Well , my topic is about "The Revolution of Chocolate" . ( :

Alright Ms.Sue . Thank youu :]

It's (1/4)t...

How come 14 doesn't get reduced to the sq. root of 7i. I would think you'd divide by two on the top and bottom: 6/2=3, 14/2=7).

Formula: A(t)=Pe^rt A=3*300=900 r=3.5%=0.035 P=300 => 900=300e^0.035t =>3=e^0.035t =>ln3=lne^0.035t =>1.09=0.035t =>t=1.09/0.035=31 yeears

x+y=21(*) 3x-4y=0 (**) (*)=>x=21-y Replace to (**):=> 3(21-y)-4y=0 =>63-3y-4y=0 <=>7y=63=>y=63/7=9 y=9 replace (*)=>x=21-9=12 =>x=12 y=9

Or describe it please

Thank you!!!!!

It is the line, but with a negative slope and a different intercepts, equation is 3x + 4y = -110 (50 multiplied by 40 is 2,000, not 200 :-) )

D, B, A?

I don’t know 🤷‍♀️

How many millimeters equal to 15 cm

Let's make it all the same denominators. 1/3 = 5/15. 2/5 = 6/15 5/15 + 6 /15 = 11/15 15/15 - 11/15 = 4/15 4/15 is the total fraction he swims. If 1200 is 4/15 then we divide 1200 by 4 which is 300. 1/15 is 300. 300× 15 = 4500 4500 meters is the total distance if the race.
