Answer:

x=16

Step-by-step explanation:

\frac{x}{8}  + 3 = 5

Take the 3 to the other side of the equation

\frac{x}{8}  = 5 - 3

\frac{x}{8}  = 2

Cross multiply

x = 8 \times 2

x = 16

During the cold winter months, a sheet of ice covers a lake near the Arctic Circle. At the beginning of spring, the ice starts t
Masja [62]

Answer: The ice sheet's thickness decrease every 6 weeks= 1.5 meters

Step-by-step explanation:

GIven: At the beginning of spring, the ice starts to melt. The variable sss models the ice sheet's thickness (in meters) t weeks after the beginning of spring. s=-0.25t+4

At t=0, s=4

So, Thickness of ice sheet at the beginning = 4 meters

Now at t= 6, we get

s=-0.25(6)+4=-1.5+4=2.5

Thickness of ice sheet after 6 weeks = 2.5 meters

Decrease in thickness = 4 meters - 2.5 meters = 1.5 meters

Hence, the ice sheet's thickness decrease every 6 weeks= 1.5 meters

kompoz [17]

Step-by-step explanation:

\bold{1.}\\\\\ mmnn=m^2n^2=(mn)^2\\\\\bold{2.}\\\\3x=5+7\\3x=12\qquad\text{divide both sides by 3}\\x=4\\\\\bold{3.}\\\\\dfrac{x}{3}=7\qquad\text{multiply both sides by 3}\\x=21\\\\\bold{4.}\\\\0.5x=12\qquad\text{multiply both sides by 2}\\1x=24\\x=24\\\\\bold{5.}\\\\4x-6=2x+4\qquad\text{add 6 to both sides}\\4x=2x+10\qquad\text{subtract 2x from both sides}\\2x=10\qquad\text{divide both sides by 2}\\x=5

\bold{6.}\\\\3x^2\ for\ x=6\ /\text{put x = 6 to the expression}/\\\\3(6)^2=3(36)=108\\\\\bold{7.}\\\\3y^2+2y\ for\ y=3\ /\text{put y = 3 to the expression}/\\\\3(3)^2+2(3)=3(9)+6=27+6=33

Please help for 7c please...

I believe x is equal to 16.5 degrees.

Angle OTA is 33 degrees, and each vector of the angle is tangent to the circle, which makes the arc length of the circle 33 degrees as well.

x is on the opposite side of the circle, and the vectors of its angle contain the same portion of the circle as angle OTA. Since the angle point is on the opposite side of the circle, the arc length is double that of the angle.

Simply divide 33 by 2 and presto: 16.5 degrees.

I hope this helps! :)
