Since f+2g=5, then we can plug 13/7 in for f to get 13/7+2g=5. Next, we subtract 13/7 from both sides to get 2g=3+1/7=22/7 (since 3*7=21 and 21+1=22). DIviding both sides by 2, we get 22/14=g. Plugging that into f/39g, we get (13/7)/(22*39/14)
= (13/7)/(858/14)
= (13/7)*(14/858)
=182/6006
= 91/3003 (by dividing both numbers by 2)
= 13/429 (by dividing both numbers by 7)
= 1/33 (by dividing both numbers by 13)
Answer:
okay ans is A(w)=w2+5w-1/8piw2
Answer:
Step-by-step explanation:
Container A = 75.36 x 17 = 1,281.12
Container B = 62.8 x 18 = 1,130.4
1,281.12 - 1,130.4 = 150.72 is left in container A.
So, 1,130.4 was taken out of it.
1,281.12 divided by 1,130.4 = 1.13
move the decimal over two to the right. Or times it by 100.
113%
the equation would be y = 30 + x and if your brother will read for 15 minutes then you'll read for 45 minutes i believe.
The population of the Bulbul birds at the start of the migration season is 1800.
<h3>
Exponential function</h3>
An exponential function is given by:
y = abˣ
Let y, x are variables, a is the initial value and b is the multiplication factor.
Let P be the population of the bird t days since the start of the migration season.
The population of the Bulbul birds at the start of the migration season is 1800.
