5/9(F-32)= -62.1 what is F?​
nlexa [21]

Answer:

F = -79.78

Step-by-step explanation:

You need to set F by itself

5/9(F-32) = -62.1

multiply the reciprocal of 5/9 on both sides to eliminate 5/9. The reciprocal is 9/5

-62.1 times 9/5

= -111.78

F-32 = -111.78

add 32 on both sides to get F by itself.

-111.78 + 32 = -79.78

Your final answer

A large mixing tank currently contains 350 gallons of water, into which 10 pounds of sugar have been mixed. A tap will open, pou
Marysya12 [62]

Answer

Let t be number of minutes since tap is opened

water is increased by 20 gallons of water per minute.

sugar increase rate of 3 pounds per minute

water :- W(t) = 350 + 10 t

sugar :- S(t) = 10 + 3 t

concentration

C(t) = \dfrac{S(t)}{W(t)}

at t = 15 minutes

C(15) = \dfrac{S(15)}{W(15)}

C(15) = \dfrac{10 + 3\times 15 }{350 + 10\times 15}

C(15) = 0.11

at beginning t = 0 minutes

C(0) = \dfrac{S(0)}{W(0)}

C(0) = \dfrac{10 + 3\times 0}{350 + 10\times 0}

C(0) = 0.0286

C(15) > C(0)

hence, concentration is increasing as time is passing.

A grandmother says her grandson is two years older years older than her ganddaughter and that together , they are at least 12 ye
suter [353]
 let x represent granddaughter and x +2 for grandson and together they = 12
 so then we have the equation of x+2+x = 12
 combine like terms 2x +2 =12
-2 from both sides to isolate x
2x=10  divide both sides by 2 to get x by itself 
so we get x = 5 then add 2 +5=7 
so grandson is 7 and granddaughter is 5
