Answer:
Step-by-step explanation:
-11x - 72 = 84 + x
combine like terms on opposite side of =
(-11x )+ (-1x) = (84) + (72)
-12x = 156
divide both sides by -12 to isolate x
-12/-12 = 156/-12
x = -13
insert (-13) for x
(-11 * -13) -72 = 84 + (-13)
71 = 71
equality means its right
306 gallons of milk containing 6% butterfat contain 18.36 gallons of butterfat.
x - the number of gallons of 7% milk
y - the number of gallons of 4% milk
204 gallons of 7% milk and 102 gallons of 4% milk should be used.
Answer:
Using the formula

Solving for r
r=C
2π=35
2·π≈5.57042
Step-by-step explanation:
<span>1.6625 x 10−21</span>
<span>mass of one helium atom x 250 </span>
Express 250 as 2.50.
(6.65 x 10−24)(2.50 x 102)
16.625 x 10<span>−22</span>
